Replacement Pressure Sensors for Heavy Equipment

Find heavy equipment pressure sensors at Fab Heavy Parts for selected excavators, diesel engines, industrial air compressors, and other machinery. Our collection includes replacement pressure sensors, oil pressure sensors, fuel pressure sensors, pressure switches, and pressure transducers for different equipment systems.

Pressure sensors provide information used to monitor operating conditions in specific circuits. Because sensors are designed for different applications, choosing the correct replacement requires more than matching the equipment brand or the sensor's appearance.

Pressure Sensors for Excavators and Diesel Engines

Browse pressure sensors listed for selected Caterpillar, Hitachi, Volvo, John Deere, Isuzu, and other equipment applications.

For Caterpillar equipment, available listings include pressure sensor 239-2395 for specified engine and machine applications, as well as oil pressure sensor 161-1704 for selected excavators.

The collection also includes pressure sensor switch 4436536 for Hitachi ZX-series excavators and sensor 4436535 for selected John Deere excavators, including the 130G and 210G.

For Volvo excavators, pressure sensor VOE17235200 is listed for selected EC-series models, including the EC140E, EC220E, EC250E, and EC300E. Additional products include fuel pressure sensors for specified Isuzu diesel engine applications.

These examples refer to individual product listings, not universal compatibility across every machine or engine version.

Air Compressor Pressure Sensors and Transducers

Our collection also includes replacement pressure sensors for selected Atlas Copco and Ingersoll Rand air compressors.

Available products include Atlas Copco pressure sensor 1089049238 and Ingersoll Rand pressure transducer 39853791. These components are listed for particular compressor applications and may differ from pressure sensors used in excavator hydraulic or engine systems.

Some listings in this collection are temperature sensors rather than pressure sensors. Always confirm the component's function before ordering.

How to Choose the Correct Pressure Sensor

Start by checking the original sensor's complete part number and identifying the system in which it is installed.

Compare the replacement's intended application, electrical connector, mounting thread, and pressure or signal specifications where these details are available. Your equipment or engine model and serial number may also be needed to verify compatibility.

If you are investigating an electrical fault, explore our wiring harness collection for related replacement components.

Review the individual product descriptions and listed applications to identify a suitable pressure sensor for your equipment.

Frequently Asked Questions

How do I know which pressure sensor fits my excavator or engine?

Start by identifying the original sensor's part number, along with your equipment or engine make, model, and serial number. Check whether you need an oil, fuel, hydraulic, or another type of pressure sensor. Compare the replacement sensor listing's application, electrical connector, and mounting details. Equipment model information alone may not be enough to confirm compatibility.

Can I use an oil pressure sensor to replace a hydraulic or fuel pressure sensor?

Not unless the replacement is specifically documented as compatible with that application. Oil, hydraulic, and fuel pressure sensors can have different pressure ranges, electrical outputs, connectors, and mounting requirements. We recommend matching the original part number and verifying the sensor's intended function before ordering.

Can you help me identify a replacement pressure sensor if the original part number is unreadable?

You can provide your equipment or engine model, serial number, and clear photographs of the original sensor. Photos showing its connector, mounting thread, and installation location may help narrow down the options. If available, information about the monitored system and any fault codes can also be useful. Additional technical details may still be required to confirm the correct replacement.

What should I check before installing my replacement pressure sensor?

Before installation, compare the replacement with the original component, including its part number, connector, mounting arrangement, and specified application. Inspect the replacement for visible damage and follow the equipment manufacturer's service procedures. Pressure-containing systems may require specific shutdown, isolation, and depressurization precautions before a sensor can be safely removed.

Why is my equipment still showing a pressure warning after I replace the sensor?

A pressure warning does not always mean the sensor is faulty. Possible causes include an actual pressure problem, damaged wiring, poor electrical connections, an incorrect replacement sensor, or another system fault. Confirm that the installed sensor matches the application and have the affected system diagnosed according to the manufacturer's service information. Do not ignore a warning that may indicate an unsafe operating condition.
