SENSORS

Delphi Fluid Temperature Sensors
Delphi Fluid Temperature Sensors are continuous function
devices that change resistance inversely to temperature. They
measure the temperature of oil, fuel, water or engine coolant and
provide a signal to the powertrain control module. These brass
sensors consist of four major components:
•
•
•
•

Brass shell
Thermal grease
Gasket
Insert molded connector

The shell uses customized thread and hex sizes per application
requirements and the connector contains a Negative Temperature
Coefficient (NTC) thermistor with a crimpless conductive path.

Benefits
•
•
•
•
•

Simple design with few components for cost-effective,
lightweight package
Delphi Fluid Temperature Sensors
Design flexibility with customized mounting features, sealing
options, connection systems, and resistance output
Crimpless conductive path eliminates an electrical interface
100 percent resistance calibration verification helps ensure quality and reliability
Packaging variations include a dual coolant (coolant and gauge sensors), a right angle connection, and a reduced
size for small engine applications
