LG190H High Stable Piezoresistive Pressure Sensor Application •Industrial process control •level measure •Gas, liquid pressure measure •Pressure meter •Pressure calibrator •Liquid pressure system and switch •Refrigeration equipment and air conditioner •Aviation and navigation inspection Features •Pressure range 0~20kPa.. .35MPa •Gauge, absolute, sealed gauge •Constant current power supply •Isolated construction, enable to measure various media •019mm standard pressure sensor •Full stainless steel 316L •Wider temperature compensation ~10°C'—H80°C •Long-term stability 0.1%FS/year Introduction LG190H High stable sensor is the piezoresistive pressure sensor with isolated construction and precise compensation. It uses high stable silicon die, housing with outer diameter 019mm 316L stainless steel housing. Wider temperature compensation and zero correction are calibrated by laser trimming technics. The measured pressure is transmitting onto silicon die through 316L diaphragm and inner media, to transform the pressure to electric signal. Construction Diaphragm: stainless steel 316L Housing: stainless steel 316L Pin: Kovar O-ring: Viton Net weight: ~16g Electric Specification Power supply: <2.0mADC Electric connection: Kovar pin or 100mm silicon rubber flexible wires Common mode voltage output: 50% of input (typ.) Input impedance: 3k£2~8k£2 Output impedance: 3.5kQ'v'6kQ Response (10%~90%): <lms Insulation resistor: 100MQ, 1Q0VDC Overpressure: 1.5 times FS Environment Condition Position: deviate 90° from any orientation, zero change «S» 0.05%FS Shock: no change at lOgRMS, (20~2000)Hz Impact: lOOg, 11ms Media compatibility: the gas or liquid which is compatible with construction material and Viton Basic Condition Media temperature: (25±1) °C Environment temperature: (25±1) °C Shock: O.lg (lm/s/s) Max Humidity: (50%±10%)RH Local air pressure: (86~ 106) kPa Power supply:
