working principle
SLDP3351-DP silicon pressure sensor uses the piezoresistive effect of single crystal silicon to measure the pressure value. The MonoSlicon silicon diaphragm pressure sensor contains an integral overload diaphragm, a pressure sensor and a temperature sensor. The temperature sensor is used as a reference value for temperature compensation. The positive pressure side of the pressure sensor is connected to the high pressure chamber of the sensor capsule, and the negative The pressure side is connected to the low-pressure chamber of the sensor bellows, and the pressure is transmitted to the silicon chip in the sensor through the isolation diaphragm and filling liquid, so that the resistance value of the chip of the pressure sensor changes, resulting in a change in the output voltage of the detection system. Proportional to pressure changes.
Features:
--High stability silicon pressure sensor: no hysteresis, no drift
--Maximum up to ±0.05%, range upper limit/10 years
--High precision: ±0.05%
--Micro range (0~6kpa) turndown ratio 40: 1; medium range turndown ratio 100:1
--Unique ultra-stable differential pressure transmitter, minimum standard range: 1 kPa sensor design, chip overpressure up to 1.5MPa (1500 times overvoltage), completely solve the shortage of metal capacitor differential pressure sensor
--Excellent environmental adaptability: intelligent static pressure compensation and temperature compensation ensure that the transmitter is not affected by temperature, static pressure and overpressure, and control the comprehensive measurement error on site to the minimum
--5-digit backlight LED display, with on-site buttons, convenient for debugging
--Support HART, Modbus, Profibus PA, Foundation Fieldbus, GPRS/CDMA remote, Bluetooth and other communication functions
piezoresistive silicon pressure sensor SLDP3351-DP: The differential pressure (flow) transmitter can measure with high accuracy within the measurement range of -10~10MPa, and the maximum unilateral overpressure can reach 16MPa.
