Supporting Documentation (if available)

As HVAC/R systems shift to low GWP refrigerants, discharge temperatures rise sharply, creating more thermal and mechanical stress on pressure switches. HVAC/R systems need components that stay accurate and reliable despite heat and wide pressure ranges. The new PS80-L Low Thermal Drift Pressure Switch from Sensata solves this with best-in-class ultra-low thermal drift (±2%), hermetic sealing and IP67 protection. These features ensure stable performance in tough environments. Its compatibility with next generation low GWP refrigerants and flexible high pressure set point range improve system efficiency, safety, and regulatory readiness, enabling the sustainable OEM transition to A2L & A3 refrigerants.

Why it matters:
Low thermal drift ensures the switch maintains accurate actuation even when temperatures change dramatically. This means the system won’t trigger too early or too late because of heat or cold. As a result, customers get consistent performance, fewer false trips, and higher safety in demanding environments. And because the design stays mechanically and electrically compatible with existing pressure switches, it drops into current systems without redesign, reducing installation time and cost.

Why the PS80-L Low Thermal Drift Pressure Switch s a market innovation:
1. Ultra Low Thermal Drift (±2%) in Extreme Temperatures
Most electromechanical pressure switches suffer noticeable actuation drift when exposed to very hot or very cold environments. The PS80 L maintains less than ±2% drift, ensuring stable, accurate switching even under harsh thermal conditions. This level of stability is not common in traditional high pressure switches.
2. Maintains Full Mechanical & Electrical Reliability of PS80 High Pressure Switches
Many thermal compensated solutions require trade offs in durability or electrical performance. The PS80 L achieves high thermal stability without sacrificing robustness, giving customers high precision and proven long term reliability.
3. Drop In Compatibility (No System Redesign)
Unlike new to-market technologies that require changes in fittings, calibration, or wiring, the PS80 L is designed for seamless compatibility with existing PS80 installations—saving OEMs engineering time, recertification effort, and cost.
4. Designed for Next Generation Low GWP Refrigerants
Low GWP systems typically operate at higher discharge temperatures, which amplifies drift issues in conventional switches. The PS80 L’s stability and high temperature capability make it uniquely suited for new refrigerants like R32, R454A/B/C, and R290.
5. Future Ready Safety & Environmental Certifications
With IP67 sealing, hermetic construction, ignition protection (NCKL), and ATEX certification underway for early 2026, the PS80 L targets applications where safety and compliance are becoming stricter—differentiating it from many legacy switches.

The new Sensata Technologies PS80-L Low Thermal Drift Pressure Switch is a market innovation because it delivers high pressure electromechanical switching with extremely low thermal drift—something rare in the category—while remaining drop-in compatible, durable, and optimized for modern low GWP, high temperature systems.
