Chapter 1 Product Introduction

1.1 Preface

CC-L03 submersible liquid level transmitter plays the role of protecting the sensor diaphragm, and can also make the liquid contact the diaphragm smoothly. Anti-condensation design. Built-in miniature signal processing circuit for remote transmission. Has good stability and reliability.

1.2 Product Overview

CC-L03 submersible liquid level transmitter is mainly composed of imported load cell sensor, measurement circuit and process connection. It can convert the pressure signal parameters felt by the load cell into standard current and voltage signals. When the sensor is put into a certain depth in the measured liquid, the pressure of the measured medium is introduced into the positive pressure cavity of the sensor, and the atmospheric pressure Po on the liquid surface is connected to the negative pressure cavity of the sensor through the cable guide tube to offset the positive pressure of the sensor. Po, so that the sensor can measure the pressure , and by measuring the pressure, the depth of the liquid level can be obtained .

1.3 Features

Water Level(0-5M range) output analysis：

Output signal conversion calculation

Output Voltage：I

Level=I/5*5

For example, moment output Voltage is 3.2V.

3.2/5=0.64,0.64*5=3.2M That is, the current water Level is 3.2M.

Chapter 3 Notes

■ Our company's products are provided with instruction manuals and certificates of conformity, including technical parameters, please check carefully to avoid wrong use.

■ The transmitter can be installed vertically, inclined or horizontally in the tank or tank. It should be ensured to avoid the sediment and other magazines burying or blocking the probe part of the transmitter.

■ When connecting the power supply, it should be connected in strict accordance with the wiring instructions of our company.

■ This product is a precision instrument, it is forbidden to disassemble it at will, to prevent collision and drop, and it is strictly forbidden to touch the sensor diaphragm with sharp objects, which will cause damage to the core.

■ When the medium fluctuates greatly, measures should be taken to fix the probe part of the transmitter, such as adding weight to the transmitter.

■ The air guide cable plays a key role in atmospheric compensation. When installing, avoid locking the air guide cable too tightly or bending it too sharply to prevent the air guide pipe from being blocked.

■ Human factors caused by wrong wiring, damaged sensor diaphragm, etc. are not covered by the warranty .
