5606, 5607 Full Immersion PRT
General
2 Introduction
2.1 General
The Hart Platinum Resistance Thermometers (PRT) models 5606 and 5607, are designed to be a precision instrument converting temperature to resistance. The PRTs are
used with a readout device to detect temperature changes or actual temperature.
2.2 Application
The 5606 and 5607 Full Immersion PRTs are designed to perform in extreme environments where both the transition junction and the lead wires are required to withstand
temperatures covering the entire operating range of the probe.
The 5606 Immersion PRT has been designed to be fully immersed in common heat
transfer uids such as silicone oil, mineral oil, ethanol, and liquid nitrogen and can
measure temperature ranging from –200 °C to 160 °C.
The 5607 Immersion PRT is intended to be used in dry mediums only but can be fully
immersed in ovens, furnaces, or autoclaves over a temperature range of 0 °C to 450 °C
2.3 Calibration
In order for any instrument to be used as a standard it must be calibrated. These
instruments are sold uncalibrated unless calibration is requested at time of purchase.
They are satisfactory as secondary standards and may be calibrated by comparison to
primary standards.
2.4 Recalibration
The recalibration of the 5606/5607 Full Immersion PRT should be scheduled according to the user’s company Quality Assurance requirements. Normally, a PRT is recalibrated annually. Unless the PRT is used only over a limited range, calibration over
the full range of the PRT is recommended. For information on calibration services for
the 5606/5607, contact an Authorized Service Center for an RMA number and current
pricing (see Section 1.3, Authorized Service Centers, on page 2)
Depending on the user’s Quality Assurance requirements, the PRT drift should be
checked periodically at the Triple Point of Water (TPW) or 0 °C. Section 8.1, Troubleshooting, on page 11, provides information on drift with respect to mechanical shock
and oxidation. If the R
ances, a full recalibration should be scheduled.

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 prole,
the 5606 PRT was designed without a traditional transition junction and strain relief.
Extra care should be taken when handling the lead wires of the 5606.
The lead wire of the 5607 is shielded with braided stainless steel and connected to the
transition junction with a strain relief spring. The transition junction and lead wire of
the 5607 PRT have been designed to withstand temperatures from 0 °C to 450 °C but
should be immersed in dry mediums only. The transition junction and lead wires of
the 5607 PRT should not be directly immersed in uids of any kind. If a measurement
must be made in a uid medium, the transition junction and lead wires of the 5607
can be shielded from exposure to uids by inserting the entire probe assembly into a
sufciently long, close-ended stainless steel or glass tube. Additional stabilization time
should be considered to allow for complete temperature equilibration.

4.1 Environmental Issues
Ideally, temperature calibration equipment should be used in a calibration laboratory
or other facility specically designed for this purpose. Environmental requirements
include:
Stable temperature and relative humidity <80%
Clean, draft-free area
Low noise level: low radio frequency, magnetic or electrical interference
Low vibration levels
4.2 Mounting
When in use, the PRT must be mounted carefully to avoid any damage to the sheath
or sensor. If using mechanical clamps to secure the PRTs while in use, care should
be taken not to over tighten the clamping device. Over tightening will damage the
sheath or lead wires. If metal comparison blocks are used in the bath, maintain a
close t between the thermometer sheath and the well in the comparison block. However, allow for the thermal expansion of the thermometer sheath when determining
block well tolerances.
Installation
4.3 Lead Wire Identication
The 5606 and 5607 PRTs are equipped with a four-wire cable. The same circuit schematic 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.
Figure 1
PRT Schematic
The lead wires are four different colors. Lead wire pairs attached to each end of the
sensor are identied as shown in Figure 1 on this page.

