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. 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 Specifications for Fluid Temperature Sensor Thermal and Electrical Properties • • • • • • Typical voltage supply: 5 VDC Operating temperature: -40°C to 135°C Resistance at 25°C: 2795 ohms Thermal time constant: 15-24 sec. in silicone oil Accuracy (±°C) -40°C to 100°C: ±0.56 to 0.77°C Accuracy (±°C) 100°C to 150°C: ±0.77 to 1.24°C Mechanical Characteristics • • • • • • • • • Sensor housing material: Brass Sensor connector material: PBT 30% GF Thread size: M12 x 1.5; Hex size: 18.90 mm (3⁄4 in.) Thread size: 3⁄8 in. – 18 NPTF; Hex size: 18.90 mm (3⁄4 in.) Thread size: 1⁄2 in. – 14 PTF; Hex size: 22.22 mm (7⁄8 in.) Sealing washer (copper; for metric threads only): P⁄N 12146937 Suggested mating connector assembly: P⁄N 15336004 Installation torque: 20 Nm, dynamic Overall weight: 23.2 to 62.2 grams www.delphi.com | © Delphi.
