German LPE sensor LPE model LPE price

LPE sensor pressure sensor for level measurement. The static pressure submersible level transmitter (level gauge) is based on the principle that the static pressure of the measured liquid is proportional to its height. It uses advanced foreign isolated diffused silicon sensitive elements or ceramic capacitive pressure sensitive sensors to convert static pressure into electrical signals, which are then converted into standard electrical signals (typically 4～20mA/15VDC) after temperature compensation and linear correction.

LPE sensor introduction

Divided into two categories: one is contact type, including single flange static pressure/double flange differential pressure level transmitters, float level transmitters, magnetic level transmitters, submersible level transmitters, electric internal float level transmitters, electric displacer level transmitters, capacitive level transmitters, magnetostrictive level transmitters, servo level transmitters, etc. The second category is non-contact type, divided into ultrasonic level transmitters, radar level transmitters, etc. Static pressure submersible level transmitters (level gauges) are suitable for level measurement of various media in systems and industries such as petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, and environmental protection. The compact structure, simple calibration, and flexible installation methods provide convenience for users. Standard signal output methods such as 4～20mA, 0～5v, 0～10mA can be selected by users as needed. Using the principle of hydrostatics to measure liquid level is an important application of pressure sensors. Special cables with ventilation conduits in the middle and specialized sealing technology are used, which not only ensure the watertightness of the sensor but also allow the reference pressure chamber to communicate with ambient pressure, thereby ensuring high accuracy and stability of measurement.

LPE sensor features

1) Since the output of the liquid level is only related to whether the photoelectric probe contacts the liquid surface, and is unrelated to other characteristics of the medium such as temperature, pressure, density, electricity, etc., the photoelectric level sensor has accurate detection and high repeatability; fast response speed, very precise liquid level control, and can be directly installed and used without calibration. 2) Since the photoelectric level sensor probe is relatively compact, it can be separately installed in narrow spaces, suitable for use in special tanks or containers. In addition, multiple photoelectric probes can be installed on one measuring body to make multi-point level sensors and controllers. 3) Since all components inside the sensor are resin-encapsulated, there are no mechanical moving parts inside the sensor, so the photoelectric level sensor has high reliability, long life, and is maintenance-free.

LPE sensor applications

Widely used in water plants, refineries, chemical plants, glass factories, sewage treatment plants, high-rise water supply systems, reservoirs, rivers, oceans, etc., for the measurement and control of static and dynamic liquid levels in water supply pools, distribution pools, water treatment pools, wells, water tanks, oil wells, oil tanks, oil pools, and various liquids.
