The HP33 ceramic piezoresistive pressure sensor is an ideal pressure sensing element that can be installed in a metal casing or directly integrated with electronic circuits of machinery and equipment. Full temperature compensation type, ensuring that the maximum temperature drift does not exceed ± 0.04% FS/℃ within the operating temperature range. This structure ensures that the sensor remains highly stable even under harsh conditions. The internal sensing components are fully protected against humidity, dampness, and chemical corrosion. Layout condensation, providing a typical output of 3mV/V, allowing for simple signal adjustment.

Can be mass-produced, high-performance, low-cost OEM applications;

Complete internal protection to avoid humidity and condensation effects;

Excellent corrosion resistance, capable of direct contact with corrosive gases and liquids;

Compact in size and easy to package.
