SULZER ABS CA 461
The CA 461 is designed to monitor and detect leakage in pumps and mixers. The amplifier is housed in a standard enclosure for DIN rail mounting. The unit is available in two versions: 24 VDC or 110-230 VAC supply.
To minimise the risk of false alarms, a fault must be detected for at least 10 seconds.
For easy installation, the unit is fitted with plug-in connectors.
