Infrared Sensors, Portable Infrared Thermometers and Hand Held Infrared Guns

An infrared temperature sensor works by detecting the infrared radiation emitted by an object. Every object emits infrared radiation as a function of its temperature. The sensor captures this radiation and converts it into an electrical signal, which is then processed to determine the temperature of the object. The key components of an infrared temperature sensor include an optical system to focus the infrared radiation onto a detector, a detector to measure the radiation, and an electronics unit to convert the detector’s output into a temperature reading.

• Non-contact Measurement: Infrared sensors measure temperature without needing to touch the object, making them ideal for moving or hot objects.
• Fast Response Time: They provide quick temperature readings, which is beneficial for dynamic processes.
• Safety: They allow temperature measurement from a distance, which is safer in hazardous environments.
• Versatility: Useful in a wide range of applications, from industrial processes to food safety.
• Hygiene: Ideal for situations where cleanliness is crucial, such as in the food and pharmaceutical industries.

Infrared temperature sensors can measure a wide range of temperatures, typically from -50°C to 3000°C, depending on the model and the application.

Emissivity is a measure of an object’s ability to emit infrared energy compared to a perfect blackbody. It ranges from 0 to 1, where 1 represents a perfect emitter. Emissivity is crucial because it affects the accuracy of infrared temperature measurements. Different materials have different emissivity’s, so the sensor must be configured to the correct emissivity value of the object being measured to obtain accurate readings.

Yes, infrared temperature sensors can be used for continuous monitoring. They are often integrated into industrial processes to provide ongoing temperature data, which is essential for quality control, safety, and efficiency

Yes, infrared temperature sensors can be integrated into existing systems. They are available with various output options, such as analog signals, digital outputs, and communication interfaces (e.g., RS485, Modbus), making them compatible with different control and monitoring systems.

Yes, like all measurement devices, infrared temperature sensors require periodic calibration to ensure accuracy. Calibration involves comparing the sensor’s readings with a known standard and adjusting the sensor as needed to correct any discrepancies. This process accounts for factors like emissivity and environmental conditions that can affect the sensor’s performance. Our expert NATA-accredited calibration team can do this.
