Uncalibrated cryogenic temperature sensor
Specify the model number in the left column only, for example PT-103. |
| |
Calibrated cryogenic temperature sensor
Add the calibration range suffix code to the end of the model number, for example PT-103-14L. |

| ADD-LN* Matching PT Sensors to ±0.1 K at 77 K add $54 to each sensor. |
| *Must be purchased with all matching sensors, as well as with the sensor to be matched |
|
- Upper temperature of AL and AM packages is limited to 800 K.
- If your application requires more than one platinum resistor, up to five platinum resistors can be matched with one another to within ±0.1 K at liquid nitrogen temperature with the purchase of only one calibration. If absolute accuracy is required, one of these matched RTDs can be calibrated.
For larger quantities, or for different requirements, consult Lake Shore. At the time of order, add -LN to the model number.
Example: PT-102-14D-LN is a PT-102-LN RTD with a calibration range of 14 K to 100 K that is matched with at least one other uncalibrated PT-102 to within ±0.1 K at liquid nitrogen temperature.
- For metrological applications below 30 K, use a germanium RTD. PT-100 sensors are not useful below 14 K for metrology and are of limited use below 30 K for temperature control, due to rapid decline in sensitivity.
- For use above 500 K, anneal at Tmax +10 °C for 4 hours.
