Brief Introduction

The series of pressure sensor adopts dry ceramic piezoresistive pressure sensitive components with high precision and good stability,   and   reliable   Amplifier   chip.   It   can   change   the   pressure   of tested medium into standard signal. Automatic SMD, laser adjustment technology and advanced assembly process are applied to guarantee its high quality. The series of pressure sensor is a new type with international advanced technology, which is applicable to pressure control for automobiles and HVAC&R Equipments. Voltage output or electrical current output can be designed to customers' choice.

Features
