SCH-Ex-VCM Pressure Switch
Brand: KOBOLD Instruments, Inc
The negative pressure switches detect the pressure difference relative to the atmospheric pressure. All data on switching pressure ranges and therefore also the scale divisions on the switch units are to be understood at the difference in pressure between the atmospheric pressure at any one time and the set switching pressure.
The "zero" reference point on the scale of the unit corresponds to the atmospheric pressure at the time. The minus sign by the indicated pressure stand for under-pressure below the respective atmospheric pressure.
