Introduction

Float level transmitter

Float level transmitter working principle and product overview:

working principle:

20mA标准信号输出,变送器电源24VDC ,二线制工作形式。 The float type liquid level gauge uses the principle of buoyancy of liquid to magnetic float. The displacement of the magnetic float with the change of liquid level is converted into a standard linear 4 to 20mA signal output. The transmitter power supply is 24VDC . It has the characteristics of stable and reliable work, and no adjustment is required. It can display, alarm and control the liquid level of the medium in the opening, closed container or underground tank. The tested medium can be conductive and non-conductive liquids such as water, oil, acid, alkali, industrial sewage, etc., and can overcome the effect of false liquid level caused by liquid foam.

Product uses and applications:

Widely used in various liquid level measurement, such as oil, water, sewage, acidic liquid, alkaline liquid. Adopt explosion-proof junction box and intrinsically safe amplifier circuit, guide rod and floating ball stainless steel material. Float level transmitters are widely used in oil refining, chemical, paper making, food, and wastewater treatment industries.
