Piezoresistive Monocrystalline Silicon Differential Pressure Sensor (PC90D)
Product Description
PC90D Monocrystalline Silicon Differential pressure sensor
Features
Imported ultra-high stability differential pressure die
High accuracy and excellent stability
Static pressure error within ±0.1%FS/10MPa
Patented double overpressure protection diaphragm design
Unilateral overpressure limit of up to 40MPa
Constant current/constant voltage excitation
316L stainless steel all welded integrated structure
Positive and negative pressure completely symmetrical, no O-ring inside, with small flange kit
Applications
Differential Pressure Transmitter core component
Differential pressure flow transmitter core component
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.
Example: PC90D-100kH11M1R1
Refer to product model PC90D, with pressure range 0-1.5Pa~100kPa, thread 55-16 British thread, diaphragm material stainless steel 316L, and filling oil silicon oil.
