YCQB02H01 Heat Pump AC Refrigerant Pressure Sensor

        YCQB02H01 is a compact high-precision voltage output pressure transducer specially developed for full-range HVAC, heat pump and refrigeration systems. Powered by stable 5V DC, it converts refrigerant medium pressure into linear 0.5-3.5V analog signal without extra signal amplification modules, compatible with mainstream HFC, HCFC refrigerants such as R410A, R134a, R22. Equipped with 1/4 standard solder interface and integrated 2-meter wiring harness, IP67 waterproof shell and wide operating temperature range, this sensor realizes continuous real-time pressure sampling, overpressure early warning and automatic load adjustment for HVAC systems, effectively improving the operating stability, safety and energy-saving performance of air conditioning, chiller and cold storage equipment.

• Measuring range: 0 ~ 2 Mpa, measurement accuracy ±2% FS
• 5V DC power supply, linear 0.5-3.5V analog signal output
• 1/4 standard solder connection, equipped with 2-meter integrated lead wire
• IP67 waterproof housing, working temperature -30℃ ~ +80℃
