Product Overview

The OBAI-804X input liquid level transmitter uses a high-performance pressure sensor as a measuring element. Through the pressure sensor, the liquid static pressure that is proportional to the liquid level depth is accurately measured, and converted into a standard (current, voltage or digital) signal output through a dedicated signal conditioning circuit, establishing a linear correspondence between the output signal and the liquid depth, and achieving accurate measurement of the liquid depth. The product has high precision, small size and is easy to use. It can be directly put into the liquid to measure the liquid level from the end of the transmitter to the liquid surface. It is suitable for water level or liquid level measurement and control in the fields of petroleum, chemical industry, power plants, urban water supply, and hydrological exploration.

Main Features

♦The water guide head is a fully sealed stainless steel structure. The sensor and amplifier circuit are both in the stainless steel shell. The protection level is IP68.
♦The top stainless steel cap is removable, which not only prevents accidental damage to the diaphragm, but also facilitates regular cleaning.
♦Suitable for harsh environments such as outdoors and open air
♦No moving parts, stable and reliable performance
♦Fiber marking, exquisite and detailed appearance
