Unfortunately those are sending units and operate on Ohms of resistance. The hobbs is strictly a pressure switch which are a normally open switch that closes and completes a circuit at a set pressure.

Transducers change pressure to a voltage output signal. Hobbs are just a micro switch activated by pressure.
