Description

The I2R Therm-O-Watch L7-1100SA/28T liquid level monitor consists of a sensing head and an amplifier / controller. It is a heavy duty 1100W capacity unit with a built-in alarm and 28-hour timer. The sensing head clips onto thermometers or other nonmetallic tubing and contains a small electronic oscillator that is sensitive to minute changes in the electrical "capacitance to ground". A change in liquid level affects this oscillator and activates the amplifier. Sensitivity when using polar liquids is determined by the dielectric capacity of the liquid column. In liquid level applications, an 8 mm diameter glass tube containing water has a sensitivity of about ± 0.2 mm.

When a change above or below the preset level is sensed, two power outlets on the front of the unit will be activated. One outlet is normally ON and the other normally OFF. Power output, which varies with each model, can be used to turn heating mantles, cooling systems and other electrical equipment ON or OFF. 

Examples of uses include:

Keeps LC columns from running dry

Controls vacuum (or pressure) when clipped on a manometer

These solid state units can be "piggybacked" with a thermocouple adapter (not included).
