Description
The Magtrol Load Monitoring Unit is specially designed for
strain gauge transducer applications. Specifically developed
for use with Magtrol load measuring pins and load-force-
weight sensors, the LMU Series provides excitation current
and amplifies the output signal of full-bridge strain gauges.
Load Monitoring Units are flexible and fully configurable
due to DIP-switches and jumpers which allow the unit to
be easily installed—no solder connections are required. The
level detectors and the outputs can be dedicated either to the
MoDel coMparison

full-bridge input, to the voltage input, or to the sum of both
(see "Application Selection" at the top of page 3). A built-in
auto-diagnostic system detects any short circuits or signal line
failures, thus allowing the system to be used in applications
where safety is important. If a problem is detected, both
relays are deactivated and the output voltage (respective
current) changes to >10 VDC and >20 mA.
The LMU is fully compatible with European Community (CE)
standards. Its IP 65 aluminum housing allows the system to
be used in harsh environments. Using SMD (surface mounted
device) technology, the LMU allows the maximum performance/
price ratio for strain gauge transducer monitoring.
