    • AO910W Input Type Liquid Level Transmitter

    1、 Overview

     

    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. Split type products also have two types: armored and anti-corrosion. 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 AO910W input type liquid level transmitter product is divided into two types: ordinary type and intrinsic safety explosion-proof type. The explosion-proof type product can be applied to various harsh and dangerous places.
