TECHNICAL DATA

APPLICATION

Housing colour:

grey (lower part similar to RAL 7016, upper part similar to RAL 7035)

Flow monitoring of liquid media in pipes from 1 ⁄ 2 “ to 8", for example, oil, cooling and lubricant circuits or as a precaution against a shortage of water.

Ambient temperature: Permissible atmospheric humidity:

−40 to +85 °C

Max. 95% rel. humidity, non-condensing

permissible Medium tempera- ture:

120 °C

Assembly: The device can be mounted in any position.

Operating voltage:

none

Max. switching current: Min. switching current: Max. switching voltage: Min. switching voltage:

15 (8) A

Calming path at least 5 times the pipe diameter before and after the paddle.*

150 mA at 24 VAC, 50 Hz

230 V AC, 50 Hz 24 VAC, 50 Hz

The max. flow can be significantly higher than the maximum setting value of the monitor.

Switching element: Switching contact: Control function:

microswitch

toggler, potential-free

switches if the set value is undershot or exceeded depends on the pipe diameter (see the table of switching values)
