1. Product Overview

This industrial temperature sensor is a core replacement spare part specially developed for Gardner Denver / CompAir screw air compressors (TD series). It real-time monitors oil temperature and discharge air temperature inside the compressor host, transmits accurate temperature signals to the main controller, and triggers over-temperature alarm & automatic shutdown protection to avoid rotor burnout, oil carbonization and equipment breakdown caused by overheating

2. Core Technical Features

High Precision Sensing Chip Adopts industrial-grade thermistor sensing element, temperature measurement error ≤ ±0.5℃, fast response within 1 second, stable signal output under continuous heavy-load operation. It eliminates false alarms and signal drift issues of low-cost generic sensors.

Heavy-Duty Brass Probe & Housing The sensing probe and thread body are made of high-purity brass with excellent thermal conductivity, oil resistance and corrosion resistance. It can endure long-term exposure to compressor lubricant (6000FG industrial compressor oil) and high-temperature airflow without oxidation or leakageAlibaba.co....

Standard Integrated Connector & Sealed Cable Equipped with OEM-matching black waterproof plug, plug-and-play without wire modification. The matched high-temperature shielded cable resists electromagnetic interference from inverters and motors, suitable for dusty, high-vibration industrial workshops.

Perfect OEM Compatibility 1:1 identical size, thread specification and signal protocol as original Gardner Denver part. Direct replacement for original 89857539 sensor, no extra machining or adapter required, greatly shortening maintenance downtime.

Wide Working Temperature Range Normal working range: -40℃ ~ 150℃, fully covers the normal and alarm temperature interval of screw air compressors, reliable in all seasons and different working loads.
