Failsafe level alarm relay and probe

MultiTrode has released the SafeSmart level alarm relay and failsafe probe that provides an additional failsafe detection.

Most wastewater utilities install independent high level backup alarms in case of failure of primary level devices or primary controllers. And around the world, utilities have been moving away from ball floats because they are prone to tangle up and often need cleaning to avoid false readings from fats, oils and grease.

The MultiTrode single sensor level probe eliminates the problems of ball floats and the failsafe version is designed to eliminate the risk of wires becoming disconnected, or rats eating cabling. The SafeSmart level alarm relay continually checks for continuity, so if there is a problem with connection to the probe an output is activated. This provides continuous verification to the utility that the probe is in operation.

The SafeSmart level alarm relay has two outputs — ‘level alarm’ and ‘loss of probe’. These outputs can be normally open or normally closed. The product also has adjustable conductivity settings for different kinds of liquids and adjustable delays.
