Level Indicators/Controllers

These level controllers are designed to display engineering units using a 4-20 mA level transmitter. It comes in three configurations, with optional two or four programmable relays and an isolated 4-20 mA repeater. Each relay can be configured on a single set point as a high or low level alarm or latched on two set points for automatic fill or empty control in simplex or duplex modes. This controller is suitable for use with general purpose two or three-wire level sensors. The controller features a LED main display and secondary unit display with relay status and can be easily configured via the push button display module. It is housed in a 1/8 DIN enclosure with NEMA 4X faceplate and shallow case and includes an isolated power supply to the sensor with an optional 4-20 mA repeater. The non-volatile memory has security password protection, and the controller also features a 32-point linearization function for volumetric measurement. This controller can be panel-mounted, and for field-mount installation, a single or double NEMA box with optional flash and/or audible alarm can be added. Overall, this tank or silo level controller is a useful tool for monitoring and controlling the level of materials in tanks or silos in a variety of industries.
