PC90D Monocrystalline Silicon Differential Pressure Sensor Features ■ Imported ultra-high stability differential pressure die ■ High accuracy and excellent stability ■ Static pressure error within ± 0.15%FS/10MPa ■ Patented double overpressure protection diaphragm design ■ Unilateral overpressure limit of up to 40MPa ■ Constant voltage excitation ■ 316L stainless steel all welded integrated structure ■ Positive and negative pressure symmetrical, no O-ring inside ■ With small flange kit Applications ■ Differential pressure transmitter core component ■ Differential pressure flow transmitter core component Notes: Overview PC90D Monocrystalline Silicon Differential Pressure Sensor is a kind of differential pressure sensor designed with overpressure protection function. The differential pressure sensitive core element adopts high performance piezoresistive silicon chip, which is assembled in all-welded seal structure and filled with silicon oil in high vacuum. Diaphragm of different materials isolates measuring medium and differential pressure die, meanwhile, the sensor performs long-term reliable measurement of differential pressure signals of various strong corrosive media. Differential pressure sensor converts the measured differential pressure signal into millivolt voltage signal proportional to its linearity by external constant current or constant voltage excitation. 1 Do not touch the diaphragm with hard objects, which may cause damage to the diaphragm. 2 Please read the Instruction Manual of the product carefully before installation 2 The information presented in this product sheet is for reference and check the relevant information of the only.
