MK Series 2 SPDT High Range Pressure Switch
Brand: Orion InstrumentsMK series pressure switches are housed in pressure die cast Aluminum powder coated enclosure and are recommended for panel mounting or outdoor service based on the type of enclosure opted for.
Stage differential can be set in these 2 SPDT versions (MK series).
Both microswitches are synchronized for operation such that the stage difference (or gap) can be adjusted from minimum 15% of FSR to a maximum of 50% of FSR (on falling setpoints).
The scale indicates falling setpoint for low microswitch.
The repeat accuracy is better than ±2% Full ScaleR. 3/8" cable entries are provided for cables and a terminal strip suitable for wired ends is fitted inside the enclosure.
Other variations for cable termination, such as plugin connectors can be provided.
Pressure port is 1/4" BSPF standard.
