Liquid Level Transmitter Anti-Lightning, Anti-RF Interference
Working Principle of Liquid Level Transmitter
The liquid level transmitter is composed of a special air conducting cable with a built-in capillary hose, a compression connector and a probe. The probe structure of the input type liquid level gauge is a stainless steel cylinder core with a diaphragm at the bottom, and is covered by a plastic shell with holes. Liquid level measurement is actually the difference between the hydrostatic pressure on the probe and the actual atmospheric pressure, and then the pressure difference is converted into a 4-20mA output signal by a ceramic sensor (attached to a stainless steel film) and electronic components.
Design feature of Liquid Level Transmitter
◎good stability and high accuracy
◎the structure is exquisite, and it can be directly put into the measured medium to measure the liquid level, which is quite convenient for installation and use.
◎Solid structure, no moving parts, high reliability, long service life, high-precision measurement from water, oil to paste with high viscosity, not affected by the foaming, deposition and electrical characteristics of the measured medium
◎wide range temperature compensation
◎with power reverse polarity protection and overload current limit protection, lightning protection and radio frequency interference protection
