When it comes to refrigeration, the subject is near and dear to our heart here at your refrigeration installation company in St Louis near O’Fallon MO. We like to report to our readers and consumers, all of the latest news out there in order to do three things. We wish to help you make better informed decision in the event you need commercial refrigeration service. We want you to know what to do the next time you are in the market for an additional or a replacement commercial refrigerator and finally, we hope to help keep you informed of anything interesting that the St Louis Commercial Refrigeration industry happens to uncover for the simple sake of being in the know.
For the above reasons, today, we talk about oil-filled temperature sensors. Being that they are one of three, general sensor options along with electronic or gas-filled, we may discuss all three over the next several posts, but today, we start with oil-filled and take a little of our information in the form of research done on a site known as nrminc.
In the commercial world, an oil-filled sensor becomes especially beneficial for those who need to track the internal temperature of a stored product. According to nrminc, “In refrigeration applications, most temperature sensors, of any design type, electronic or gas-filled, are intended to respond very quickly to changes in ambient air temperature. This allows for precise measurement and control of temperature fluctuations. However, in some cases it is desirable to measure temperatures with a slower-responding sensor.” This is exactly the case when wishing to track something like the internal temp of a stored product. This will likely change much more slowly than the air of the space around it. “This can be easily accomplished by putting an insulating material around the temperature-sensing bulb. That material could be rubber, or expanding foam, or anything that will provide additional thermal mass around the sensing element. But the industry standard for this type of sensor is to suspend the sensing element in an oil bath, typically in a cube-shaped enclosure somewhat smaller than a deck of playing cards.”
