We are working on a small volume product where we need to monitor the pressure of water. The problem is the sensor, cable, etc, needs to go into the hole. This seems the change the price radically, by a factor of 100 for stuff that we can find. For this reason, we have considered trying to just source PCB transducers and we will build the housing system. That is assuming affordable sensors cannot be found.
We need to read pressures to about 250psi at the very max, but typically only 100psi. I am curious if anyone knows where to shop for either the PCB unit, or complete sensor unit? Yes, places like Omega have them, but at prices that are beyond the entire budget for the sensor alone.
As for accuracy, really about 1% is more than fine for this. Any added resolution is great, but right now we are focused on price, and reliability as driving factors.
