What are temperature calibrators used for?

“What are temperature calibrators used for?” This is an important question that is asked by many people. Here we will answer the question to allow you to make the right choice when selecting a temperature calibrator for yourself.

Imagine that you making an important product where the temperature is imperative to be maintained within a very small window, if it is exceeded or not reached then the product will be spoiled.

You have a very good PID process temperature controller that is able to maintain the required temperature window. You also have a good PT100/RTD or thermocouple sensor that is able to measure the process temperature.

You then start to measure the process and all seems to be working well for several weeks. Then one day you find that a batch process has been rejected and then the following day it happened again. You check the process controller readings and this is reading correctly. The temperature sensor also hasn’t moved out of position. You then start to scratch your head what has changed to cause these batch rejections?

The answer is temperature sensor drift. This is caused by the temperature sensor getting contaminated by external forces such as foreign objects/liquids, vibration or extreme temperatures.

This all could cause a product line to shut down which is a costly way to establish that the temperature sensor and temperature controller needs calibrating or replacing.

It is therefore important to put in place a strict preventative calibration program.

The use of one of our temperature calibrators will ensure that your process control is kept within the set parameter.

We have two types ideal for consideration, one is a Wet/Dry calibrator and the other is a Dry block calibrator.

Both are suitable for carrying out the mission. To find out more about the two different types, click here.
