 Configurable input for optional speed sensor.
 Simple Configuration and Monitor PC software included as well
as serial protocol information for digital interface to data
acquisition systems.
2 Features and Controls
The TT20K is a dynamic torque measurement system designed for
temporary installations. The TX20K Transmitter is mounted on the
rotating shaft along with a strain gage(s) and battery. The RX20K
Receiver is connected to the USB port of a PC. The TX20K and RX20K
communicate with one another using RF transceivers built into each.
The strain gage (torque) signal and status information is transmitted off
the shaft by the TX20K and received by the RX20K and then sent on to
the PC. Operational configuration information is sent from the PC,
though the RX20K to the TX20K on the shaft.
The TT20K system is compact yet powerful. Configuration and
monitoring is intuitive using the included PC software. Incorporation into
data acquisition systems can be accomplished using the serial digital
data available through the USB connection or the standard analog
output.
The RF transceivers in the TX20K and RX20K are user selected to
operate any of 16 different frequencies below. This allows up to 16
TT20K systems to simultaneously operate in fairly close proximity.
These RF frequencies are different than those of the TT10K system. So
TT20K and TT10K systems can also operate in close proximity without
interference.

The TX20K RF transmission power level is user adjustable. There are
four different levels that can be chosen depending on the specific
