FAE 34470 Coolant Temperature Sensor

FAE 34470 Coolant Temperature Sensor

The FAE 34470 Coolant Temperature Sensor is a precision instrument designed to monitor the temperature of engine coolant in automotive and industrial applications. It delivers accurate, real‑time data that helps maintain optimal operating conditions, prevent overheating, and ensure reliable performance.

Key Functionalities

• High Accuracy: Measures coolant temperature with a tolerance of ±1 °C across the full operating range.
• Wide Temperature Range: Operates effectively from –40 °C to +120 °C, covering most automotive and industrial environments.
• Fast Response Time: Provides instantaneous readings with a response time of less than 0.5 seconds.
• Robust Construction: Encased in a durable housing that resists vibration, corrosion, and high temperatures.
• Standardized Output: Offers both analog (4–20 mA) and digital (PWM/ISO 9141) signal options for seamless integration with existing control systems.

Design Features

The sensor’s design incorporates several engineering choices that enhance reliability and ease of installation:

• Compact Form Factor: Dimensions of 30 mm × 15 mm × 10 mm allow placement in tight engine bay spaces.
• Threaded Mounting Interface: Standard M5 threading ensures quick, secure attachment to coolant lines or sensor brackets.
• High‑Temperature Sealant: Uses a silicone gasket that maintains integrity up to 150 °C.
• Low Power Consumption: Consumes less than 0.5 W, minimizing load on vehicle electrical systems.

Applications

The FAE 34470 is suitable for a wide range of vehicles and machinery, including but not limited to:

• Passenger cars and light trucks with conventional cooling systems.
• Heavy‑duty commercial vehicles requiring precise temperature monitoring.
• Industrial pumps, generators, and HVAC units where coolant temperature control is critical.

Installation Guidelines

1. Select the correct mounting location: Choose a spot on the coolant circuit that reflects the overall engine temperature (typically near the thermostat housing or radiator inlet).
2. Prepare the surface: Clean the area with isopropyl alcohol to remove oil, dirt, and debris.
3. Attach the sensor: Screw the sensor into place using a torque wrench set to 10 Nm to avoid over‑tightening.
4. Connect wiring: Route cables away from moving parts and high‑heat zones; secure with zip ties.
5. Verify signal integrity: Use a multimeter or diagnostic tool to confirm correct voltage/current output before finalizing the installation.

Calibration and Maintenance

To ensure ongoing accuracy, perform periodic calibration checks using a calibrated temperature bath. The sensor’s sealed construction typically requires no routine maintenance; however, inspect for physical damage or corrosion after extended operation in harsh environments.

Benefits of Choosing the FAE 34470

• Reliability: Proven performance in demanding automotive and industrial settings.
• Versatility: Compatible with a variety of control systems and vehicle models.
• Cost‑Effective: Long service life reduces replacement frequency and maintenance costs.
• Ease of Integration: Standardized outputs simplify wiring and software configuration.

Technical Specifications Summary

The FAE 34470 Coolant Temperature Sensor stands out as a dependable, high‑performance component for anyone needing precise coolant temperature monitoring. Its robust design, wide applicability, and straightforward installation make it an excellent choice for both new builds and aftermarket upgrades.
