LPB210 lightning protection level transmitter

The LPB210 level transmitter uses the principle of fluid statics to measure water level or liquid level, which is an important application of pressure sensors. The highly sensitive silicon piezoresistive sensing element fabricated using micro-machining technology is the intelligent core of the level sensor. With a special cable with a vent tube and specialized waterproof technology, it ensures the waterproofness of the immersion sensor while allowing the reference pressure chamber to communicate with the ambient air pressure, thus obtaining accurate measurement results and excellent stability.

The LPB210 level transmitter utilizes the principle of fluid statics to measure water level or liquid level, representing a significant application of pressure sensors. A highly sensitive silicon piezoresistive pressure-sensitive element, fabricated using micro-machining technology, serves as the level sensor. Combined with a special cable featuring a vent tube and specialized water-sealing technology, it ensures water tightness for the submersible sensor while allowing the reference pressure chamber to communicate with atmospheric pressure, thus achieving accurate measurement results and excellent stability. The LPB210 level transmitter employs a dry ceramic capacitive sensor or a temperature-compensated isolated diaphragm diffusion silicon pressure sensor as the sensing element, significantly enhancing product performance. It is widely used in the measurement and control of water levels and liquid levels in various fields, including petroleum, chemical engineering, power plants, urban water supply and drainage, and hydrological exploration.
