  • Page 8: Introduction

    The Platinum Resistance Thermometer (PRT) model 5616 is designed to be a secondary standard interpolating instrument converting temperature to resis- tance. The 5616 may also be used as a temperature standard for calibration of industrial sensors. The PRT is used with a readout device to detect temperature changes or actual temperature.

  • Page 10: Installation

    Installation Lead Wire Identification The 5616 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 read- out instrument. Be sure to follow the manufacturer’s instructions for the read- out instrument and the heat source. Immersion Requirements Stem effect can cause measurement errors for any thermometer.
  • Page 13 5616 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.
