The LS2100 2-Wire Loop Power Level Switch can measure virtually any liquid or dry material making it an excellent choice for point level detection in a variety of industrial applications. The two wire design provides a current output and is perfect for use with PLC’s and DCS systems. The LS2100 level switch has no moving parts to wear out, jam or break, so there is no need for regular maintenance or cleaning. Calibration is a snap, one piece construction makes installation quick and easy.

Overview

The proprietary radio frequency (RF) circuit has a wide tuning range and exceptional temperature stability. When the probe is installed, it is calibrated in the absence of material touching the probe. When the desired product comes into contact with the probe, the milli-amp signal on the 24 VDC Loop changes to indicate level.

The standard probe is made of a solid 316 stainless steel rod, ¾" NPT process connection and the standard insulator is made of Teflon. The standard seals are double Viton "O" rings on the probe and insulator. All the electronics are housed in a cast aluminum explosion-proof enclosure.

The solid stainless steel rod is available in a variety of lengths and is suited for liquids or bulk solids. These probes can be coated with Halar in lengths up to 72 inches.

A blind-end probe option is also available for applications where a wet material build-up may foul a horizontally mounted probe. The blind-end unit has no visible probe because the insulating material completely covers the sensing probe.
