liquid level sensor how it works

industrial water level sensor RS-PM200

water level sensor is used to detect the level of substances that can flow. Such substances include liquids, slurries, granular material, and powders. Level measurements can be done inside containers or it can be the level of a river or lake.

The front end protective cap of the PM200 series input type liquid level sensor protects the diaphragm of the sensor, and also enables the liquid to smoothly contact the diaphragm. The waterproof wire is sealed with the outer casing, and the vent pipe is connected to the outside in the cable, and the internal structure is prevented. Condensation design. Built-in miniature signal processing circuit for remote transmission. Has good stability and reliability.


water level sensor description

1. Reverse polarity protection and transient over-current and voltage protection, in line with EMI protection requirements;

2. The temperature can be automatically compensated, and the temperature drift is automatically corrected;

3. The high-quality air-guiding cable can be used to soak in water all year round;

4.Strong overload and anti-interference ability, economical and practical stability;

5. The core automatic correction algorithm can effectively prevent numerical fluctuations caused by water surface fluctuations;

6. The slope type liquid guiding hole can effectively prevent the entry of sludge impurities and can also prevent impact.
