[Wotian sharing] input type liquid level transmitter Principles and characteristics of the input level transmitter
From: Issued date 2020.01.22 Back
The input liquid level transmitter is based on the principle that the measured static pressure of the liquid is proportional to the height of the liquid. The piezoresistive effect of diffused silicon or ceramic sensitive elements is used to convert the static pressure received by the sensor into an electrical signal. Temperature compensation and linear correction, converted into 4 ~ 20mA standard current signal output, and can be connected to the control system through the instrument cable for detection and control.
The sensor part of the drop-in liquid level transmitter can be directly poured into the liquid, and the transmitter part can be fixed by a flange or a bracket, which is extremely convenient to install and use. It can be used for water level measurement in urban water supply and drainage, water treatment plants, reservoirs, rivers, oceans, oil storage tanks and petroleum, chemical, power and other departments. The measured medium can be water, oil, acid, alkaline and viscous liquids. .

PCM266 input intelligent liquid level transmitter is a fully stainless steel design and fully sealed submersible intelligent liquid level measuring instrument. This product uses high stability and high reliability piezoresistive OEM pressure sensor and high precision intelligent transmitter processing circuit. It adopts precise digital temperature compensation technology and non-linear correction technology. It is a high precision liquid level measurement product.
The waterproof cable is hermetically connected to the shell, and the vent pipe is in the cable, which can be used in liquid for a long time. The integrated structure and standardized output signals provide convenience for field use and automatic control.
The product works in a two-wire system, with small size, light weight, easy installation, and easy use. It can directly replace the two-wire analog 4-20mA output transmitter.
