Load Monitoring
Units (LMUs) |
    |
| |
| 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. |

| 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. |

Large Remote Displays
If a large display is required a GAD Series Remote Display (with heights ranging from 57
to 400 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. |
