Liquid level monitors and controls
Benefits and advantages

CM-ENE MIN/MAX
– Monitoring of pump systems for dry running (ENE MIN) and overflow (ENE MAX)
– Connection of 2 electrodes possible at C and MIN/MAX
– 3 supply voltage versions

2 – Optimal price/performance ratio

– 1 n/o contact: Open-circuit principle for CM-ENE MIN, Closed-circuit principle for CM-ENE MAX
– LED for status indication

CM-ENS
