Data Sheet

AQS-TC1 Thermocouple Temperature Modules

FEATURES

Allows ST-2A to measure temperature with

a thermocouple

Pre-programmed to accept 8 most common

thermocouple types

Displays measurement for Farenheit, Celsius, Kelvin

Rankine and millivolts

Reference junctions: automatic internal or manual

external

PRODUCT SPECIFICATIONS:

THERMOCOUPLE TEMPERATURE MODULE Part Number AQS-TC

Unit of Measure (selectable):

°C, °F, °K, °R and millivolts

Reference Junction (selectable):

Automatic Mode: The AQS-TC1 module incorporates an internal resistor/

thermistor based reference junction, which may be selected for use in the

temperature readout mode.

Manual Mode:

An external reference junction may be used in place of the internal junction.

External reference junctions may be applied in the temperature or direct

millivolt readout modes.

Resolution Reading in Temperature Units (selectable):

1, .1 or .01 degrees. “Auto” mode selection that allows the ST-2A to

automatically configure the readout to the highest significant resolution

(resolution closest to the tolerance) for the thermocouple type selected.

Resolution Reading in Millivolts:

.001 millivolts

Thermocouple Connection (to interface module):

Requires a “miniature thermocouple connector” (Omega type SMP),

specifically matched to the thermocouple type to be used. These connectors

may be purchased as an accessory under the following part numbers:

(see how to order thermocouple connector table)

SYSTEM ACCURACY (READING IN TEMPERATURE UNITS):

Includes the base unit and AQS-TC1 interface module. (Does not include

inaccuracy of the thermocouple device. Consult thermocouple manufacturer

or ANSI MC96.1 for thermocouple accuracy specifications. Typical

inaccuracies range from ±1 to ±2. °C.)

Conversion Factors to convert °C specifications to other units of measure:

To convert from C to F; F = (1.8 x C) + 32

To convert from C to K: K = C + 273.15

To convert from C to R; R = (1.8 x C) + 427.6
