MAGTROL's LMU-Load Monitoring Units are signal conditioners for strain gauge sensor applications. They provide the excitation voltage, amplify the output signal, and incorporate overload protection. The LMU210 Series are specifically designed to work with MAGTROL's Load Measuring Pins. The LMU209 is versatile and designed for conditioning and interfacing low amplitude signals to industrial programmable logic controllers (PLC). The LMU conditioners can easily be connected to the GADSeries and ANSeries signal displays.
The Magtrol Load Monitoring Unit is specially designed for strain gauge transducer applications. Specifically developed for use with Magtrol load measuring pins and load-forceweight 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 full-bridge input, to the voltage input, or to the sum of both (see "Application Selection" at the top of page 4). 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 >10VDC and >20mA.
The LMU is fully compatible with European Community (CE) standards. Its IP65 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.
