I need a pressure switch for an electric circuit that has to be closed once a piston is compressing at a pressure of (approximately as we haven't specified how much force we have to use, and maybe it will be greater) 5 tons/cm^2 (75000 psi). The problem is that I can't find any model that satisfies these characteristics due to either
- them not being as common as to be talked about in the sites I can access
- my abilities at intelligent Google search are not good enough or
- them not existing.
I can't believe a component like that doesn't exist and I'm very confident about my intelligent Google search skills so, can someone tell me if there's a chance I can get to know about components like that?
I would be very thankful if anyone could give me a model or a brand or any reference or recommendation to find such information (or about why I won't).
