Detailed Description
I.Product Overview
This product is mainly suitable for pressure measurement and control of liquid, gas, non-adhesive colloid, and other media. Different from flat membranes, it is equipped with pressure introduction holes, making it suitable for industrial sites with strong vibration and impact. It ensures long-term stable and reliable operation under harsh working conditions. Zirconium alloy and titanium alloy pressure transmitters are also available for highly corrosive environments in food, pharmaceutical, chemical, and other industries.
II.Application Features
1.Suitable for pressure measurement of liquid, gas, non-adhesive colloid, and other media.
2.Diverse structures adapt to various complex working conditions to enhance product reliability and overload resistance.
3.Adopts high-precision strain measurement technology for accurate pressure measurement.
III.Structure and working principle
The sensitive probe is of assembled core or welded core structure, directly sensing the contacting medium without the need for other media conduction. The internally pasted strain circuit converts the medium pressure into an electrical signal, which is then transformed into a standard output signal through high-precision digital amplification and other circuits.
IV.Operating Environment
1.Ambient temperature: -30~70℃;
2.Relative ambient humidity: ≤90% (at 25℃)
3.Atmospheric pressure: 80～106KPa;
4.Applicable to environments with combustible and explosive gases such as coal dust and gas;
5.Free from strong vibration and impact;
6.Suitable for measuring the pressure of various liquids, gases, powders, slurries, etc., compatible with the contact medium materials
