An infrared temperature sensor allows for precise, non-contact temperature readings in industrial and machinery settings. These devices measure thermal radiation to determine surface temperature from a safe distance, ideal for monitoring moving parts, high-temperature processes, or hard-to-reach equipment. This method avoids product contamination and sensor damage.
Compel offers a focused selection of infrared temperature instruments for professional trades. Our range includes handheld digital infrared thermometers for diagnostics and maintenance, as well as industrial infrared temperature sensors with 4-20mA outputs for integration into process control systems. Find reliable tools for accurate non-contact temperature measurement.

Handheld Thermometer vs. Fixed-Mount Sensor
Your first decision is how the device will be used. Handheld infrared thermometers are portable tools for spot checks, diagnostics, and preventive maintenance. They are useful for quickly assessing the temperature of motors, circuit breakers, and HVAC systems. Some models include a laser pointer for precise aiming or a hygrometer to measure humidity.
A fixed-mount industrial infrared temperature sensor is designed for permanent installation. It provides continuous, real-time data for process control and automation. These sensors typically feature a standard 4-20mA output signal, allowing them to connect directly to PLCs, data loggers, and control panels for automated monitoring and system adjustments.
Key Specifications for a Non Contact Temperature Sensor
Verify that the sensor's temperature range covers your application's requirements. The instruments available cover a common industrial range from -50°C to 800°C. Ensure your minimum and maximum process temperatures fall comfortably within this scope.
For fixed sensors, the output signal is a primary concern for system compatibility. A 4-20mA analog output is an industry standard that is resistant to electrical noise over long cable runs, making it suitable for most industrial control systems.
Another factor is emissivity, which is a material's ability to emit thermal energy. Different materials have different emissivity values. For accurate readings, the sensor must be set to match the target material's emissivity. Check the product datasheet for information on adjustable emissivity settings.

Choosing Infrared Temperature
- What is the difference between a handheld IR thermometer and a fixed infrared temperature sensor?
- A handheld thermometer is a portable device used for manual spot checks and diagnostics. A fixed infrared temperature sensor is permanently installed to provide continuous, automated temperature monitoring as part of a larger control system, often using a 4-20mA output.
- Is a temperature range of -50°C to 800°C sufficient for most industrial tasks?
- This range covers many common industrial applications, including monitoring motors, bearings, electrical panels, and certain manufacturing processes. However, you must confirm your specific process temperatures to ensure they fall within this operating window.
- What does a 4-20mA output on an infrared temperature sensor mean?
- A 4-20mA output is a standard analog signal used in industrial automation. It allows the sensor to transmit temperature data reliably over long distances to a PLC, DCS, or other control device for process monitoring and control.
- Can I use a non contact temperature sensor on a shiny metal surface?
- Shiny, reflective surfaces have low emissivity, which can cause inaccurate readings. For best results, use a sensor with adjustable emissivity settings or apply a non-reflective coating, like high-temperature paint or electrical tape, to the target area.
- Why is my infrared temperature reading incorrect?
- Common sources of error include an incorrect emissivity setting for the target material, or the target being smaller than the sensor's measurement spot size (distance-to-spot ratio). Obstructions like steam, dust, or dirty lenses can also affect accuracy.
- Are these infrared temperature sensors rated for hazardous locations?
- Suitability for hazardous environments requires specific certifications like ATEX or IECEx. Standard sensors are typically not rated for these areas. Always check the individual product datasheet to verify if a sensor holds the specific approvals required for your application.
