Introduction

Principle & Structure

The pressure used to measure the medium can also be converted into a change in liquid level. The use of fully sealed capacitive sensitive elements ensures excellent stability and reliability for those with high measurement accuracy in pressure or liquid level measurement. The product can be equipped with HART communication protocol as an option, and can communicate with the control system or handheld terminal. , through which they are set, monitored, tested and configured.

Features

High precision, high reliability, high stability

Zero point and range are adjustable on site

Long life for continuous level monitoring

4-20mA standard optional configuration HART communication protocol

Optional remote diaphragm seal

Various corrosive media can be measured according to the choice of different diaphragm materials

Explosion proof optional

Damping adjustable

application

Suitable for liquid level monitoring and pipeline pressure monitoring of medium and large tanks

Suitable for the measurement of liquids in tanks, tanks, pits, and corrosive liquids

Mainly used in wastewater/purification treatment, shipbuilding, generator equipment, petrochemical, food

Electronics, dyeing and finishing, chemical, rubber and plastics, hydraulic machinery, chemical and pharmaceutical industries
