The Platinum Resistance Thermometer (PRT) models 5627A is designed to be a secondary standard interpolating instrument converting temperature to resis- tance. The 5627A may also be used as a temperature standard for calibration of industrial sensors. The PRT is used with a readout device to detect tempera- ture changes or actual temperature. -

Page 8: Installation
Installation Lead Wire Identification The 5627A PRT is equipped with a four-wire cable (see Figure 1). Four lead wires are used to cancel lead wire resistance. For best results, the readout de- vice should be equipped to handle four-terminal resistors. -

5 PRT Care and Handling Guidelines PRT Care PRT Care and Handling Guidelines PRT Care CAUTION: READ THIS SECTION BEFORE REMOVING THE PRT FROM THE SHIPPING BOX OR CASE Care must be taken in handling the PRT to maintain calibration accuracy. Care should still be used when handling the PRT even though the Inconel sheath is durable and provides good protection for the sensor. -

6 Operation General Operation General For best results, be familiar with the operation of the heat source and the readout instrument. Be sure to follow the manufacturer’s instructions for the readout instrument and the heat source. Immersion Requirements Stem effect can cause measurement errors for any thermometer. This error is due to heat lost or gained by the sensing element through the thermometer stem. - Page 11 5627A PRT User’s Guide temperature increases, even if the seal is not broken. When the insulation resis- tance becomes sufficiently low, performance suffers. A good rule of thumb is that the transition junction is too hot when it is hot enough to burn your thumb.
