Specifications

pressure and gas brake, it is one of the sensors in dosage. Currently it is widely used as slide wire type or bimetallic strip structured oil pressure gauge. The sensor consists 

of a corrugated diaphragm and a slip line potentiometer. When the pipeline hydraulic or air pressure changes, corrugated diaphragm produces displacement, drives the 

touching spot on the potentiometer sliding, changes its resistance value, so as to realize the dial pressure indicator.
But this kind of pressure sensor has a mechanical touching spot, the touching spot passes the largest l00mA current, when the automobile runs with high speed or 

equipment operates with high power, the actual working condition of the pressure sensor is very bad, more than +110 ℃ high temperature, below -30 ℃ low temperature, 

and frequent shock, vibration, overload, etc., this makes the sensor's mechanical and electrical life are severely affected, this is the main factor why the reliability and life 

expectancy of current domestic product is low, and this is a htac technology bottleneck pressing for solution of automobile and engineering machinery pressure control 

instrumentation.
In view of this,our company cooperates with the international well-known micro sensor experts, have developed "oil and gas pressure sensor", it adopts the international 

latest generation of "pressure sensor", and developed mating ASIC special high integrated circuit, having solved the problems of mechanical structural oil pressure gauge's 

low precision and production quality bad stability, short lifespan, poor sealing, the output signal can not match with the digital instrument, with the characteristics of high 

temperature resistance, corrosion resistance, no touching spot, can match the digital instrument, long life, high cost performance, etc, becomes a oil and gas pressure 

measurement and control sensor product of the new generation.
This oil and gas pressure sensor module is mainly composed of a pressure sensor component, application-specific integrated circuit, MCU, PWM output, it can accurately 

measure the medium pressure.

Characteristics:
Small output error. ±2% FS (including nonlinear, return difference and repeatability, the whole temperature range)
Light weight, small volume, easy to install and operate
No wear, stable performance and long-term small drift, long service life
Fully compatible, can replace the mechanical sensor directly
Perfect surge voltage protection

Introduction:
This series automobile pressure sensor is the electronic new products lauched by us on the basis of many years' research on pressure measurement. The products have 

improved completely in view of the traditional mechanical automotive pressure sensors, have eliminated the mechanical wear inherent problem, while maintaining the good 

performance at the same time provide a very low price. The main function of the product is for measuring the pressure of gas and liquid, can be used in motorcycles, 

engines and other poor working environment.
Products with special medium layer of full digital silicon sensing element, can be long-term under high temperature oil media. Due to silicon sensor has the advantage of 

flexible performance, no mechanical moving parts, it can ensure long-term reliable operation at any auto parts.
Product weight is light, so it can be directly installed on the flow pipe or container, the guiding mouth of pressure sensor can be customized according to users' need, 

directly screwing into process pipelines, about electrical fittings, we can supply line pressing nut, standard insert or all kinds of splices according to users' needs.

Working principle:
This product adopts full digital silicon sensing component with special medium layer, can be long-term under high temperature oil media. Because the silicon sensor has 

excellent elastic performance, no mechanical moving parts, it can ensure long-term reliable operation at any auto parts. Driven by PWM mode header, fully compatible with 

the original moving-coil pointer table and various types of lamp, and completely overcome the mechanical sensors' contact erosion, disconnection, leakage fault caused by 

the mechanical wear.
Because this product is very light in weight, it can be directly installed on the flow pipe or container, the guiding mouth of pressure sensor can be customized according to 

users' need, directly screwing into process pipelines, about electrical fittings, we can supply line pressing nut, standard insert or all kinds of splices according to users' 

needs.
