FV25B LED Reversable Marine Tachometer
The FV25B Reversable Marine Tachometer uses magnetic or proximity sensors operating in conjuction with a toothed wheel or symmetrically spaced bolt heads, To produce a reverseing speed output.
The sensors are positioned around the rotating gear wheel to give signals which can identify the direction of rotation.
The control card processes the sensor signals & operates dual relays which can be used to indicate direction of rotation.
The same isolated relays can also be used to interlock with external control equipment to produce wrong-way-alarms.
A 0-10 volt output signal is available to drive centre zero or quadrant type analogue indicators.
A 25mm four digit LED display can be fitted which also provides direction of rotation information by forward & reverse LEDS.
Further relay outputs can be provided for under or overspeed alarms & a separate revolution counter can be incorporated.
Features include:
- Switchable Frequency Scaling
- Reversing Relay Contacts
- Magnetic or Inductive Sensor
- Centre Zero or Standard Meters
