Pressure transmitters for PCB mounting (voltage output)
AC-T series
Symbols and terms
1)
Storage temperature range Tst
A storage of the pressure sensor within the temperature range Tst,min up to Tst,max
and without applied pressure and supply voltage will not affect the performance of the pressure sensor.
2)
Operating temperature range Ta
An operation of the pressure sensor within the temperature range Ta,min up to Ta,max
will not affect the performance of the pressure sensor.
3)
Compensated temperature range Tc
While operating the pressure sensor within the temperature range Tc,min up to Tc,max
,
the deviation of the output signal from the values at 25 °C will not exceed the temperature coefficients.
Out of the compensated temperature range, the deviations may increase.
4)
Rated pressure pr
Within the rated pressure range 0 up to pr (symmetrical output: –pr up to +pr) the signal output characteristic corresponds
to this specification.
5)
6)
Overpressure pOV
Pressure cycles within the pressure range 0 up to pov will not affect the performance of the pressure sensor.
Supply voltage VCC
VCC,max is the maximum permissible supply voltage, which can be applied without damages.
VCC,min is the minimum required supply voltage, which has to be applied for normal operation.
7)
8)
Signal output current IA
IA,max is the maximum permissible sink current of the signal output.
Exceeding (e.g. short circuit) may cause irreparable damages.
DC break down voltage Vis
The pressure sensor withstands a high voltage between the stainless steel pressure connection and the electrical
connection VCC, VA and GND (all short circuited) without damage.
9)
Offset VA0
The offset VA0 is the signal output VA(p = 0) at zero pressure.
10)
Signal span (Full Scale)
Simple output: VFS = FS = VA(pr) – VA0
Symmetrical output: VFS = FS = VA(+pr) – VA(–pr)
11)
Nonlinearity L (including pressure hysteresis)
The nonlinearity is the deviation of the real sensor characteristic VA = f(p) from the ideal straight line.
It can be approximated by a polynomial of second order, with the maximum at px = pr / 2 .
The equation to calculate the nonlinearity is:
VA (px ) − VA0 px
L =
−
VA (pr ) − VA0 pr
12)
13)
Response time t10-90
Delay between a pressure change (10 ... 90% pr) and the corresponding signal output change (10 ... 90% FS).
Supply voltage rejection SVR
While varying the supply voltage within the range VCC,min up to VCC,max at constant pressure and temperature,
the signal output change will not exceed SVRmax
.
14)
15)
Temperature hysteresis
The temperature hysteresis is the change of offset, starting from the value at 25 °C after a temperature change
and return to 25 °C. Determined during temperature cycles in operating temperature range (cycles with 1 K/min).
Temperature coefficient of offset TCVA0
Offset at temperature Tx: VA0(Tx) = VA0(25 °C) + VFS(25 °C) · (Tx – 25 °C) · TCVA0
Values are valid within the compensated temperature range Tc,min up to Tc,max
Out of the compensated temperature range, the deviation may increase.
16)
Temperature coefficient of span TCVFS
Span at temperature Tx: VFS(Tx) = VFS(25 °C) · [ 1 + (Tx – 25 °C) · TCVFS
]
Values are valid within the compensated temperature range Tc,min up to Tc,max
Out of the compensated temperature range, the deviation may increase.

Cautions and warnings
Storage (general)
All pressure sensors should be stored in their original packaging. They should not be placed in harmful environments such
as corrosive gases nor exposed to heat or direct sunlight, which may cause deformations. Similar effects may result from
extreme storage temperatures and climatic conditions. Avoid storing the sensor dies in an environment where condensation
may form or in a location exposed to corrosive gases, which will adversely affect their performance. Plastic materials should
not be used for wrapping/packing when storing or transporting these dies, as they may become charged. Pressure sensor
dies should be used soon after opening their seal and packaging.
Operation (general)
Media compatibility with the pressure sensors must be ensured to prevent their failure. The use of other media can cause
damage and malfunction. Never use pressure sensors in atmospheres containing explosive liquids or gases.
Ensure pressure equalization to the environment, if gauge pressure sensors are used. Avoid operating the pressure sensors
in an environment where condensation may form or in a location exposed to corrosive gases. These environments adversely
affect their performance.
If the operating pressure is not within the rated pressure range, it may change the output characteristics. This may also
happen with pressure sensor dies if an incorrect mounting method is used. Be sure that the applicable pressure does not
exceed the overpressure, as it may damage the pressure sensor.
Do not exceed the maximum rated supply voltage nor the rated storage temperature range, as it may damage the pressure
sensor.
Temperature variations in both the ambient conditions and the media (liquid or gas) can affect the accuracy of the output
signal from the pressure sensors. Be sure to check the operating temperature range and thermal error specification of the
pressure sensors to determine their suitability for the application.
Connections must be wired in accordance with the terminal assignment specified in the data sheets. Care should be taken
as reversed pin connections can damage the pressure transmitters or degrade their performance. Contact between the
pressure sensor terminals and metals or other materials may cause errors in the output characteristics.
Design notes (dies)
This specification describes the mechanical, electrical and physical requirements of a piezoresistive sensor die for
measuring pressure. The specified parameters are valid for the pressure sensor die with pressure application either to the
front or back side of the diaphragm as described in the data sheet. Pressure application to the other side may result in
differing data. Most of the parameters are influenced by assembly conditions. Hence these parameters and the reliability
have to be specified for each specific application and tested over its temperature range by the customer.
Handling/Mounting (dies)
Pressure sensor dies should be handled appropriately and not be touched with bare hands. They should only be picked up
manually by the sides using tweezers. Their top surface should never be touched with tweezers. Latex gloves should not be
used for handling them, as this will inhibit the curing of the adhesive used to bond the die to the carrier. When handling, be
careful to avoid cuts caused by the sharp-edged terminals. The sensor die must not be contaminated during manufacturing
processes (gluing, soldering, silk-screen process).
The package of pressure sensor dies should not to be opened until the die is mounted and should be closed after use. The
sensor die must not be cleaned. The sensor die must not be damaged during the assembly process (especially scratches on
the diaphragm).
Soldering (transducers, transmitters)
The thermal capacity of pressure sensors is normally low, so steps should be taken to minimize the effects of external heat.
High temperatures may lead to damage or changes in characteristics.
A non-corrosive type of flux resin should normally be used and complete removal of the flux is recommended.
Avoid rapid cooling due to dipping in solvent. Note that the output signal may change if pressure is applied to the terminals
during soldering.
This listing does not claim to be complete, but merely reflects the experience of EPCOS AG.

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical
requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application. As a
rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them
than the customers themselves. For these reasons, it is always ultimately incumbent on the
customer to check and decide whether an EPCOS product with the properties described in the
product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or failure
before the end of their usual service life cannot be completely ruled out in the current state
of the art, even if they are operated as specified. In customer applications requiring a very high
level of operational safety and especially in customer applications in which the malfunction or
failure of an electronic component could endanger human life or health (e.g. in accident
prevention or life-saving systems), it must therefore be ensured by means of suitable design of the
customer application or other action taken by the customer (e.g. installation of protective circuitry
or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or
failure of an electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as hazardous). Useful information on this will be found in our Material
Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed
questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order.
We also reserve the right to discontinue production and delivery of products. Consequently,
we cannot guarantee that all products named in this publication will always be available.
The aforementioned does not apply in the case of individual agreements deviating from the
foregoing for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of
the “General Terms of Delivery for Products and Services in the Electrical Industry”
published by the German Electrical and Electronics Industry Association (ZVEI).
