Introduction
The input type liquid level sensor is a pressure sensor for measuring liquid level. Based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid, the isolated diffusion silicon sensitive element or ceramic capacitance pressure sensitive sensor is used to convert the static pressure into electrical signals, which are then converted into standard electrical signals through temperature compensation and linear correction. It is generally applicable to petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage Liquid level measurement of various media in environmental protection systems and industries.
GXPS400M series level transmitter is a highly reliable, high stability, high accuracy, small size, split level transmitter. Widely used in the detection of a small diameter pipe and the liquid level in the reservoir fluid height. Such as water, oil, mildly corrosive liquids.
The product uses the 1Cr18Ni9Ti stainless steel structure with import oil-filled pressure core, dedicated zoom and V / I transmitter conversion circuit, which can facilitate their zero and full scale calibration and external zero and span programmable regulation.
Abrasion, oil, acid and alkali resistant, high-strength special breathable cable can be used depending on site configuration.
The intrinsically safe certificate; explosion proof; CE certificate.
Non polarity; circulation output lead of the two-wire and three-wire voltage output for both AC and DC.
