Description
Product Overview
The YCUPONE A/C Refrigerant Pressure Sensor is a digital, non‑illuminated unit designed for automotive air‑conditioning systems. Measuring 4.72 x 4.72 x 0.47 inches and weighing just 2.82 ounces, it delivers precise pressure data with a ±1% accuracy range. Engineered for a maximum supply voltage of 12 V, the sensor operates reliably across a temperature span of 1 °C to 1 °C, making it suitable for both low‑ and high‑temperature environments. Its robust construction and compact footprint ensure easy integration into existing compressor assemblies.
Usage
This sensor is intended for use in automotive air‑conditioning and refrigeration circuits. It monitors refrigerant pressure to help maintain optimal cooling efficiency, prevent compressor overload, and alert users to potential leaks. Ideal for service technicians, DIY enthusiasts, and fleet maintenance teams, the sensor fits standard compressor models that use part numbers 5019881AB, 5174039AA, or 5174039AB. Ensure the vehicle’s electrical system provides a stable 12 V supply for accurate readings.
