Common Maintenance Issues & Tips - Temperature Sensors

Temperature sensors in cryogenic temperature ranges need to be rugged and insensitive to temperature. These temperature sensors are used in things such as cryo stages, cryo tanks, cryotherapy units, cryocoolers, and other extreme temperature controlled equipment.

There are a wide range of temperature sensors available for various temperature ranges. It is important to consider what is needed for your unit. You should always follow the advice of the manufacturer or contact Rutherford & Titan for further information.

The temperature sensors that are used in temperature controlled environments usually have a temperature range from -100 °C to +250 °C. Temperature sensors used for cryotherapy units are wide and varied. They all differ based on the manufacturer and unit itself . Some temperature sensors are analog while some temperature sensors are digital. 

Temperature sensors used in cryo units usually integrate with other systems such as vibration, pressure transducers and a temperature controller unit. Note that these items need to be changed out after a period of time, sometimes every six months or year depending on the unit itself.

It is recommended to have a spare temperature on site in case a temperature sensor needs to be replaced. Contact Rutherford & Titan to get a replacement or back-up temperature sensor for your cryotherapy machine. 

A temperature controller is used for temperature regulation; it can also include alarms on temperature changes and can turn off the cryo unit in the event that temperature fluctuations occur. Some units have this but not all, so you need to be cautious about which units have this feature built in. Otherwise you run the risk of personal injury, potentially even giving someone frostbite, as it will just cycle cold with no regulation or warning.

Likewise, some temperature sensors communicate with other items such as a temperature display or with your computer system, so temperature readings can be viewed and monitored while temperature fluctuations are in progress. Temperature sensors can also be incorporated into the temperature controller or temperature display units to regulate temperature changes.

At Rutherford & Titan, we are often asked, “When can we predict a failure?” Unfortunately, being able to predict failure is not always possible. Which is why Rutherford & Titan recommends having a spare temperature sensor on-site. It is a fairly easy swap if you have this part on-hand. You can opt to have one of our cryogenic specialists come out to make this exchange, or we can guide you through it remotely. If you need information on which temperature sensor you need for your specific cryotherapy machine, or if you need assistance with the change-out, give us a call today (855) 550-0508.
