Crouzet Control Liquid Level Monitoring Relays include single function and multi-function monitoring relays. They can be used for over flow and dry-running protection, for filling and draining applications, for max and min alarm; or any combination of such functions. In agricultural applications, watering, irrigation, drying, distribution and treatment of water, etc., Crouzet Control Level Monitoring Relays are used to manage and protect equipment by controlling emptying and filling levels.

To properly respond to the requirements of level control, the Crouzet Level Control range offers relays that monitor by measuring liquid resistivity and enable adjustment of measurement sensitivity so as to precisely set closing and tripping levels. In addition, a selectable time delay takes wave effect into account, avoiding unwanted closing and tripping due to movements of liquid.

Level Control Relays are available in 6 housing types:

• 17.5 mm DIN Rail Modular
• 22.5 mm DIN Rail Modular
• 35 mm DIN Rail Modular
• 45 mm DIN Rail Industrial
• 39 mm Plug-in 8-pin base
• 39 mm Plug-in 11-pin base

Functions:

• Automation of filling & emptying cycles
• High or low level control
• Check for presence of a conductive or non-conductive liquid by temperature probe or discrete sensor
• Adjustable time delay
