Phone: Flow Switch FH12B04 ideal for medium flows of oil - 1/2"G
Replaced by:
Flow Switch FH12B04-M12
For detection of medium oil flow.
Description
The fluid flow causes the displacement of magnetic piston and closes the electrical contact of sensor (reed switch).
The Eicos flow switch FH12B04 of 1/2"G port is ideal for medium flows of oil. The sensor has an operation range that allows to adjust the ideal flow of liquid to be detected in application.
The sensor works Normally Open (NO), with ON signal when the flow (liters per minute) is higher that the sensitivity adjusted in the sensor and OFF signal when the flow decreases below the set point.
Electrical output with DIN 43650 connector (included with sensor).
For water applications, see the model FH12B02.
