Select the Right Cryogenic Temperature Sensor with this hand selection guide from our partners at Lake Shore Cryotronics.
Selecting the appropriate sensor requires an understanding of different sensor technologies. This Temperature Selection Guide lets you quickly identify the right sensor for your research application.
Each sensor technology is compared across six attributes:
- Temperature range
- Accuracy and resolution
- Magnetic resilience
- Radiation resilience
- Package options
- Price
Each sensor has been given a rating for six attributes or characteristics. These ratings give a
general idea of how a sensor will perform and aid in the early decision making process,
but are not a substitute for detailed specifications. Click the link below below for more information about eachf the six attributes and how they will help you decide which sensor is for you.

TEMPERATURE RANGE
It is important to select sensors that suit the temperature range of the intended system. The low-end temperature rating generally indicates where the sensor type starts to perform poorly, whereas the upper
rating is the point where the sensor will begin to sustain permanent damage.
ACCURACY AND RESOLUTION
The Accuracy and Resolution rating for each sensor type takes into account the amount of uncertainty in the measurement by the sensor with respect to an absolute standard, as well as sensitivity over the temperature range of interest.
MAGNETIC RESILIENCE
The Magnetic Resilience rating for each sensor type is a comparative rating of the sensor’s accuracy in magnetic field. The higher the rating, the less the sensor shifts when exposed to magnetic field.
RADIATION RESILIENCE
The Radiation Resilience rating is a measure of a sensor’s ability to withstand exposure to ionisng radiation. Sensors with a high rating will have a greater ability to stay within calibration after exposure.
High energy physics experiments and space applications often need to consider this
variable.
PACKAGE OPTIONS
Good thermal contact is vital when making cryogenic temperature measurements. Having a wide range of
packaging options will make it easier to find a solution that is optimal for a given system.
PRICE
Each sensor type has been given a rating for price. This rating takes into account the total price of the sensor type without the addition of package options, and should only be used as a tool to compare Lake Shore sensors.
