Exhaust and Gas Temperature sensors from Variohm are rich in pedigree for motorsports success and with a strong reputation for high reliability and durability across a broad spectrum of applications for exhaust gas monitoring. The EGT exhaust gas temperature sensors are based around a type K thermocouple in a robust design which has been well proven in motorsport and similar demanding environments. In additional to the standard product lines, a wide range of customized materials and probe designs are available.

Exhaust Gas Temperature (EGT) sensors are essential components used to measure the temperature of exhaust gases in internal combustion engines. These sensors provide critical data that helps optimize fuel combustion, improve engine efficiency, and prevent potential damage from excessive temperatures. The need for EGT sensors arises primarily in high-performance and motorsports applications, where precise engine monitoring is crucial. Additionally, they play a role in industrial and heavy-duty vehicle applications to enhance fuel efficiency and emission control.
Variohm EuroSensor, a leader in sensor technology, offers a comprehensive range of high-reliability EGT sensors designed for demanding environments. In Israel, these sensors are distributed by Amironic, ensuring local availability and technical support.
Functionality and Design
Variohm’s EGT sensors are built around a Type K thermocouple, a well-established technology for high-temperature measurement. The thermocouple generates a voltage corresponding to the exhaust gas temperature, which is then interpreted by an engine control unit (ECU) or data acquisition system.
Key features of these sensors include:
- Robust construction: Designed to withstand extreme conditions.
- Wide temperature range: Suitable for temperatures up to 1300°C.
- Material options: Stainless steel (316) or Inconel for enhanced durability.
- Multiple probe configurations: Available with different probe diameters, tip types, and mounting options.
- Compatibility with various fuels: Suitable for gasoline, alcohol, nitro methane, sulphur, and corrosive fuels.

Installation Instructions
Proper installation is critical for accurate temperature readings and sensor longevity. Follow these steps:
- Select Mounting Location: Position the sensor in the exhaust manifold or downpipe, ensuring it is placed before the catalytic converter for accurate readings.
- Drill the Mounting Hole: Use a drill bit matching the required probe diameter.
- Install the Compression Fitting: If applicable, weld the bung to the exhaust pipe and insert the sensor.
- Secure the Sensor: Tighten the compression fitting or mounting hardware to avoid leaks and movement.
- Connect the Wiring: Ensure correct polarity when connecting to the data acquisition system or ECU.
- Test the Sensor: Validate operation by running the engine and verifying real-time data.
Operating Guidelines
- Ensure Proper Grounding: Grounding the sensor correctly reduces electrical noise and improves accuracy.
- Avoid Overheating: Exceeding the specified temperature range can degrade sensor performance.
- Periodic Maintenance: Inspect for wear and contamination, especially in high-performance applications.
