Since you would typically be monitoring this with some sort of PLC, you might see this done at line voltage (120 VAC in the US) or more commonly now using dedicated DC devices operating at 24V. With all of the push to redundant safety devices, 24VDC is becoming the most common.

I'd use enough, but not too much, for the application at hand.
