High Accuracy Cheap Air Gas Industrial Chamber Pressure Transmitter

Basic Info

Product Description

Introduction
Adopted advanced capacitive ceramic sensor or piezoresistive ceramic sensor, this pressure transmitters are assembled through high accurate elements and strict assemble process. With high elastic, anti-corrosive anti-shock, anti-abrasive wear, anti-shock and anti-vibration ceramic ensures HXT pressure transmitters have excellent technical performance through the advantages of ceramic sensors are fully utilized by using dry measurement technology without intermediary.
It's characterized by over-load and anti-shock, strong stability and high measuring accuracy.
HXT series pressure transmitters have the characteristics of novel design principle, complete varieties and specification, easy to install and use, intrinsically safe explosion-proof, water proof and dust proof, etc., and also have the function of automatic detection of power supply polarity. Widely used in oil, chemical industry, metallurgy, pharmaceutical food and suits for industrial measure requirements.
Technical characteristic
There're two big differences between HXT series advanced electronic ceramic technology, dry pressure measurement technology without intermediary liquid, thick film electronic technology, SMT technology and PFM signal transmission technology:

1. Adopted ceramic material for measuring element
2. No intermediary liquid and totally solid

Sensor character
Over-load and strong anti-shock
High stability
Small temperature drift
Widely application
Easy to install and maintenance
Overviw
HXT series pressure transmitter pressure sensitive core adopts high performance silicon piezoresistive pressure filling core. The internal ASIC converts the sensor millivolt signal into standard voltage, current or frequency signal, which can be directly connected with computer interface card, control instrument, intelligent instrument or PLC. Current output mode can be used for distance transmission. It has small volume, light weight, all stainless steel sealing structure and can work in corrosive environment. The product is easy to install and has high anti-vibration and anti-impact performance. It is widely used in process control, aviation, aerospace, automobile, medical equipment, HVAC and other fields.
