PROFESSIONAL -The hydrostatic level transmitter sensor determines the liquid level by measuring the static pressure generated by the liquid level. This pressure acts on the pressure sensitive of the transmitter's diffused silicon pressure sensor, and the liquid column pressure is converted into a voltage by the piezoresistive effect of the sensor. This is directly converted to 4~20M by amplification. STABLE PERFORMANCE -Whether it is liquid level measurement of river water, reservoir, or water level monitoring of fire pump station pump station, input type liquid level transmitter has good use effect, even in urban groundwater level monitoring, water treatment tank (processed) Performance is equally good WIDELY USE - Reservoir, river water, well water, water supply tower, sewage pool, level measuring Anti - bending, high - quality solid structure, high reliability. This level sensor adopts of anti-corrosion material, excellent anti-corrosion performance and Anti - blocking design, easy to clean. HIGH QUALITY - 4-20mA transmission output, can be used with digital display, PLC, inverter, recorder and other instruments. The shell is made of 316 stainless steel and durable, and with waterproof cable, safe to use The liquid level sensor is suitable for detecting 0-5m range liquid level JECTSE -Jectse is not just a brand.
