6 TYPES OF THERMOMETERS THAT NEED TO BE CALIBRATED

Did you know that temperature sensor or thermometer also needs to be calibrated regularly. By calibrating regularly, your company can ensure that the temperature sensor used provides accurate measurement result. At the end an accurate result shall improve product quality, operational safety and overall process efficiency.

In this article, we will elaborate what kind of temperature sensors that are crucial to be calibrated regularly.

1. Digital Thermometer

A digital thermometer is a temperature measuring uses an electronic sensor to measure temperature and displays the result in digital form. Although a digital thermometer tends to be more stable and accurate than the analog, this tool still require regular calibration. It is to ensure that its reading match the actual temperature.

2. Infrared Thermometer

An infrared thermometer is a non-contact temperature measuring sensor that uses infrared rays to measure the surface temperature of objects. It is very useful for measuring the temperature of hard-to-reach objects or in situations where contact with the object is undesirable.

3. Bimetal Thermometer

A bimetallic thermometer is an analog temperature sensor that uses two different metals wound together to measure temperature. When the temperature changes, the difference in expansion between the two metals causes bending that can be shown on the thermometer scale. Although this tool is simple, a bimetal temperature sensor also needs to be calibrated regularly.

4. Thermocouple

A thermocouple is a temperature sensor consisting of two wires of different metals connected at one end and measured at the other end. Changes in temperature cause changes in electrical voltage, which can be converted into temperature readings. Some common applications that use a thermocouple include HVAC (Heating, Ventilation, and Air Conditioning), industrial processes (chemical plants, petroleum refining, metalworking, and food processing), power generation, automotive, medical, etc.

5. Thermistor

A thermistor is a temperature sensor that changes its resistance linearly with changes in temperature. There are two types of thermistors: positive type thermistor (PTC) whose resistance increases with increasing temperature, and negative type thermistor (NTC) whose resistance decreases with increasing temperature.
Some applications that use thermistor include motor vehicles, household appliances, and HVAC (Heating, Ventilation, and Air Conditioning) systems.

6. Liquid Thermometer

A liquid thermometer uses a column of liquid, such as mercury or alcohol, to measure temperature. A change in temperature causes a change in the volume of the liquid, which is indicated on the thermometer scale. A liquid thermometer still used in some locations and situations even though there is a concern in health and safety associated with the use of mercury,
