The HHC can be used with several standard Thermocouple types
for precision temperature measurements. The Thermocouple
Interface Module XXX-TC1 allows the HHC base unit to read the
input of a thermocouple measuring device. The XXX-TC-1 ther-
mocouple modules support the following thermocouple types:
TYPE
Material
J
Iron & Copper (Constantan)
K
Nickel-Chromium & Nickel-Aluminum
T
Copper & Copper-Nickel (Constantan)
E
Nickel-Chromium & Copper-Nickel (Constantan)
R
Platimun-13% Rhodium & Platinum
S
Platimun-10% Rhodium & Platinum
B
Platimun-30% Rhodium & Platinum-6% Rhodium
N
Nickel-Chromium-Silicon & Nickel-Silicon-Magnesium
Several parameters associated with Thermocouple temperature
measurement can be selected including:
• Engineering units or direct millivolt readout for any type of ther-
mocouple
• Choice of internal or external reference junction
• Selectable resolution or automatic resolution (selects maximum
possible )
1. Attach the thermocouple to a male miniature thermocouple
connector (Omega type SMPW) to the module. Install the
thermocouple into the interface module by inserting the metal
blades of the miniature connector into the slots in the receptacle
located on the thermocouple interface module.
Note: Connectors are specifically manufactured for each ther-
mocouple type and will be marked accordingly. Failure to use the
properly mated connector will result in additional inaccuracy.
2. Install the thermocouple interface module into either of the two
HHC module bays.
