Overview

LR series liquid level transmitter

As a supporting instrument for side mounted and top mounted magnetic level gauges, the sensor part of the level transmitter is fixed to the magnetic field with a clampThe outer side of the main tube of the liquid level gauge is placed in the same magnetic coupling system as the liquid level gauge, utilizing the characteristic of the dry reed tube in the sensor being magnetically attracted by the magnetic float ball in the liquid level gauge. Convert the change in liquid level position Generate resistance signal output, which can be directly matched with the digital display meter produced by our company Realize remote detection of liquid level Alarm and control.

LB series liquid level transmitter

The difference between the LB series liquid level transmitter and the LR series liquid level transmitter is that the LB series liquid level transmitter is based on the LR series liquid level transmitterOn the basis of the transmitter, an integrated transmission circuit module is installed in the junction box to convert the resistance signal into a binary. 4-20mADC standard signal output. This signal can be easily matched with electric instruments or DCS to achieve remote detection, alarm and control It can also be used in conjunction with the digital display meters produced by our company. Due to the integrated transmission module, it adopts solid packaging, has high integration, and features reverse power protection, low power consumption, and anti vibration Therefore, the work is stable, reliable, and has a long lifespan.

When the magnetic level gauge dominates the movement of the magnetic float inside, the dry reed tube inside the sensor moves in sequence through magnetic couplingBy doing so, the variable resistance signal is obtained, which enables the output of the resistance signal or the conversion into a 4-20mADC current output through the module. The sensor part of the LR/LB series liquid level transmitter adopts ALEPH dry spring switch tube from Japan This solves the problem of magnetization and inability to work properly after long-term use of similar products, and accurately detects liquid levels.

debug

The UHZ-158C (D) side mounted (top mounted) magnetic level gauge and LR/LB bundled remote transmitter are fixed together with clamps after passing calibration and verification when they leave the company. Before installation, users can perform overall debugging.The position indicated by the moving magnetic float and indicator should correspond to the output of the transmitter. The transmitter can also be disassembled for separate debugging The specific method is to place magnetic steel at the zero position mark of the transmitter sensor At this time, the output should be 4mA. Move the magnetic steel to the sensor full mark and the output should be 20mA. If the zero position and full degree exceed the tolerance, adjust the zero position potentiometer and range potentiometer repeatedly. Until the requirements are met. After debugging the transmitter separately, it should be re fixed on the outside of the main pipe of the level gauge with a clamp. It must be noted that the centerline of the lower liquid pipe of the level gauge must be aligned with the zero position of the indicator scale and the zero position mark of the transmitter sensor.

Ordering Instructions

Select and order together with the main UHZ-158C side mounted magnetic level gauge or UHZ-158D top mounted magnetic level gauge. There are three types of junction boxes to choose from: ordinary type, explosion-proof type, and intrinsic safety type.
