I have a customer who is looking for a pressure transducer for an R404A refrigerant system. He wants the range to be 30"Hg to 150PSIG and 30"Hg to 300PSIG for the two transducers.
30"Hg is way, way, way off my chart, and my chart stops at 6.8"Hg = -60 degrees F.
This system is designed with a suction temperature of 35 degrees. It will trip out before it gets much lower than that.
Our standard transducers are -14.5 to 116 PSIG and 0 to 435PSIG. But the customer still wants the transducer in his range.
I have googled for two hours and found nothing in his range. The only one that came close costs more than all the other electrical components on the unit combined.
Does anyone know of a transducer that will fit in his range?
I would appreciate any leads.
