Product Description

The AO910W input type liquid level transmitter uses a diffusion silicon pressure sensitive chip, which converts the liquid level signal of the measured liquid into a 4-20mA DC standard signal through a highly reliable amplification circuit. This product comes in two types of structures: integrated and split type. Armored and anti-corrosion products can resist the erosion of various corrosive liquids and meet the needs of customers to the greatest extent possible. The explosion-proof type product can be applied to various harsh and dangerous places.
