Applications
sensata pressure 2cp50 71 42
Commercial HVAC Rooftop Units
Equipment Model: Carrier 30GT Series Rooftop Packaged Unit (cooling capacity: 5–25 tons, R454a refrigerant).
Installation Location: High-pressure refrigerant loop (between compressor discharge port and condenser inlet).
Functional Role: Monitors real-time discharge pressure (normal operating range: 250–550 psia). When pressure exceeds 580 psia (due to dirty condenser coils or refrigerant overcharge), the sensor triggers the unit’s “high-pressure protection” to unload the compressor, avoiding damage.
Supermarket Cascade Refrigeration
Equipment Model: Danfoss VLT Refrigeration Drive + Supermarket Cascade Refrigeration Rack (R454b refrigerant, for walk-in freezers and display cases).
Application Value: As a sealed gauge pressure sensor, it accurately measures the high-pressure side pressure of the cascade system (max 590 psia), coordinating with electronic expansion valves to maintain stable refrigerant flow, reducing energy consumption by ~8% compared to traditional pressure switches (based on HVAC industry efficiency data).
Industrial Factory HVAC Systems
Equipment Scenario: Large-scale factory assembly line HVAC (e.g., automotive manufacturing plants, with high electromagnetic interference from welding machines and conveyor motors).
Adaptation Advantage: The sensor’s 100 V/m EMC immunity prevents false signals caused by electromagnetic noise, ensuring stable control of the factory’s central air conditioning chilled water system (e.g., matching York YVAA series chillers for pressure feedback).
Compressor Discharge Monitoring
Serves as a critical feedback node for variable frequency drive (VFD) compressors, providing the real-time 10ms response data required to adjust motor speeds dynamically for load matching.

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.
