Use celduc’s flow sensors to ensure minimum flows to your systems !
Magnetic flow sensors - PTA105xx
-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).
References available :
PTA10534 - with 0,5m cable + short paddle (57mm)
PTA10535 - with 2m cable + short paddle (57mm)
PTA10595 - with 2m cable + long paddle (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.
