PF3W720-F04-ET-NM Applications

The PF3W720-F04-ET-NM monitors both flow and temperature of water or ethylene glycol coolant in a single compact unit, ideal for chiller and process-cooling circuits on welding equipment, machine-tool spindles, moulds and laser sources. Its integrated temperature sensor and PNP switch plus 1 to 5 V analogue output let a PLC track cooling performance and trigger alarms on low flow or overheating. The rotatable 3-colour display improves visibility, and Karman-vortex sensing needs no moving parts. Requires 8 cm straight inlet piping for rated accuracy.
