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 > Electric connection: 100mm silicon rubber flexible wires > Common mode voltage output: 50% input (typ.) > Zero drift or static pressure: <0.05mV/bar

SPT90 Differential Pressure Sensor > Diaphragm: stainless steel 316L > Housing: stainless steel 316L > Pin: Silicon rubber flexible wires > Media compatibility: the gas or liquid which is compatible with stainless steel and FKM > Power supply: (1.5±0.0015) mADC

SPT90 Differential Pressure Sensor The suggested installation dimension is t> 19mm Compensation method 1 . Compensation method M-type, range code 0A-10 for 6-wire system, 12-13 for 5-wire system. 2. The actual electrical connection method, please check the parameter label enclosed with products. 3. SPT90 type sensor has no laser trimming board, it compensates zero drift and temperature drift by outer compensated resistors, please seethe above chart for the connection. Please connect zero trimming resistor R3(R4), the other R4(R3) is short circuit as negative power supply; R1 or R2 is zero temperature...

SPT90 Differential Pressure Sensor 1. The default unit of the company’s products is kPa,1kPa=0.01bar. 2. Please notice that one side of the leading wire is High Pressure Side, the other is Low Pressure Side. Or identify High Pressure Side by mark "+" , and identify Low Pressure Side by mark "- " carefully. 3. Please pay attention to protect the diaphragm, prevent it from damaging. 4. Please do not pull or drag the 6 leading wires. 5. Temperature resistant range of standard FKM O-ring of sensor is -20°C ~ 250°C . When working temperature is lower than -20°C , or sensor is applied in critical environment,...
