The NH93420 series liquid level transmitter is a stainless steel design fully sealed embedded solid pressure group liquid level measuring instrument. The product works in two-ll size, light weight, easy to install, easy to use, suitable for liquid level measurement and control in petroleum, chemical, power plant, urban water supply, water temperature exploration.
working principleThe level transmitter consists of a special air guide cable with a built-in capillary hose, a pressure-resistant connector and a probe. The probe configuration of the input level gauge is a stainless steel core with a diaagm at the bottom and is covered by a perforated plastic housing.
