Reference Standard Sensors

SSPRT provides an affordable alternative for precision temperature measurement and calibration in labs & fields. Metal Sheathed Semi Standard Platinum Resistance Thermometer is widely used as a reference to calibrate various temperature probes, particularly in secondary calibration laboratories. SSPRT is constructed with a 6 mm outer diameter metal sheath of high durability. Inside the sheath, the sensing element is protected to shield the sensor from contamination by free-floating metal ions found within the metal environment at high temperatures. The electrical configuration is a four-wire current potential hookup to eliminate the effect of lead wire resistance. A special powder mixture is filled into the sensor capsule to support the element wire to protect the element from mechanical shocks. The element is housed in a special protective Assembly to ensure minimum drift over long term use.

High accuracy Platinum Resistance Thermometer (PRT) is an interpolating instrument converting temperature to resistance. It works together with readout device to measure temperature or change of temperature. It has wide applications for dry-wells or temperature baths.

It is recommended to calibrate this PRT annually over the full temperature range in between annual calibrations; user can check the drift rate by comparing RTPW against the last Calibration results.

Accuracy

• ±0.31°C at -80°C
• ±0.15°C at 0°C
• ±0.35°C at 100°C
• ±0.65°C at 250°C
• ±0.95°C at 400°C

K type secondary thermocouples are used as master thermocouples in comparison method of temperature calibration using dry block temperature calibrators. They have special class accuracy i.e. 1.1°C or 0.4% of temperature whichever is greater.

Tempsens offers special Reference thermocouples for high temperatures up to 1500°C for highly accurate temperature measurement. These Thermocouples are offered in platinum / Rhodium (type R, S or B) elements with a high purity Alumina insulations and sheath materials.

Thermocouples employing platinum in combination with platinum-rhodium alloys have been found to be the most reproducible of all the various types. They are resistant to oxidation in air and, because of their high melting points, can be used at very high temperatures. The best-known member of this group is the Type S (Pt10Rh/Pt) or Type R (Pt13Rh/Pt).

It was long considered more accurate and has probably been studied more than any other thermocouple. The performance of Type R or Type S thermocouples depends strongly on the annealing process, materials used and other construction techniques.

Key Features:

• High purity Alumina insulation and sheath materials


• Accuracy Special class of 0.6 °C or 0.1 % of temperature whichever is greater
