Input level transmitter

Input level transmitter

Product Details

I. Overview

TC-803 series input level transmitter has small structure, fast response and high measurement accuracy. It is widely used in metallurgy, petroleum, chemical, water conservancy, medicine , food, power environment control and liquid level measurement. In addition, this product has a live indication function that allows easy and intuitive reading of the actual measured level.

Second, the working principle

Static pressure measurement principle: When the liquid level transmitter is put into the liquid, the pressure on the liquid-facing surface of the sensor is P=ρ·g·h+P0

In the formula

P: Pressure on the liquid surface of the sensor Unit: Pa

ρ: measured liquid density unit: Kg/m3

g: local gravity acceleration unit: m/S2

P0: Atmospheric pressure on the liquid level Unit: Pa

h: sensor input liquid depth unit: m

The atmospheric pressure P0 on the liquid surface can be led to the back pressure chamber of the sensor through the air guiding cable to eliminate the P0 of the liquid surface of the sensor, and the measured pressure is P=·g·h, so as long as the pressure P is measured, The liquid level depth H is available. The pressure signal sensed by the sensor is amplified by circuit conversion and outputted with a standard 4-20 mA·DC signal after compensation. This product is suitable for measuring the liquid level of the open container.
