Plastic Housing Pressure Sensors Model 112S
Description
Based on piezoresistive effect, BCM 112S pressure sensors are packaged with plastic housing, with a BCM silicon die (model SE103) mounted on a substrate and accommodate six pins for through-board assembly. There is molded pressure port on the top of the cap, which make the sensor simple for pressure connection.
Thanks to mass production, the 112S series is coincident and low-cost pressure sensor for the OEM user, widely used in medical instruments and monitoring, blood pressure, consumer and sports, process control, environmental monitoring, HVAC etc.
Model 112S pressure sensor can be used to measure presure range of 0~5 to 0~100 psi in gauge or absolute pressure, feature nice accuracy of 0.5%fso in operating temperature ranges of -20~+85°C, the sensor can be excited by constant current of 0.5~1.5 mA, or constant voltage of 5V, resulting in output signal of Wheatsone bridge output voltage (mV).
The sensor is temperature uncompensated, because of silicon resistors are very temperature dependent, so the maximum value of temperature coefficient of SPAN is high to 2.7%fso/10°C (fso = full scale output). It is very important to understand it with various specifications and their effects to accuracy.
