Operating temperature range Top An operation of the pressure sensor within the temperature range Top,min up to Top,max will not affect the performance of the pressure sensor. 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. Rated pressure pr Within the rated pressure range 0 up to pr,max the signal output characteristic corresponds to this specification. Overpressure pOV Pressure cycles within the pressure range 0 up to pov will not affect the performance of the pressure sensor. Supply voltage Vsupply Vsupply,max is the maximum permissible supply voltage, which can be applied without damages. Vsupply,min is the minimum required supply voltage, which has to be applied for normal operation. 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. Start up time tSTA Time between the start up of the normal operation after power on and the first valid output signal. Offset Vout,0 The offset Vout,0 is the signal output VA(p = 0) at zero pressure. Signal span (Full Scale) Simple output: VFS = FS = Vout(pr,max) – VA0 Non-linearity L (including pressure hysteresis) The non-linearity 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 non-linearity is: L= 12) 13) Vout ( p x ) − Vout , 0 p x − Vout ( pr ) − Vout , 0 pr Response time t10-90 Delay between a pressure change (10 ... 90% pr) and the corresponding signal output change (10 ... 90% FS). Resolution rOUT The resolution of the output DAC (digital/analog converter). For ratiometric output only 80% of DAC range is used.

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 pressure sensors in an environment where condensation may form or in a location exposed to corrosive gases, which will adversely affect their performance. Soldering The thermal capacity of the pressure sensor 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 no-clean flux should normally be used. Flux removal processes are not 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. Operation Media compatibility with the pressure sensors must be ensured to prevent their failure (see page 2). The use of other media can cause damage and malfunction. Never use them in atmospheres containing explosive liquids or gases. Ensure pressure equalization to the environment, if relative 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. Be sure that the applicable pressure does not exceed the overpressure, it may damage the pressure sensor. Do not exceed the maximum rated supply voltage, it may damage the pressure sensor. Do not exceed the rated storage temperature range, 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 this publication. Care should be taken as reversed pin connections can damage the pressure sensors or degrade their performance. Contact between the pressure sensor terminals and metals or other materials may cause errors in the output characteristics.

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). 7.
