CA 461 is designed to spy and detect leakage in pumps and mixers. The amplifier is housed in a norm enclosure fitted for DIN-rail mounting. The unit is available in two executions, 24 VDC or 110-230 VAC supply.
To minimize the risk of false alarms the failure has to be detected for minimum time duration of 10 seconds. To simplify the mounting the unit is fitted with plug-in type of connectors.
