Entries

• in Monitoring/Measurement/Thermometers/Thermostats

  Lakeshore manufactures and supplies two models of temperature monitors that operate down to 1.4 K, with the appropriate sensor. One model is a multi-channel temperature monitor that features eight sensor inputs. The other model is a single temperature monitor that supports diodes, and NTC and PTC resistors.

• in RTDs

  LakeShore provides positive temperature coefficient RTDs in platinum and rhodium-iron and negative temperature coefficients RTDs in germanium, Cernox HT, Cernox, carbon-glass and ruthenium oxide. Platinum RTDs are an industry standard with a temperature range of 14 K to 873 K for many precision metrology applications. Rhodium-iron sensors have a temperature range of 0.65 K to 500 K and ionizing radiation resistance. Cernox sensors have a temperature range of 0.10 K to 325 K and ionizing radiation resistance with low magnetoresistance, while Cernox HT has a temperature range of 0.10 K to 420 K. Germanium RTDs have temperature range of 0.05 K to 100 K and resistant to ionizing radiation. Carbon-Glass resistance cryogenic temperature sensors have a temperature range of 1.4 K to 325 K with  magnetoresistance less than Cernox. Ruthenium Oxide RTDs have a low magnetoresistance and follow a standard curve with a temperature range of 0.01 K to 40 K.

• in Thermocouples

  LakeShore offers thermocouples for a variety of cryogenic applications. Chromel-gold/iron thermocouples has a  relatively high thermoelectric sensitivity (>15 µV/K above 10 K). Type E (chromel-constantan) thermocouples is ideal for temperatures down to 40 K. Type K (chromel-alumel) thermocouples has a sensitivity of 4.1 mV/K at 20 K.
