Smartec

 

The Smart Pressure Device SPD series of pressure sensors are silicon based and encapsulated in all kind of housings. The pressure range can vary between about 10 mBar and 20 Bar gauge, absolute  and differential. In case of an absolute version the reference vacuum chamber is formed on the die during manufacturing.
The Smartec Pressure Devices are based on the principle of bending a membrane caused by the pressure in a liquid or gas. On the membrane is a very thin conductive screened layer that follows the bending of this membrane. The resistance of the conductive layers will change when the membrane bends. This bending is measured by means of a Wheatstone bridge
In general the screened resistors are also sensitive to temperature which means a compensation for temperature effects is required. For the Smartec pressure sensors this compensation is done in the amplifier to obtain a stable analogue output.
In the delivery program  a lot of outputs circuits are available like bridge, analogue, digital and I2C output. In case  your requirements are not in the list of data sheets, please, contact your nearest dealer. In general we have the possibility to full fill your needs concerning pressure range and output.
