LOAD MONITORING UNITS

ELECTRONICS

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 industrial 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 (IP 65 protection class) and are suitable for crane security systems. Magtrol’s AN Series Signal conditioners are used for processing and displaying measurements from signals generated by transducers (weight, load, pressure, torque, etc.) that use standard strain-gauge bridges such as Magtrol’s load measuring pins, load-force-weight sensors and strain transducers. Suited for indoor use, the AN Series provides selectable input ranges and excitation voltages to accommodate cells of various types and sensitivities
