Instruction manual for magnetic level transmitter
I. Overview

Magnetron level transmitter uses magnetic float (ball) as the measuring unit and controls the reed switch through magnetic coupling,
Make the sensor resistance change linearly, and then use a converter to convert this resistance change into a 4-20mA DC current signal for output
Get out. This current signal can be connected to an electric Type III instrument to achieve automatic detection, remote transmission, and control of liquid level.
Suitable for continuous measurement and indication of liquid levels in various storage tanks, storage tanks, pools, and containers in industrial production processes.

This series of magnetic level transmitters has explosion-proof protection performance.

2、 Characteristics and principles
The magnetic level transmitter consists of two parts: a measuring unit and a transmitting unit. Float (ball) and liquid
Synchronize the changes in position, control the suction or disconnection of the reed switch, so that the resistance inside the sensor changes linearly, and then the converter will convert this
The change in resistance value is converted into a 4-20mA standard DC signal output.
The magnetic level transmitter outputs a 4-20mA standard signal and is used in conjunction with secondary instruments to achieve
Realize automatic recording, control, and adjustment of liquid level, and be compatible with industrial control systems to form a relatively good control system.
In some application scenarios, intermediate relays (and secondary instruments) can be omitted, and the application equipment can be directly driven with a circuit form
Flexible and versatile, able to meet the needs of various occasions.
The transmitter with magnetic levitation ball as the measuring unit is particularly ideal for liquid level measurement in underground storage tanks and storage tanks.
The main characteristics of magnetic level transmitter are stable performance, easy installation and use, and no need to adjust the zero and full point on site
The main components are made of stainless steel material, which has strong corrosion resistance.
