Infrared pyrometers are indispensable for efficient temperature control and monitoring in many industrial applications. They consist of a temperature sensor attached to an infrared port on a heating device or other measuring instrument. The infrared port is usually connected to a digital microcomputer or a digital circuit board. The microcomputer then interprets the signals from the infrared sensor to calculate the actual temperature. The infrared sensor is used for temperature measurement in the air, gas volume meter, or liquid medium. The IR sensor is attached to the surface of the heating device or other measuring instrument and is in direct contact with the medium.
The principle that gives rise to this form of the sensor is the absorption of infrared radiation by certain substances in the medium. The substances then emit infrared radiation of wavelengths that vary according to the concentration of the substance. The high temperature pyrometer is a versatile, cost-effective solution for measuring the temperature of various materials, including metals and semiconductors. It can handle a wide range of temperatures from -40°C to 3200°C over a very fast response time. It is ideal for use in applications where a uniform temperature is required. It has a fixed-needle sensor that can detect even low levels of heat in air or liquids.
What are the benefits of using high temperature pyrometer?
- Non-contact infrared pyrometers use a lens to concentrate the IR energy onto the measurement surface. Therefore, there is no physical contact between the sensor and the surface. This makes the non-contact infrared systems ideal for applications where physical contact may cause damage to the surface of measurement, such as with paper, plastics or other delicate materials.
- Non-contact infrared pyrometers can continuously monitor product temperature in a manufacturing facility and can be programmed to alert operators when the desired range is exceeded. They can provide a complete thermal profile of a process by measuring both product and air temperature, offering a complete view of process performance.
- By eliminating the need to touch the surface, non-contact infrared pyrometers are less likely to be contaminated and thus produce more accurate measurements. Non-contact infrared pyrometers are ideal for measuring high-temperature materials as they do not transfer heat to the surface, which could skew the results.
- This type of pyrometers is less expensive and more reliable than contact sensors. In situations where the sensor must be installed at great distances from the target, non-contact sensors may be the only option.
- Non-contact infrared pyrometers are not damaged by contact with the measured item, so they can be used for in-process measurements or to monitor the condition of the equipment that cannot be shut down or moved for inspection. They can be used in danger from sparks or flames, such as in petrochemical facilities.
- Non-contact infrared sensors can be used in diverse environments such as high-temperature processes (up to 3200°C) or hazardous environments since there is no physical contact between sensor and object.
- Another advantage of non-contact sensors is their ability to continuously monitor the process or product condition from a remote location, which is impossible with contact sensors.
Summary – Accurate sensors have wide ranges of high temperature pyrometer available to meet different needs of the customers. It is very useful because it precisely measures the temperature at which an item is burning. The high accuracy of Accurate sensors makes them suitable for measuring temperatures at high temperatures in process plants and manufacturing facilities. They also feature a rugged design and long-term stability, which makes them ideal for use in demanding environments.
