It adopts dry pressure measurement technology without intermediate liquid, fully utilizing the technical advantages of ceramic sensors, making the pressure transmitter have excellent technical performance. It has strong overload and impact resistance, high stability, and high measurement accuracy. FB0802 ceramic capacitive pressure transmitter has multiple models, ranges, process connection forms and materials, and can be widely used in many industrial fields such as petroleum, chemical, power, metallurgy, pharmaceuticals, food, etc. It can adapt to various occasions and media of industrial measurement and is an ideal upgraded product for traditional pressure gauges and pressure transmitters. It is also an ideal pressure measuring instrument in the field of industrial automation.
★ Features
※Strong resistance to overload and impact
Overvoltage can reach several to a hundred times the range.
※High precision and good repeatability,high stability
Better than 0.1% F.S/year
※Small temperature drift
Due to the elimination of the intermediate liquid in the measuring element, the sensor has achieved high measurement accuracy and is less affected by temperature.
※Strong anti-interference ability
Waterproof, dustproof, vibration proof, explosion-proof, and anti-corrosion.
※Easy installation
The product has a reasonable structure, small size, light weight, and can be installed directly at any position.
