Types of Sensors We Offer

Besides keeping sensors in stock at many of our facilities, our convenient Parts.Cat.Com online store contains a full inventory of Cat sensors, from pressure to speed to timing sensors. We have sensors available for all models of Cat equipment, including trucks, generators and more. Cat sensors use top-quality materials and face strict testing to ensure consistent, long-lasting performance.

Liquid Level Sensors

Level sensors monitor the level of liquids in tanks and process systems. One of the most common tasks for these types of sensors is helping operators keep an eye on the fuel level.

Position Sensors

Position sensors typically measure the distance a body travels by noting its movement and translating its angular mechanical position to an electrical signal. Some position sensors can also identify an object’s absence or presence. The position sensors Caterpillar offers include options like:

• Medium and heavy-duty rotary sensors.
• Steering wheel positioning sensors.
• Cylinder position sensors.

Pressure Sensors

Pressure sensors measure the amount of pressure in a liquid or gas. Cat equipment uses these sensors in air systems, fuel systems, exhaust after-treatment systems, engine oil systems and other engine-related applications. Some of the specific types we offer are:

• High-pressure pulse width modulation (PWM) sensors.
• Connector pressure sensors.
• Wire-leaded pressure sensors.

Speed and Timing Sensors

Speed and timing sensors, also called crank or crankshaft position sensors, are among the vital parts your equipment’s engine relies on for input. Speed sensors often work by reading the teeth on the crankshaft as it turns to determine its rotation speed. Examples include:

• Low-speed timing sensors.
• High-accuracy timing sensors.
• Hail-effect active speed sensors.

Temperature Sensors

Cat temperature sensors use thermistors and thermocouples to sense temperature in your equipment’s vital operating systems. Temperature sensors are available as thermocouple output, passive resistive output and active PWM outputs. Some specific examples include:

• PWM temperature sensors.
• Passive temperature sensors.
• Active temperature sensors.
• PWM gas exhaust temperature sensors.
• Gas exhaust thermocouples.
