Silicon Oil-filled Liquid Level Pressure Transmitter
Description
CSS-93420IB series liquid level pressure transmitters adopt CSS series piezoresistive isolated membrane silicon oil-filled sensing elements as the signal measuring elements, according to the mathematical model of the three relations of the measured liquid pressure, density, liquid level, through the liquid level sensor to accomplish the liquid level pressure measurement which is proportional to the depth of the liquid level, and through the signal processing circuit to transform into standard signal output. The special gas leading cable, advanced sealing technology, reliable amplifying circuit and precise temperature compensation technology, make the products have good characteristics of high precision, small dimension, leakage-proof and good performance. They are stable and reliable during long-term immersing in liquid work.
