Products Description
The AFLSS-21 Liquid Level Sensor is available in lengths up to 2m long and is designed for environments where monitoring of a variety of liquid types is required. The sensor uses solid-state capacitive technology to sense the level of the liquid, with no moving parts, floats or other mechanical linkages to provide excellent long term reliability.
It features two output options, analogue voltage or current to suit a variety of applications.
Built from 316 stainless steel, the level sensor will provide corrosion resistance in harsh environments. The sensor features SAE 5-Bolt mounting with a 1.25” BSP thread.
A flange gasket and O-ring seal are supplied with each unit.
