New Products: Refrigeration pressure sensors

The P528 family of ceramic capacitiverefrigeration pressure sensors target high volume applications requiring ±2% or better accuracy over the normal –40 to 85°C operating temperatures, such as those in refrigeration compressors, rooftop chillers, and refrigerant recovery systems.

The rugged sensors withstand high overpressure spikes, come in 0-to-15 to 0-to-500-psia pressure ranges, are powered by a regulated 5-V power supply that produces a standard 0.5 to 4.5-V ratiometric output, are temperature compensated, have EMI/RFI and ESD protection, and output signal stability. Available pressure ports / -27 NPT, ¼-18 NPT, and ¼ SAE female threads with Shrader deflators. The sensors have an integral Packard Metri-Pak 150 electrical connector.
