A high-quality hydraulic oil temperature sensor. Its function is to accurately measure the oil temperature in the system and transmit this information to the gauge on the operator's dashboard or the machine's control system. It is a key component of the early warning system against hydraulic system overheating, which protects the pump and valves from serious and costly failure.
GX-AFTER is the smart choice for your machine. We provide high-class replacement parts that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

The list above is for reference. Before purchasing, we recommend a visual comparison with your old part.
Before replacing any hydraulic system components, you must completely depressurize the system by lowering all attachments to the ground and operating all levers with the engine off. Hot hydraulic oil can cause severe burns. Use safety glasses and gloves.
Replacing the sensor is a perfect opportunity to check the condition of the hydraulic oil and filter. Contaminated oil is the most common cause of system failure. Use high-quality HYPTRON hydraulic oil and change filters to proven REDX brand replacements to ensure the long and trouble-free operation of the entire system.
The hydraulic oil temperature sensor is a key component of the hydraulic system's protection. Its failure can lead to a lack of information about the oil overheating, resulting in a loss of its lubricating properties, damage to seals, and seizure of the hydraulic pump.
A faulty sensor risks hydraulic pump seizure.
The cost of replacing a sensor is negligible compared to an overhaul of the entire hydraulic system. Protect your machine from the worst-case scenario – order a new GX-AFTER sensor today and be sure you will always know about a problem in time.

In most cases, yes. However, the cause could also be a damaged electrical wire, connector, or the gauge itself on the dashboard. It is worth checking the circuit for continuity before replacement.
2. How can I test if my old sensor is faulty?You can do this with a multimeter by measuring the sensor's resistance at different temperatures (e.g., in cold and hot oil). The resistance should change smoothly. If there is no change or the circuit is open, the sensor is faulty.
3. What are the different types of temperature sensors in machinery?Construction machines primarily use thermocouples and Resistance Temperature Detectors (RTDs) for their durability. Thermocouples offer faster response times, while RTDs provide higher accuracy. Thermistors are used for their small size. There are also Infrared (IR) sensors for non-contact temperature measurement.
