HR Series Sensors

High reliability sensors

The HR Series is a new line of high reliability cryogenic temperature sensors for mission-critical applications. Starting with our proven temperature sensor technology, we have developed a family of off-the-shelf sensors that have already undergone extreme testing steps 
to assure you of extra reliability.

For when the best needs to be better

In situations where cryogenic temperature control or monitoring forms a critical component of a system and the cost of sensor failure far exceeds the cost of the sensor, subjecting sensors to a higher level of scrutiny becomes vital. Projects where outcomes are worth far more than the sum of their parts are prime examples of this and include:

  • Space telescopes
  • Supercolliders
  • Fusion reactors
  • Research satellites
  • Maglev locomotives

Get your project to completion on time, under budget

Save time
Following standardised testing procedures, these sensors are built on regular production schedules and stocked for rapid delivery, resulting in lead times comparable to standard commercial sensors. Predefined testing protocol also cuts paperwork—no need to define different detailed sensor requirements for every program.

Save money
Traditionally, sensor procurement for critical programs required that additional sensors for destructive qualification tests be purchased for each lot, increasing the total cost to the project without increasing the number of sensors that are available to install. HR sensors are different. Lake Shore performs the qualification testing for each lot, with the resulting screening and qualification test report being supplied at no additional cost to sensor buyers. With HR sensors, you only pay for the sensors that you use.

Reduce risk
In some scenarios, sensors are required to fall within specific resistance ranges or exhibit certain sensitivities at different temperatures. Lake Shore HR Series sensors reduce the risk to a project’s timeline by allowing customers to see resistance and sensitivity data on all stocked HR sensors. This information can be useful for pre-selecting and reserving sensors ahead of when they are actually required.
