Using a Thermal Level Switch for Interface (Level) Detection

Instrument malfunctions are a common problem across a wide array of industries. For a segment of our clients, the combination of the process media and plant condition tends to cause instrument malfunctions that require maintenance. For a level switch to perform well it must avoid failure that can be caused by:

• Corrosion and/or “sludging” damage to the sensor caused by the soapy emulsion.
• High temperature
• Water contamination (Feedwater and cooling water often contains high mineral content, sediment, etc.)
• Electromagnetic interference
• Difficult access points limit monitoring and daily maintenance

The Solution: Thermal Level Switch

The Kayden Classic 800 Series Thermal Level Switch is used to provide critical control for interface level in the tank. Our Kayden Thermal Level Switch provides digital repeatability and fast response time. This solution is built in a rugged package that is not bothered by coating on the probe and will not drift. This unit will also never require calibration, which in turn will save you time and potential headaches.

The Display Panel controls allow for the set up to be fast and easy. Our Kayden switches feature all-welded sensors with no moving parts design, true digital electronics with auto diagnostic functions, 2 independent relay timers, a Bypass Timer for auto pump restart, and a 4-20mA analog output corresponding to the process level.
