Product Internal Structure and Material Composition:
1. Forged Brass Pressure-Sensing Base (Media Inlet Body)
Forged as a single unit; features a 1/8″ NPT threaded connection to the refrigerant line. It transmits pressure to the internal isolation diaphragm and withstands pressures up to 34 bar without deformation.
2. Welded 316L Stainless Steel Isolation Diaphragm (Isolation Core)
An ultra-thin, fully welded diaphragm that completely separates the refrigerant medium from the damping silicone oil. It ensures lossless pressure transmission while preventing impurities and high temperatures from reaching the internal electronic chip.
3. Refrigerant-Resistant Damping Silicone Oil (Vibration Damping Medium)
Fills the sealed cavity behind the diaphragm; smoothly absorbs pressure pulses and isolates system vibrations to ensure stable readings.
4. High-Precision Piezoresistive Sensor Chip (Signal Acquisition Core)
Detects pressure-induced deformation transmitted via the silicone oil and converts it into a standard linear voltage signal; features built-in temperature drift compensation algorithms.
5. Green IP65 Waterproof 3-Pin Wiring Connector
Utilizes flame-retardant, oil-resistant cabling and a solder-free, quick-connect design for convenient on-site installation and removal; provides protection against dust, water, and condensation.

Core Product Features:
1. Precise, Real-Time Low-Pressure Monitoring (Core Function)
Continuously collects suction-side low-pressure signals and transmits them to the main controller; serves as the primary basis for electronic expansion valve flow regulation and compressor load control, stabilizing unit superheat and preventing liquid hammer in the compressor.
2. Multiple Low-Pressure Safety Interlock Protections
Excessively low pressure: Triggers anti-freeze protection, reducing main unit load or shutting down the system to prevent evaporator freezing and cracking;
Sudden pressure anomalies: Main controller detects system leaks or blockages, issues a pop-up fault alarm, and locks out compressor operation.
3. Silicone Oil Isolation & Vibration Damping (Eliminates Signal Jitter/False Alarms)
Features a composite diaphragm and silicone oil buffer structure that dampens compressor vibrations and pipeline pressure spikes; ensures stable pressure readings on the touchscreen and prevents frequent, random shutdowns caused by low-pressure protection.
4. Wide-Range Automatic Temperature Compensation (Stable Control Accuracy Year-Round)
Built-in temperature compensation circuitry ensures constant pressure measurement accuracy across the entire operating range—from -40°C cold starts to 120°C high-temperature full-load operation—maintaining consistent energy efficiency throughout the seasons.
5. Standardized Quick-Connect Fitting (Simplified Maintenance & Replacement)
No wiring or welding required; simply unplug the harness and unscrew the threaded base for complete unit replacement. A single technician can complete the repair in 5 minutes, significantly reducing downtime.
6. Optimized for R410A Refrigerant & High-Pressure Air-Cooled Units
Diaphragms, seals, and silicone oil are all optimized for high-pressure R410A refrigerant; prevents material swelling or diaphragm deformation/failure, ensuring compatibility with air-cooled heat pumps in both heating and cooling modes.
