About products and suppliers

Infrared temperature sensors help in measuring object temperatures. Temperature measurement instruments either be contact or non-contact types.

Non Contact type

An infrared temp sensor is used in contact-type devices. Some examples of these non contact temperature sensors include the IR non contact thermometer and an IR pyrometer. If a laser is used, it is referred to as a laser temperature sensor. If high temperatures or moving parts have to be measured, then an infrared thermocouple is used.

Contact type

Contact sensors are used through physical contact with the measuring device by placing the sensor on the object's body to measure the object’s temperature. Semiconductor temperature sensors, thermocouples, thermistors, and resistance temperature detectors (RTDs) are used in the contact types.

What is an infrared temperature sensor?

The infrared (IR) temperature sensor helps to measure the amount of infrared energy that an object emits so that the temperature of the object can be adequately determined. To describe the infrared temperature sensor straightforwardly, the device is used by pointing it at the object, pressing the button on it, and reading the temperature. Examples of these infrared temperature gauge devices include infrared thermometers, infrared pyrometers, etc.

Differences between an infrared pyrometer and an infrared thermometer

An infrared pyrometer, otherwise referred to as an IR pyrometer, is a type of IR temp sensor that is used to measure the temperature of distant objects. It is a different class of thermometers that is used for measuring only high temperatures. However, today it has been modified to measure low temperatures as well.

IR thermometer is a type of IR temperature sensor that is used to measure the temperature of a subject. An example is mlx90614.

The fundamental difference between an infrared thermometer and an infrared pyrometer is that a thermometer measures temperature, while a pyrometer is a remote-sensing thermometer that is specifically suited to gauge high temperatures.
