What advantages do our temperature sensors offer?

Infrared temperature sensors offer several advantages over conventional temperature sensors, especially in situations where non-contact temperature measurement is required. These include, among others:

  • Non-contact measurement: Infrared temperature sensors allow temperature measurement of objects without having to physically touch them. This is particularly useful in situations where direct contact with the object is not possible or desirable, such as hot, moving or hazardous surfaces.
  • Fast measurements: Infrared temperature sensors typically provide instant measurement results, making them ideal for applications that require a quick response, such as monitoring production processes or diagnosing problems in electronics.
  • Remote measurement: These sensors can measure temperatures remotely, often from a distance of several metres to a few kilometres, depending on the sensor type and performance. This makes them well suited for applications where access to the object to be measured is restricted or where there are safety risks.
  • Versatility: Infrared temperature sensors can be used in a variety of environments and applications.
  • High accuracy: Modern infrared temperature sensors offer high measurement accuracy and reliability, especially when measuring surface temperatures
  • Non-invasive measurement: As infrared temperature sensors measure temperature without contact, they cannot affect the integrity or surface finish of the object being measured. This is important in applications where the surface of the object must not be damaged, such as with sensitive materials or in medicine.

Possible applications for temperature sensors

Infrared temperature sensors offer an efficient, reliable and versatile method of non-contact temperature measurement that can be used in a variety of applications to optimise processes, improve product quality and comply with safety standards. These include

  • Food industry: Temperature control in cooking, refrigeration and preservation processes;
  • Pharmaceuticals: Temperature measurement in the manufacture of drugs and biological products;
  • Air Conditioning and Heating: Temperature control in air conditioning and heating systems;
  • Electronics: Temperature monitoring in electronic components to prevent overheating;
  • Scientific Research: Used in laboratories to measure temperature for experiments and research.

Temperature sensors: heat measurement

Temperature sensors are used to measure temperature using a variety of techniques. They can measure the temperature of an object precisely and remotely by detecting infrared radiation. The higher the temperature, the more thermal energy the object emits. These sensors can be used for a wide range of applications, such as dryers, furnaces or in the metal and glass industries. These sensors can withstand extreme temperatures. Fiber optic temperature sensors use WLPI or GaAs technology, and are used in a very wide range of applications. They can be used at cryogenic temperatures of up to 350°C.

  • Reactivity
    They enable rapid temperature measurement, which is crucial for real-time process control.
  • Reliability
    Temperature sensors are designed to be durable and reliable, even in demanding environments.
  • Versatility
    They can be used to measure the temperature of a variety of substances, from liquids to gases and solids.

The solution also includes an accelerometer for measuring vibration and motion, and a HAL sensor for detecting the proximity of a magnet, making it a complete platform for a wide range of use cases. The solution is battery-powered, water and dust resistant.

Althen Sensors gives you the power to measure and monitor temperature with unrivalled accuracy. Our IoT temperature sensors revolutionize real-time data collection, enabling you to make informed decisions to improve the efficiency, quality and safety of your operations.

What types of temperature sensors are available?

Thermocouples

Thermocouples consist of two different metals that are joined together. When the temperature at the junction changes, this creates a voltage that can be measured. Thermocouples are widely used and are well suited to high temperatures and harsh environments.

Infrared temperature sensors (infrared thermometers)

These sensors are based on laser technology and measure the infrared radiation emitted by an object to determine its surface temperature without contact. They are useful when the measurement of surface temperatures without direct contact is required, e.g. in industrial processes, medicine or food processing.

Fibre optic temperature sensors

Fibre optic temperature sensors use optical fibres to measure temperature changes. They offer the advantage that they are electrically insulated, robust and can be used in environments where conventional electronic sensors cannot be used due to electromagnetic interference, high voltage or high temperatures. Fibre optic probe: The core of a fibre optic cable consists of a material with a specific refractive index that enables light conductivity. One or more fibres are used as sensor probes to measure the temperature. The temperature measurement is based on a change in the refractive index or a change in the optical properties of the material in the fibre in response to temperature changes. They are used in areas such as power generation, industrial automation, aerospace, medicine and environmental monitoring.

Hand-held temperature measuring devices

Hand-held infrared temperature measuring devices (temperature measuring devices) are compact, portable devices that have been developed to measure temperatures quickly and easily. The temperature of an object or surface is determined by measuring the infrared radiation emitted by it. These allow the surface temperature of objects to be measured without direct contact, which is useful for measuring hot or moving material or in situations where contact with the object to be measured is undesirable. The sensor has a lens that is aimed at the object to be measured and a detector that receives the infrared radiation and converts it into a temperature reading. The devices are easy to use and generally provide quick measurement results that are nevertheless very accurate and reliable. Handheld infrared temperature measuring devices are versatile and can be used to measure temperatures in a variety of environments and applications, including industrial, laboratory, food processing, healthcare, air conditioning, heating, ventilation and many more.
