1、 Overview
Capacitive level gauge is a level transmitter that can be used for liquids, oils, solids, interfaces, and measurements. It has no movable components and greatly improves reliability. It is not affected by water vapor, dust, or condensation, and has the advantages of stable and reliable long-term operation, high sensitivity, good linearity, high temperature resistance, and high pressure resistance. The intelligent level gauge is a two wire (loop powered) 4-20mADC measurement signal, which is easy to adjust and wireless transmission, 485 transmission, etc. It can be widely used in various fields such as petroleum, chemical industry, metallurgy, electricity, papermaking, pharmaceuticals, etc.
As an intrinsically safe product, intelligent liquid level gauges comply with the relevant requirements of GB3836.1-2010 "Electrical Equipment for Explosive Gas Atmospheres - Part 1: General Requirements" and GB3836.4-2010 "Electrical Equipment for Explosive Gas Atmospheres - Part 4: Intrinsically Safe" i ". The explosion-proof mark is ExiblICT6 Ga.
