Product Overview

PT683L Remote Seal Level Transmitter is designed for accurate liquid level measurement in tanks, vessels and industrial process equipment where direct sensor contact with the process medium is unsuitable.

Using a welded remote diaphragm seal and capillary system, the process pressure is transferred through fill fluid to the sensing element while isolating the transmitter from aggressive, high-temperature, viscous or crystallizing media. This construction improves long-term stability, reduces maintenance and extends service life.

With intelligent electronics and HART communication, the PT683L is widely used for level monitoring in chemical processing, petroleum, power generation and water treatment industries.
