The devices work via the principle of a bellow-supported paddle which triggers directly a microswitch in case of flow or no flow.
●Suitable for nominal pipe sizes DN 65, DN 80 and DN 100 (further pipe sizes on request)
●Micro switch with gold contacts
●Process connection male thread R1“
●For temperature range from -40 °C up to +140 °C
Handling and operation
Installation and operating instructions can be found in the separate operating manual.
Notes
●Adjustment: the switching point is set at factory in a defined nominal pipe diameter with the values specified in the „Technical data“ table above. Different switching values on request. Adjustmens for silicone oil or ester oil are measured in H2O due to their low viscosity. Switching values and Q-max.values for mineral oils depend on the viscosity and can deviate from the specified technical data.
●Switching points set at factory are secured by gluing and cannot be changed later.
●Paddle attachment secured by bonding.
●Include straight calming section of 10 x DN in inlet and outlet
●Provide a filter for contaminated media..
●It must be ensured that the values given for voltage, current, and power are not exceeded. ●The electrical details apply to ohmic loads. Capacitive and inductive loads must be operated using a protective circuit.
