equipped with nut and cutting rings. (Pipe connection options 18L, 22L or 28L) Operating mode: The flow detector is based on the thermal basic (calorimetrical principal), whereupon the loss of heat caused by a flowing medium can be detected with a temperature-sensitive resistor (PTC).The MR-AES18L sensor delivers a signal from 4 to 20 mA that is proportional to the flow in order to indicate or regulate the flow – in order to monitor a flow within a certain range, you can program two switchpoints on the MR-BES18L and even lock it electronically. Low tension side: analogue, analogue power output 4-20 mA; Adjustable flow range in l/min: 0-10 for SR-507 18L, 0-20 for SR-537 22 18 22L, 0-40 for SR-537 28 18 28L; oper. current: 20-28 DC; Temperature: Medium: 0° C up to 80° C; Resistance: 30 bar; Material: Sensor: 1.4571, part zinc-plated; Reaction time: 5 sec (from 10% up to 90%); Error: max. 10% (from end value); Display: 10 LED’s; Connection: M12-plug, 4-pole; Protection system: IP 67
