The CM-ENS.13S is a relay from the CM family for level monitoring and level control. The rated control supply voltage is 110-130 V AC, or 220-240 V AC. Output: 1 changeover contact (250 V / 4A). It monitors and controls levels and mixing ratios of conductive liquids. It is used for filling and emptying applications, for dry-run protection of pumps and for signaling the status of the monitored level. Open-circuit principle. The sensitivity can be adjusted using a potentiometer on the front. Various electrodes, as well as a sealable transparent cover to protect against unauthorized adjustment of the settings, are available as accessories.
