Overview
The YCQB02L28 is a high-performance piezoresistive pressure transducer designed for professional HVAC, refrigeration and heat pump system applications. Powered by 5V excitation voltage, it converts medium pressure changes into standard 0.5-3.5V linear voltage output signals without additional signal amplification equipment. Featuring high measurement accuracy, excellent temperature resistance and long-term operational stability, this sensor supports real-time pressure detection and closed-loop control of fluid systems. It effectively monitors system operating pressure, prevents overpressure and underpressure faults, and ensures the safe, efficient and stable operation of HVAC and thermal management systems in various working conditions.
