Differential Pressure Switch D45C Series

The 0.1 PSI accuracy of this low pressure product is accomplished by use of a welded Ni-Span-C pressure sensing capsule. This material has a "constant modulus" which provides excellent accuracy over temperature. A 0.1 PSI max on/off band is achievable with the momentary switch option. These features make this unit ideal for aircraft cabin delta-p, landing gear warning and various other air speed alerts.
