HW181S series RF capacitive liquid level transmitter is a new type of liquid level measuring instrument developed by our company by absorbing the essence of foreign similar products. It can convert changes in various level and liquid medium parameters into standard current signals, which can be remotely transmitted to the operation control room for centralized display, alarm or automatic control by secondary instruments or computer devices. Its good structure and installation method are suitable for continuous measurement of liquid level, material level, and material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti blockage, anti cold formation, and solid powder and granular materials. It is widely used in industries such as power, metallurgy, chemical, food, and pharmaceuticals, as well as in places such as sewage treatment, boiler steam drums, coal powder bags, etc.
characteristic
★ Compact structure, small size, easy installation and maintenance, uniform external dimensions.
★ Multiple signal output forms, convenient for different system configurations.
★ Polytetrafluoroethylene probe, resistant to strong corrosive liquids such as acid and alkali, and high temperatures.
The measuring part immersed in liquid only has one PTFE flexible wire or PTFE rod probe as a sensor, with high reliability.
★ Fully sealed aluminum alloy shell and stainless steel connectors.
★ It is as simple as measuring normal temperature and pressure for high-temperature pressure vessels, and the measured value is not affected by the temperature, specific gravity, container shape, or pressure of the measured liquid.
★ Multiple circuit structures for measuring and outputting both ends, as well as measuring, outputting, and power supply three end isolators, with built-in isolators to adapt to different signal grounding methods.
★ Comprehensive overcurrent, overvoltage, and power polarity protection.
