OMEGA’s TX20B radio telemetry
system is ideal for transmitting
signals from sensors that are
mounted on rotating shafts. The
TX20B Series miniature transmitters
modulate sensor signals from
thermocouples, voltage transducers,
or strain gage bridge circuits onto
an RF carrier and transmit them to
a stationary receiver. The RX20B
receiver demodulates the signals
and converts them into ±2V analog
output. Two analog output signals
are available simultaneously.
A wideband output provides
frequency response from DC to
1250 Hz. For maximum stability
of the signal, a filtered output is
also available with a 0 to 10 Hz
bandwidth.
TX20B transmitters incorporate
a crystal oscillator that is tuned to
a specific frequency, eliminating the

need for tuning by the operator.
Transmitter frequencies can be
staggered, allowing multiple
transmitters to operate in proximity
with no interference. Multichannel
receivers are available.
Transmitters are small enough to
be taped or strapped to the rotating
shaft, and they can be powered by
a 9V battery. For applications in
which continuous uninterrupted
monitoring is necessary, an
inductively coupled power supply
and transmitter are also available.
The TX20B operates in a band that
does not require an FCC license.
