2.2 Application The 5606 and 5607 Full Immersion PRTs are designed to perform in extreme environ- ments where both the transition junction and the lead wires are required to withstand temperatures covering the entire operating range of the probe.

–4 3.2 Lead Wire and Transition Junction The lead wire of the 5606 Full Immersion PRT is made of single-conductor enameled copper wire which prevents moisture from wicking to the sensing element as it would if a more common,stranded lead wire were used. In order to maintain its small profile, the 5606 PRT was designed without a traditional transition junction and strain relief.
4.3 Lead Wire Identification The 5606 and 5607 PRTs are equipped with a four-wire cable. The same circuit sche- matic applies to both PRTs (see Figure 1 on this page). Four lead wires are used to cancel lead wire resistance. For best results, the readout device should be equipped to handle four-terminal resistors.
CAUTION: READ THIS SECTION BEFORE REMOVING THE PRT FROM THE SHIPPING BOX OR CASE The 5606 and 5607 Platinum Resistance Thermometers (PRTs) are delicate instru- ments. Care must be taken in handling the PRTs to maintain calibration accuracy. The partial stress free design of the PRT sensor reduces the effects of mechanical shock.
Operation ThermalEMF 6 Operation 6.1 General For best results, be familiar with the operation of the heat source and the readout in- strument. Be sure to follow the manufacturer’s instructions for the readout instrument and the heat source. 6.2 Comparison Calibration of Other Instruments The uniformity and stability of the heat source and the degree of accuracy required determine the number of temperature measurements necessary.
CaseOptions 7 Accessories 7.1 Case Options The 5606/5607 PRT comes in a rigid case, Hart model 2601, appropriate for the length of the probe. 7.2 PRT Termination The PRT can be terminated in four ways (Figure 2 on this page) depending on the user’s requirements:...
If the resistance of the PRT is less than the rated resistance, e.g. source is set at 300°C, the PRT 70W for the 5606/5607, there may be a short in the sensor. Contact measures 275°C. an Authorized Service Center (see Section 1.3, Authorized Service Centers, on page 2).
