The OMEGA® MWTC Wireless Smart Thermocouple
Connector Series features stand-alone, compact,
battery powered thermocouple connectors that transmit
measurement data back to a mating receiver up to 90 m
(300') away. When activated the connector will transmit
readings continuously at pre-set time interval that was
programmed by the user during the initial setup.

Each unit measures and transmits: thermocouple
input reading and connector ambient temperature to
a receiver and is displayed on the PC screen in real
time using the free provided software. When used
with an MWTC-REC receiver, data from multiple
wireless thermocouple connectors can be received
and displayed. Each unit includes free software that
converts your PC into a strip chart recorder or data
logger so readings can be saved and later printed or
exported to a spreadsheet file.

The MWTC can transmit thermocouple
readings wirelessly to your PC, up to
300' away.

The MWTC-REC series is a family
of wireless receivers designed to
work with the MWTC transmitters.
Three models are available to meet
your application needs, with either
USB communication to a PC, or
analog output(s) to drive a remote
display, recorder, data logger or
PLC. Transmissions of up to 90 m
(300') are possible with the MWTC.

The MWTC-REC1 is a compact
multi-channel receiver that connects
to your PC through a 1.8 m (6')
cable (included). It is capable of
working with up to 48 individual
MWTC wireless connectors.
The miniature MWTC-REC5 is
designed for shorter distances,
such as testing and laboratory
applications. The size of a flash
drive, the MWTC-REC5 plugs right
into USB port. The MWTC-REC6 is
a compact, single channel receiver
that provides an analog output that
corresponds to the input range of
the MWTC wireless connector it is
paired to.
