K-type Thermocouple
Model: ATB1
Max: 400ºF
(204°C)
OPERATOR’S MANUAL
Description
The ATB1, K-Type, thermocouple can be used
continuously to take temperature readings up to
400ºF (204°C) and a one time use of 482ºF
(250°C). The ATB1 can be used with any ther-
mometer which accepts a K-type thermocouple.
The velcro allows the user to strap the ATB1 to a
pipe, allowing the user to take hands free, more
accurate measurement. The ATB1 also comes with
a wrap tab making it easy to wind and store the
thermocouple.
Operation
To use the ATB1 plug it into any ther-
mometer accepting a K-type thermo-
couple and adjust the device to the
appropriate settings. To use velcro
strap, insert the thermocouple through
the velcro as shown to the right and
strap it so the pipe is in contact with the
thermocouple bead.
Calibration
Due to variances in the thermocouple wire and
other parts of the system, a field calibration should
be conducted before use. Field calibration typically
gives ±1º overall accuracy. The instructions for this
calibration should be in the operating manual for the
thermometer.
Broken Wires:
Due to frequent bending, the K-type thermocou-
ple wire may break or come loose, typically near the
plug. To repair, cut and strip the thermocouple wire
near the plug. The red wire is the (-) wire and it
belongs on the wider of the two plugs. Loosen the
screws on plugs and wind the conductors around
the appropriate screws and tighten. Finally, position
the plugs into the tab and screw the tab back togeth-
er.
Specifications
Thermocouple Conductors: K-type Nickel
Chromium/Nickel Aluminum, 2300ºF (1260°C)
maximum (insulation limits max. see probe insu-
lation).
Accuracy:±4ºF @ -50 to 400ºF; ±2°C @ -46 to
204°C
Range: -50 to 400ºF; -46 to 204°C maximum con-
tinuos operation. Single exposure use at 482°F
(250°C).
Probe insulation: While calibration and atmos-
phere will affect maximum useful temperature in
applications, this insulation is designated to
withstand a maximum continuous use at 400°F
(240°C) and a single exposure use at 482°F
(250°C).
Plug: K-Type Thermocouple male mini plug.
