GP-1900 To-8 Pressure Sensor
Range from 20 kPa to 1 MPa
Gauge, absolute and differential types
Constant current power supply
Temperature compensation
TO-8 package for PCB mounting
For non-corrosive gases and liquids
The GP-1900 TO-8 pressure sensor is a compact MEMS-based sensing device designed for precise pressure measurement in space-constrained instrumentation. The sensing die is packaged in a TO-8 metal housing, enabling reliable PCB integration while providing stable mechanical protection.
Pressure applied through the sensor port is transmitted directly to the silicon sensing element. The sensor converts pressure into a proportional voltage signal through a linear relationship. Integrated temperature compensation and linear correction ensure consistent measurement performance across the compensated temperature range.
The GP-1900 supports gauge, absolute, and differential pressure measurement configurations, allowing flexible integration into a wide range of industrial and laboratory instruments. Its constant current excitation design simplifies signal conditioning in embedded measurement circuits.
Due to its compact TO-8 structure and stable MEMS sensing technology, the GP-1900 is suitable for instrumentation systems, gas pressure monitoring, laboratory measurement devices, and embedded control systems requiring reliable pressure sensing on printed circuit boards.
