YCQB02L12 Heat Pump AC Refrigerant Pressure Sensor

      YCQB02L12 is a compact high-precision low-voltage output pressure transducer specially designed for full-range HVAC, heat pump and refrigeration systems. Powered by stable 5V DC, it converts low-pressure refrigerant medium 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 low-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
