    Pressure sensors are very temperature dependent. In this app (24/7/365), unless you have an active valving assembly that can truly zero it at regular intervals...its prob not good enough as a sole input. Balls in the wall, no such problems at fractions of cost.

    Pissing in the wind without all the specific space/system details. Normally coin operated at that point as matrix once said.

    As stated before, we do have a "ball in the wall" visual indicator in the project. At design time we picked one that was also supposed to have an electrical contact that we intended to use to provide a audible indication and an input to the controller as well. Apparently not enough people bought that model, and they only offer the strictly mechanical ones now, so we will use a mechanical one, plus some other means to monitor room pressurization.
