UMA Pressure Senders & Temperature Probes


1/8 NPTF with mounting thread

1/8 NPTM

UMA is happy to announce that it’s line of precision electronic pressure senders has received TSO approval from the FAA. These units are the most economical TSO’d units on the market. They feature precision, solid state sensors and circuitry to give unequalled performance for the money. Available in gauge, differential and absolute types, they are compatible with avgas, jet fuel, engine oil and many other fluids. Because they have internal voltage regulation, they are compatible with indicating instruments that do not have precision output voltages. Units for fuel and oil pressure are certified under TSO C47. Units for manifold pressure are under TSO C45a.
