Temperature Sensors
Industrial Standard Probe
The Industrial Standard Probes 1/5 DIN-R (straight), 1/5 DIN-A (angular) and 1/5 DIN-A-L (long angular) are built with selected raw materials, have high purity and are handled in a laboratory environment. Use differential bulb of high performance with mineral insulation and sheath, which gives them high vibration resistance and durability at an industrial level, with standard laboratory performing. Due to their high stability they can be used in the non-customized manner as 1/5 DIN standard or custom mode with ITS-90 or Callendar-Van Dusen coefficients, reaching very low uncertainties for long periods of time. In this situation, can be read on a accuracy compatible instrument, such as thermometers ST-501 and PT-511 models or used as reference probe for dry block calibrators.
Au-Pt Thermocouple
Presy Au/Pt thermocouple sensor follows the design, care selection of raw material and handling in accordance with NIST and McLaren guidelines. It is a high performance sensor, more robust and stable than PRT for high temperature and level of accuracy of secondary or primary temperature standards. R and S thermocouples use platinum alloys in their composition which causes deterioration in performance and variable behavior depending on ther immersionin the heat source (presence of non-homogeneities). The Au/Pt thermocouple developed by Presys uses Au and Pt wires with 99.999% of purity, and as these metals are very stable from 0 to 1000 °C, the stability of the thermocouple is excellent for this range. The international literature has extensively described the exceptional qualities of this type of thermocouple. Can be used with the Presy Precision Thermometer PT-511 which already has the Au/Pt thermocouple curve developed by Burns. The reading is obtained directly in temperature unit. This set calibrated by fixed points results in a digital thermometer with the best uncertainties for such a wide range as 0 to 1000 °C.
