Introduction
This chapter describes the basic features of the PowerDAQ™
Thermocouple Rack (TCR).
About the PowerDAQ™ TCR
Thank you for purchasing a PowerDAQ™ TCR. The PowerDAQ™
TCR board was designed to work with your PowerDAQ OCI data
acquisition board.
The PowerDAQ Thermocouple Rack contains sixteen isolated
inputs for J or K type thermocouples. It converts the thermocouple
inputs to a voltage, and then it is fed as an input to a PowerDAQ
PCI board, with an input range of 0-10V.
The PD-TCR is based on a complete instrumentation amplifier and
includes a thermocouple cold junction compensator for each
channel. It combines an ice point reference with a precalibrated
amplifier to produce a high level (10 mV/C) output directly from a
thermocouple signal.
Each PD-TCR channel is precalibrated by laser wafer trimming to
match the characteristic of type J or K inputs.
Chapter 1: Introduction
The temperature transducer voltages (ZERO potentiometer) and
gain control (GAIN potentiometer) can be used to recalibrate the
PD-TCR in the field.
The PD-TCR channel accuracy for both the J and K type is ±1% is
a working temperature environment of 0°C to +50°C.
Features
The major features of the PowerDAQ™ TCR are:
• Each channel provides cold junction compensation
• Zero, and scale factor are all pre-calibrated by laser wafer
trimming
• Calibrate ZERO and gain for each channel
• Differential input rejects common-mode noise voltage on the
thermocouple leads
• Includes PowerDAQ SDK
PowerDAQ PCI Board User Manual 2

Chapter 1: Introduction
• Data logging and display software with source code in Delphi
• LabVIEW for Windows VI's

channel boards
• Up to 64 Non multiplexed inputs per system
• Uses PowerDAQ PCI bus DAQ boards
• Multiple PowerDAQ boards can be plugged into one PC. Only
limited by PCI slots

Installation and Configuration
This chapter describes the hardware and software installation and
configuration of the PowerDAQ™ TCR.
Unpacking
Your PowerDAQ™ TCR is wrapped in an antistatic bag to protect
against electrostatic charges that might damage the board. To avoid
damage, proceed as follows:
1. Ground yourself with a grounded wrist strap or grounded
source.
2. Discharge the static electricity by taking the board in the
antistatic bag and touching the metal part of your PC.
3. Remove the board from the antistatic bag. We suggest you
save the bag.
4. Inspect the board for any damage. If any damage is found,
notify your distributor to return the board to the manufacturer.
See Appendix B: Common Questions and Support.
Note
The PowerDAQ™ TCR contain sensitive electronic
components. Please make sure the proper grounding and
electrostatic conditions are used.
Hardware
You can install your PowerDAQ™ TCR as a stand-alone unit or in
a 19" rack. We recommend you use the following instructions:
1. Turn the PC Off.
2. Refer to your PowerDAQ PCI board hardware manual for
DAQ board installation instructions.
3. The PD-TCR requires external power to be wired at the J3
EXT POWER connector. (The manufacturer suggests using
the PD-PSU-5/15 power supply unit. This PSU is switchable
110/220V and can support up to 4 PD-TCR's).

precision, you should recalibrate the board in the actual working
environment.
Note
Allow the host PC and the board to warm up for at least
one hour before calibration.
Equipment required

Questions and Support
Q
THERMOCOUPLE BASICS
A
Thermocouples are economical and rugged; they have reason-ably
good long-term stability. Because of their small size, they respond
quickly and are good choices where fast response is important.
They function over temperature ranges from cryogenics to jet-engine
exhaust and have reasonable linearity and accuracy.
Because the number of free electrons in a piece of metal depends on both
temperature and composition of the metal, two pieces of dissimilar metal
in isothermal and contact will exhibit a potential difference that is a
repeatable function of temperature. The resulting voltage depends on
the temperatures, T1 (unknown temperature) and T2 (ice point reference)
, in a repeatable way.
Since the thermocouple is basically a differential rather than absolute
measuring device, a known reference temperature is required for one of
the junctions if the temperature of the other is to be inferred from the
output voltage. Thermocouples made of specially selected materials have
been exhaustively characterized in terms of voltage versus temperature
compared to primary temperature standards. Most notably the water-ice
point of 0°C is used for tables of standard thermocouple performance.
An alternative measurement technique, is used in most practical
applications where accuracy requirements do not warrant maintenance
of primary standards. The reference junction temperature is allowed to
change with the environment of the measurement system, but it is
carefully measured by some type of absolute thermometer. A
measurement of the thermocouple voltage combined with a knowledge of
PowerDAQ PCI Board User Manual 26
Page 34
B
B
the reference temperature can be used to calculate the measurement
junction temperature. Usual practice, however, is to use a convenient
thermoelectric method to measure the reference temperature and to
arrange its output voltage so that it corresponds to a thermocouple
referred to 0°C. This voltage is simply added to the thermocouple voltage
and the sum then corresponds to the standard voltage tabulated for an
ice-point referenced thermocouple.
The temperature sensitivity of silicon integrated circuit transistors is
quite predictable and repeatable. This sensitivity is exploited in the PDTCR to produce a temperature related voltage to compensate the
reference of “cold” junction of a thermocouple.
----------------------------------------------------------------------------------------
Q
USING TYPE T THERMOCOUPLES WITH THE PD-TCR
A
Because of the similarity of thermal EMFs in the 0°C to +50°C
range between type K and type T thermocouples, the PD-TCR can be
directly used with both types of inputs. Within this temperature range the
°
PD-TCR should exhibit no more than an additional 0.2
calibration error when used with type T inputs. The error arises because
the ice point is trimmed to type K characteristics at 25
----------------------------------------------------------------------------------------
Q
ALARM CIRCUIT (OPEN THERMOCOUPLES)
A
The PD-TCR software will detect open thermocouple channels. This
occurs when the value read by the software is random.
----------------------------------------------------------------------------------------

C output
°

Page 35
B
B
Q
THERMAL ENVIRONMENT EFFECTS
A
The inherent low power dissipation of the PD-TCR and the low
thermal resistance of the channel make self-heating errors almost
negligible. For example, in still air the channel to ambient thermal
resistance is about 80C/watt. At the nominal dissipation of 800 W the
self-heating in free air is less than.065C. Submerged in fluorinert
liquid (unstirred) the thermal resistance is about 40C/watt, resulting in
a self-+T heating error of about 0.032C.
----------------------------------------------------------------------------------------
Q
STABILITY OVER TEMPERATURE
A
Each PD-TCR is tested for error over temperature with the
measuring thermocouple at 0C. The combined effects of cold junction
compensation error, amplifier offset drift and gain determine the stability
of the PD-TCR output over the rated ambient temperature range.
