LOAD MONITORING UNIT 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 LMU 21X Series are specifically designed to work with MAGTROL's Load Measuring Pins. The LMU 209 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 GAD Series and AN Series signal displays. FEATURES ▪ Signal-conditioning of strain gauge sensors ▪ Very large zero-adjusting range ▪ Universal input ranges from 0.5 mV/V to 4 mV/V ▪ Two calibrated outputs: voltage and current ▪ Selectable bridge supply voltage ▪ Polycarbonate housing for mounting on DIN-rails or aluminum housing available for harshness applications ▪ Frequency Response from 0 Hz to 3 kHz (-3 dB) Fig. 1: LMU 209 - Polycarbonate housing DESCRIPTION The LMU 209 is a versatile strain gauge amplifier, designed for signal conditioning and interfacing low level signals to programmable logic controllers (PLCs) or any control unit with analog inputs. The LMU 209 features both voltage and current-type outputs with life zero. Due to its integrated DIP-switches, the amplifier can be easily configured to the desired input ranges. This modularized amplifier is ready for snap-on mounting to DIN-rails. All wires are connected to screw terminals. Stuffing glands: ø cable: 6-10.5 mm Aluminium housing NOTE: 3D STEP files of most of our products are available on our website: www.magtrol.com ; other files are available on request.
