SECTION 15 j. RTD TEMPERATURE

MEASUREMENT CONT.

0.01 degrees C.

Supported Resolutions for Factory Programmed Probes:

XXX-RT1 Pt100 0.01 degrees C (385 & 392)

XXX-RT1 Ni 120 0.1 degrees C

XXX-RT1 Cu 10 0.1 degrees C

XXX-RT2 Pt1000 1.0 degrees C

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.
