HD181S Series RF Capacitive Level Transmitter is a new type of liquid level measuring instrument developed by our company absorbing the essence of similar products from abroad. It can convert all kinds of level and liquid medium parameters into standard current signals and remotely transmitted to the operation control room for centralized display, alarm or automatic control of secondary instruments or computer devices. Its good structure and installation method can be applied to the continuous measurement of liquid level, material level and material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-blocking, cold-resistance and solid powder, granular materials and other special conditions, which is widely used in electric power, metallurgy, chemical, food, pharmaceutical and other industries and sewage treatment, the liquid level, material level and level measurement of boiler drum, pulverized coal etc..





It has compact structure, small size, simple installation and maintenance, uniform size

Multiple signal output forms to facilitate different system configurations

PTFE probe, acid-resistant, alkali-resistant and other corrosive liquids and high temperature

The immersed liquid measuring part, there is only one PTFE cord or PTFE rod probe as a sensor, with high reliability.

Fully sealed aluminum alloy housing and stainless steel couplings


The high-temperature pressure vessel is as simple as measuring ambient temperature and pressure, and the measured value is not affected by the temperature, specific gravity of the measured liquid, and the shape and pressure of the container.

Measurement, output two ends and measurement, output, power three-therminal isolator a variety of circuit structure, comes with isolator, to adapt to different signal grounding.
It has perfect over-current, over-voltage, power polarity protection.
