Product Overview

Accurate Temperature Monitoring for Engines

An Exhaust Gas Temperature (EGT) Sensor is designed to monitor the temperature of exhaust gases at a specified location within an engine exhaust system. It converts temperature changes into an electrical signal that can be interpreted by a compatible monitoring or engine control system.

Depending on the engine configuration, temperature measurements can support the monitoring of engine operating conditions and exhaust after-treatment systems. The exact sensor design and operating range depend on the intended application.

01
Exhaust Temperature Measurement

Measures exhaust gas temperature at the sensor's installed location.

02
Electrical Signal Output

Provides a temperature-related signal to a compatible monitoring or control system.

03
Application-Specific Design

Sensor specifications must match the engine and exhaust-system requirements.

Product Functions

The Role of an EGT Sensor

Exhaust temperature data helps compatible engine systems monitor thermal operating conditions.

01

Temperature Detection

Detects temperature at its installation point in the exhaust system and provides a corresponding electrical signal.

02

Thermal Condition Monitoring

Temperature information can help compatible control systems assess exhaust thermal conditions during engine operation.

03

Engine System Integration

Sensor type, signal characteristics, connector and installation requirements must match the specified engine system.

How It Works

From Heat Detection to Temperature Data

An EGT sensor is installed at a designated point in the exhaust system. Its sensing element responds to temperature changes and produces an electrical signal that the compatible system can interpret.

01

Exhaust Temperature Changes

Exhaust gas temperature varies with engine operating conditions and the location being measured.

02

The Sensor Detects Temperature

The sensing element responds to the temperature at its installed location.

03

The System Receives a Signal

A compatible control or monitoring system interprets the signal according to its calibration and design.

Application Overview

Temperature Monitoring for Exhaust Systems

Exhaust gas temperature sensors are used in suitable engine and exhaust-system configurations where temperature measurement is required. Their precise location and function depend on the vehicle and engine system design.
