Drop-in level transmitter


  是基于所测液体静压与该液体高度成正比的原理,采用扩散硅或陶瓷敏感元件的压阻效应,将静压转成电信号。 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, and uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the static pressure into an electrical signal.

After temperature compensation and linearity correction. Converted into 4-20mADC standard current signal output. The sensor part of the drop-in level transmitter can be directly poured into the liquid, and the transmitter part can be fixed by a flange or a bracket.

It is extremely convenient to install and use.

Features of Submersible Level Transmitter:


Good stability and high accuracy. Directly put into the measured medium, it is quite convenient to install and use.


Solid structure, no moving parts, high reliability, long service life. It can measure from water, oil and paste with high viscosity. It is not affected by the bubbling, deposition and electrical characteristics of the tested medium. temperature

Degree compensation. With power reverse polarity protection and overload current limit protection.

优势分析: 4.Advantage analysis of input level transmitter :


The input-type liquid level transmitter can convert various level parameter changes into standard current signals and transmit them to the operation control room for remote display or alarm or automatic control by the secondary instrument or computer. Its good

The structure and installation method can be used for continuous detection of liquid level, material level or level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-blocking, anti-cold junction, and solid powdery and granular materials.

Can be widely used in various industrial processes for detection and control.
