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

Reduce risk on critical projects

On time

Following standardized 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.

On budget

Traditionally, sensor procurement for critical programs required that additional sensors for destructive qualification tests be purchased for each lot, increasing the total cost of 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 to sensor buyers at no additional cost. With HR sensors, you only pay for the sensors that you use.
