2% off OEM ISO9001 CE RoHS Dp Piezoresistive Silicon Differential Pressure Sensor Transmitter

Product DescriptionFeatures:Piezoresistive silicon chip employedPerfect long term stabilityMEMS TechnologySensor diameter: 19mmProducts Overviews:PC10D(WTD19) differential pressure sensor is a standard and most popular sensor applied in air and liquid pressure measuring. A high sensitivity silicon pressure chip is employed in the sensor. The housing is filled with oil for pressure transmission. The most important specification for industry application is long term stability. PC10D(WTD19) sensor is designed for industry application with perfect long term stability.Diaphragm and pressure rangeThe diaphragm diameter has tight relation with pressure measured. Low pressure requires large diameter and high pressure needs small diameter. This is caused by oil expansion during temperature changing. It creates internal pressure due to the resistance of the diaphragm. The smaller diaphragm will create large internal pressure, and it is difficult to make zero compensation.   Product Parameters  Pressure range Pressure range10kPa, 35kPa, 70kPa, 100kPa, 250kPa, 400kPa, 600kPa, 1MPa, 1.6MPa, 2.5MPa(bar and psi unit available)Pressure referenceDifferential pressure OverpressureRangePositive OverpressureNegative Overpressure35kPa70kPa35kPa70kPa150kPa70kPa100kPa200kPa100kPa250kPa500kPa250kPa400kPa800kPa400kPa600kPa1200kPa600kPa1MPa2MPa1MPa1.6MPa3.2MPa1MPa2.5MPa5MPa1MPaOutput signal Zero output±2mVSpan output≥40mV (≤35kPa) | ≥60mV (Other ranges)Specification Accuracy (linearity, repeatability and hysteresis)±0.25%F.S.
