Analog output flow sensor PTA series

celduc relais offers a range of magnetic flow sensors. Use celduc’s flow sensors to ensure minimum flows to your systems! - 1 open contact (A form) 250Vpeak - 100VA - 1A - No flow, contact is open / Flow, contact is closed - Two paddle lengths are available (57 or 77mm). Typical application: - To supervise the flow rate in water treatment systems or swimming pool heaters (to indicate a failure or loss of capacity of the dosing pump.) - To ensure that the device is energized when a known volume flow is present in heat-pumps or electric heaters Main advantage: Unlike a pressure switch which can be tricked into giving a yes signal in situations such as a down-stream valve being closed, a flow switch is not affected by pressure and only responds when flow is present.
