Analog signal conditioner LMU series

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 full-bridge input, to the voltage input, or to the sum of both. 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 V DC 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. Features For use with full-bridge strain gauge transducers (sensitivity 0.5 to 4 mV / V) Voltage input for load summation or for individual use (without sensor) Provides continuous detection of signal line failure and short circuits («OK» signals) Includes integrated test equipment (B.I.T.E.) with continuous power supply monitoring Compatible to CE Standards IP 65 aluminum housing
