siliconvoltage outputDC

Features • Pressure range: 0bar 0.35bar...35bar • Constant current or constant voltage power supply for option • Isolated construction. Possible to various fluid media • OEM differential pressure sensor • Stainless steel 316L • High static pressure 200bar • 2 times overpressure Application • Industrial process control • Differential pressure measurement • Gas, liquid pressure measurement • Pressure checking meter • Pressure calibrator • Ventura and Eddy-current flow meter Introduction SPT90 differential pressure sensor is OEM differential pressure sensor with stainless steel isolated diaphragm. It has integrated construction, high static pressure, high stability and good reliability. The high and low pressure sides are protected by isolated diaphragm. It can be used for measuring corrosive and conductive fluid media. The measured differential pressure is transmitted onto the die through the diaphragm and filling silicon oil so that the sensor could measure differential pressure precisely. The sensor is tested automatically, and compensated zero and temperature performance with provided resistors. The installation dimension is consistent with general products which makes the sensor has a good interchangeability. It is widely used for industrial process control and differential pressure measure fields. etc. Electric Specification • Power supply:≤2.0mADC • Electric connection: 100mm silicon rubber flexible wires • Common mode voltage output: 50% input (typ.) • Input impedance: 3kΩ~8kΩ • Output impedance: 3.5kΩ~6kΩ • Response <1ms • Insulation resistor: 100MΩ@100VDC • Max. static pressure: 200bar • Zero drift or static pressure: sO.05mV/bar
