FAQ
2cp5 Pressure Transducer
What is the difference between the 2CP5 and 2CP50 series?
The primary difference lies in the pressure range. The 2CP5 is designed for applications up to 500 psi, while the 2CP50 series is utilized for pressures above 500 psi, extending up to 750 psi
Which refrigerants are compatible with the HNBR seal?
The HNBR (Hydrogenated Nitrile) seal is compatible with R134a, R404a, R407c, R410a, and R507. If you are using R12 or R22, Neoprene seals are generally recommended.
Does the sensor require a specific mating connector?
Yes, the 2CP50-71-1 typically utilizes a Packard Metri-Pack electrical connection, designed to mate with Packard connector #12065287 for a secure, IP65-rated seal.
What pressure port and connection materials are available, and do they match standard industrial fittings?
A: The pressure port is 1/4″ SAE female flare (with deflator) + 7/16″-20 UNF-2B. Connection materials include brass (2CP5-exclusive) or plated steel — aligned with common industrial fitting standards.
