Loop-Mates are novel
single-function low-cost pocket-sized units, designed for test
and calibration of process loops.
Simplicity of operation is their key, with no
keypads or complicated menu selections. Engineers will be able
to pick them up and get to work immediately. Just select 4-20mA
or 10V loop, and TxSim, RxTest, RxSim or TxTest.
The Loop-Mate1 is the simulator and acts as a
source to provide loop signals of 4-20mA or 0 - 10V.
No complicated selection of the output, just operate
up/down buttons to increase or decrease the signal. There are
seven set points: 0, 10, 25, 50, 75, 90 and 100%, each is indicated
on a high brightness LED and an audible beep sounds on each
change of output.
Auto-stepping mode (adjustable rate) allows Loop-Mate1
to be left connected automatically stepping up and down the
set points. This allows the engineer to move to another location
to check (using Loop-Mate2) that the signal is arriving correctly
and is within specification.
Loop-Mate2 is a dedicated loop signal indicator,
and is just as easy to operate.
Once again the user selects the loop type, 4-20mA
or 0-10V, and chooses whether the display is in direct units,
or percentage of span. The LCD shows the signal to an accuracy
of 0.05% either in milliamps, volts or percentage of span.
Both devices have internal loop drive supplies
that can be used to power the loop if required.
The major advantage of using separate source and
display units is that now both ends of the loop can be checked
at the same time. Both transmitters and indicators can be tested
and calibrated while connected in the process loop, or when
removed from the loop.
With an accuracy of 0.1% for Loop-Mate1 and 0.05%
for Loop-Mate2, both are suitable for all process loop applications.
Time Electronics plan to continue with the theme
of simplicity of operation for a range of SensorMates. These
will also be single function sensor simulators for thermocouples,
PRTs, millivolt/milliamp and pressure.
Each SensorMate is pocket-sized, easy to operate,
and low-cost.
