WNK81ma
WNK
The WNK80MA is a high-performance vacuum oil pressure sensor optimized for hydraulic applications, leveraging dry ceramic capacitive sensor cores and ASIC signal conditioning. Its 4-20mA output (compatible with 0.5-4.5V/1-5V/0-10V/I2C) and 1/4-1/8 NPT fittings make it a plug-and-play solution for hydraulic systems, compressors, and refrigeration units. Built to resist corrosion, wear, and vibration, it’s engineered to prevent hydraulic system failures caused by inaccurate vacuum pressure monitoring.
Hydraulic systems and compressors depend on precise vacuum pressure control to avoid leaks, component damage, and energy waste. The WNK80MA solves these issues:
Hydraulic cylinders (e.g., in construction machinery) require tight vacuum seals to maintain force. The WNK80MA’s 0.5% F.S. accuracy detects even minor vacuum leaks early, preventing cylinder drift and costly downtime.
Compressors (the “heart of refrigeration systems”) need accurate pressure data to balance compression ratios. The WNK80MA measures vacuum pressure in low-pressure refrigerant lines, ensuring the compression cycle (compression → condensation → expansion → evaporation) runs efficiently—reducing energy consumption by up to 15%.
Most hydraulic and refrigeration equipment uses 1/4 or 1/8 NPT threads. The WNK80MA’s pre-configured NPT fittings eliminate the need for adapters, cutting installation time by 30% and reducing leak risks from mismatched parts.
Vacuum & Pressure Versatility: Handles 0-60bar to -1-700bar, supporting gauge, absolute, and sealing pressure for hydraulic and refrigeration needs.
Ceramic Sensor Core: Dry ceramic technology resists oil contamination (common in hydraulics) and delivers faster response times (≤5ms) than silicon cores.
IP65 Protection: Dust-tight and water-resistant, making it suitable for outdoor hydraulic equipment (e.g., excavators) or damp refrigeration rooms.
Quality Testing: Every WNK80MA undergoes 48-hour aging tests and temperature compensation to ensure reliability in harsh conditions.
Technical Expertise: Our team provides guidance on integrating the sensor with hydraulic control systems (e.g., PLCs) and troubleshooting vacuum pressure anomalies.
Warranty & Shipping: 12-month warranty; small orders ship via DHL/FedEx (4-5 business days), while large orders use sea freight for cost savings.
Customization: Options include custom thread sizes (e.g., 7/16-20UNF female) and logo printing for brand alignment.
