FLOW MONITOR JSF-1 E…4 E MECHANICAL – TÜV-TESTED
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)
