FC0802 Ceramic capacitance pressure transmitter

Production Profile

FC0802 ceramic capacitance pressure transmitter adopt ceramic capacitive sensor with the international advanced level,cooperate with high-precision electronic components, assembled through rigorous craft process. It uses dry pressure measurement technology with no intermediate liquid, giving full play to the advantages of ceramic sensor technology, so that the pressure transmitter has excellent technical performance. It has a strong capacity of anti-overload and shock resistance, high stability and high accuracy. FC0802 ceramic capacitance pressure transmitter has various models, measuring ranges, process connections and materials, it can be widely used in many industrial fields of petroleum, chemical industry, electric power, metallurgy, pharmacy, food, etc., it can be adapted to kinds of occasions and the medium of various industrial measurements, it is the traditional ideal upgraded production of traditional gauge and pressure transmitter, and ideal pressure measuring instruments for industrial automation field.

Function features

• Strong capacity of overload resistance and impact resistance

Over voltage up to several times even one hundred times of measuring range.

• With high precision, good repeatability, high stability 
• Superior to F.S 0.1% / year.
• Small temperature drift.

Sensor gets a high measuring precision and is less influenced by temperature, because the cancel of intermediate liquid in measuring element.

• Strong capacity of anti-interference.

Water-proof, dust-proof, anti-vibration, explosion-proof, anti-corrosion

• Easy to install.

With reasonable production structure, small volume, light weight, can be directly installed at any position.
