4-20mA Output High Precision Intelligent Capacitive Pressure Transmitter

4-20mA Output High Precision Intelligent Capacitive Pressure Transmitter

1. Overview

This new type intelligent transmitter is designed to meet customers’ requirements for transmitter of easy installation,high stability and high accuracy based on capacitive sensors.
This transmitter has all characteristics of common ones. Meanwhile, its installation method is the same as the diffusion silicon transmitter, showing superb performance in pressure and liquid level environments with narrow space that need high accuracy and stability, and in pressure compensation that utilizes follow quality to finish trade settlement.

Capacitive pressure transmitter(capacitive type pressure transducer) is a pressure transmitter that uses a capacitive sensing element to convert the measured pressure into an electrical output with a certain relationship. It is characterized by low input energy, high dynamic response, small natural effects, and good environmental adaptability. It generally uses a round metal film or metal-plated film as an electrode of the capacitor. When the membrane is deformed by pressure, the capacitance formed between the membrane and the fixed electrode changes. Through the measuring circuit, the electrical signal with a certain relationship with the voltage can be output. Capacitive pressure sensor is a capacitive sensor with variable pole distance. It can be divided into single capacitive pressure sensor and differential capacitive pressure sensor.
