Magtrol's Load Monitoring Units are used for measuring load,
force and weight from signals generated by strain
gauge transducers. Specifically designed for use with Magtrol's Load Measuring Pins
and Load-Force-Weight Sensors, the LMU Series provides excitation voltage
while conditioning the bridge output signal. Each unit contains
DIP-switches and jumpers for greater flexibility and complete
adaptability. User-defined alarm limits can be programmed into
the unit, which when combined with our sensors, provides a safe
and rugged measurement system that continuously monitors for
short-circuits and interrupted signal lines. Magtrol LMUs are
specially designed for use in harsh environments and are suitable
for crane security systems.
New LMU 110
Magtrol’s LMU 110 Load Monitoring Unit is a 4-channel bridge amplifier with 4–20 mA DC current output. With 4 independent inputs and outputs, the LMU 110's sensitivity and offset are adjusted at the factory according to the transducer type and its application.

Supporting Electronics
Large Remote Displays
If a large display is required a GAC Series Remote Display (with heights ranging from 57
to 280 mm) can be used in combination with any Magtrol LMU unit.
Junction Boxes
Up to 4 LB Load Measuring Pins (full-bridge
strain gauges) can be connected in parallel to the LMU Load
Monitoring Unit, using a JB 113 (2 load pins in parallel)
or JB 114 (4 load pins in parallel) junction
box.