PRT Care
5 PRT Care and Handling Guidelines
5.1 PRT Care
CAUTION: READ THIS SECTION BEFORE REMOVING THE PRT
FROM THE SHIPPING BOX OR CASE
The 5606 and 5607 Platinum Resistance Thermometers (PRTs) are delicate instruments. 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.
However, care should still be used when handling the PRT even though the metal
sheath is durable and provides good protection for the sensor. Correct handling of the
PRT will prolong the life expectancy. When not in use, the PRT should be stored in a
safe place where the risk of unintentional mechanical shock is minimized.
NOTE: The PRT sheath changes color after use at high temperatures. The PRT
may arrive with a brown tint to the sheath due to calibration at high
temperatures.
5.2 PRT Handling Guidelines
DO measure the R
DO keep the thermometer as clean as possible.
DO immerse the thermometer in the appropriate liquid for the temperature
range. If a dry block is used, the well diameter should allow the PRT to
comfortably slip in and out without excess movement. For best results, immerse
the thermometer as deep as possible to avoid “stem effect” (the temperature
error caused by the conduction of heat away from the sensor).
DO allow sufcient time for the thermometer to stabilize before making
measurements. This allows for the best accuracy.
DO use the correct drive current with the thermometer to prevent error in
temperature or resistance. Hart Scientic recommends 1mA.
DO use the protective shipping box or case provided or other protection when
the thermometer is not in use.
DO NOT subject the thermometer to any physical shock or vibration.
DO NOT use pliers or other devices to squeeze the sheath. This action can
permanently damage the PRT.
DO NOT subject the thermometer to temperatures above the highest specied
operating temperature.
DO NOT screw a clamp down so tight that it dents the sheath. This can
permanently damage the PRT.
DO NOT expose the 5607 transition junction and lead wires to liquid.

6 Operation
6.1 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.
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. However, to follow
“good” practice procedures, always measure the triple point of water (Rtp) after each
temperature measurement. The following equation provides the most accurate measurement of the ratio:
R
W
All PRTs experience errors caused by self-heating of the element. Self-heating is a
combination of two factors, heat dissipation and heat sink. Self-heating error can be
reduced to have a negligible effect if the PRT is used with the same excitation current
and medium in which it was calibrated.

Operation
Thermal EMF
6.3 Thermal EMF
Two factors contribute to thermal EMF, chemical consistency and physical consistency. Variations in chemical structure due to impurities can contribute to thermal EMF.
Also discrepancies in crystal structure can contribute to thermal EMF. These factors
are minimized by annealing the full length of wire before construction of the PRT.
Likewise, connection to extension lead wires and readout instruments can be a source
of thermal EMF. The thermal EMF is caused by a difference in temperature between
two connections. If the two connections are the same temperature, there will be little
or no thermal EMF effects. However, if there is a substantial temperature difference
between connections, the thermal EMF effects will be signicant. Therefore, cover or
insulate any exposed bridge or galvanometer terminals to lessen the source of error.
The effects of thermal EMF can be canceled by using an AC bridge or a DC bridge
with reversible current.

8.1 Troubleshooting
In the event that the probe appears to function abnormally, this section may be of use
in solving the problem. Several possible problem conditions are described along with
likely causes and solutions. If a problem arises, please read this section carefully and
attempt to understand and solve the problem. If the probe seems faulty or the problem
cannot otherwise be solved, contact an Authorized Service Center (see Section 1.3,
Authorized Service Centers, on page 2) for assistance. Be sure to have the model number and serial number of your probe available.
Problem Causes and Solutions
Data changes greater than 0.1°C
are observed
Data unstable If the data is unstable at the Triple Point of Water (TPW), check
Temperature readout different
than expected, e.g. the heat
source is set at 300°C, the PRT
measures 275°C.
Mechanical shock can cause temperature errors as great as 0.5°C.
If this is observed, recalibrate the PRT.
the connector. If the connector is correct, contact an Authorized
Service Center (see Section 1.3, Authorized Service Centers, on
page 2). The PRT may be damaged and need repair.
If the data is unstable at high temperatures, it may be due to
electrical noise in the system. Reduce the temperature and
observe the data. If it is stable, electrical noise is interfering with
the measurements at high temperatures. Check the grounding of
the readout device and the heat source. A faulty ground on either
device could interfere with high temperature measurements. A
ground wire attached to the metal sheath of the PRT may help to
reduce electrical noise interference.
Measure the PRT resistance at TPW.
If the resistance of the PRT is less than the rated resistance, e.g.
70W for the 5606/5607, there may be a short in the sensor. Contact
an Authorized Service Center (see Section 1.3, Authorized Service
Centers, on page 2).
If the resistance of the PRT is only a few ohms, there may be a
short in the four lead-wires. Contact an Authorized Service Center
(see Section 1.3, Authorized Service Centers, on page 2).
If the PRT is open, the resistance will be “Out of Limits” or in the
kilohm or megohm range. Contact an Authorized Service Center
(see Section 1.3, Authorized Service Centers, on page 2).
