Product Specifications

• OEM Part Number: 125-9859, 1259895 (100% interchangeable with genuine parts)
• Product Type: Pressure Transmitter / Pressure Sensor for Construction Machinery
• Rated Voltage: 24.5V DC (compatible with 24V on-board circuit of construction machinery)
• Structure Features:
  • Standard threaded mounting stud + hex lock nut, easy installation, excellent sealing performance
  • Galvanized metal valve body + high-strength engineering plastic sheath, corrosion-resistant, high pressure resistant, vibration-resistant
  • Waterproof electrical connector, dust-proof, waterproof and oil-resistant, compatible with on-board circuits
  • Built-in high-precision pressure sensing chip, sensitive response and strong anti-interference ability
• Applicable Models: Caterpillar full-series excavators, loaders, graders, generator sets and other construction machinery (such as 3126, C7, C9 series engines)
• Working Principle: Pressure pushes the sensing diaphragm to deform, converts pressure into linear electrical signals through piezoresistive effect, and the ECU calculates the real-time pressure through the signal
• Installation: Directly screw into the corresponding mounting hole of the engine/hydraulic system, standard connector for plug-and-play use
