Loop wiring consists of a 2 wire
connection. With the installation of a standard 2 wire cable, installation
can be very simple. With location of the transmitter power supply next to
the measurement system; the installation of a jumper between supply - and
measurement system -; all that is required is a connection from the
transmitter + to the power supply +, and a connection from the transmitter
- to measurement channel, to complete a loop transmitter signal
connection.
This is key as other methods of
signal conditioning may require, a 3 wire or 4 wire connection between the
conditioner and measurement system, depending on the type of conditioner.
Why is this important? In addition
to the complexity being decreased, the cost of the cable decreases as
well.
The ROI-XMA
is an improved way to read sensors. Multiple sensor types. Multiple signal
ranges. High linearity. High precision. Fast response. Long transmission
distances. True analog signal conditioning, not microprocessor based A-D
conversion.
The ROI-USB
combined with the ROI-ISOV
is an improved way to isolate your reading of high voltage. Input to
output (2-way) 1.5Kv isolation. Fast response. True analog signal
conditioning.
