DESCRIPTION

The P158-300A-C2A is a ceramic capacitive pressure transducer designed for high and low side pressure measurements in refrigeration systems, product refrigeration, refrigerant recovery, and transport refrigeration applications. It features a 0–300 PSI absolute measurement range with a 5.0 ± 5 V supply voltage, maximum supply current of 5 mA, and linear amplified output with ±0.5% linearity error and 15 ms response time to 63% of full scale. The transducer is temperature compensated with a total error band of 2.0% of span across the operating range of -30 °C to +100 °C, offers superior long-term stability (±0.5% over 1 year), and is housed in CA3600 brass with neoprene seal material suitable for R134a and other refrigerants. It withstands 10 million full pressure cycles, 10 g sinusoidal vibration (10–2000 Hz), 75 g shock, and includes over-voltage, reverse polarity, and short circuit protection, making it ideal for demanding refrigeration environments requiring reliable pressure monitoring.
