LVM-110 Voltage Output LVDT/RVDT OEM Signal Conditioner SPECIFICATIONS Low cost OEM signal conditioner Very compact, open PC board design Multiple unipolar and bipolar output options DIP switch selectable gain and excitation 2.5, 5, 8 and 10kHz excitation frequencies Zero and span adjustment potentiometers Master/slave capability Card-edge or barrier strip connections Works with very low input impedance LVDTs and RVDTs The LVM-110 is a full-featured LVDT/RVDT signal conditioner that offers excellent performance on a budget. Operating on either a 12 FEATURES or 15VDC supply voltage, the LVM-110 delivers a full range of Low cost/high performance selectable unipolar and bipolar, low noise DC voltage outputs. 3-pole Butterworth filter DIP switch selectable gain, output and Designed to be compatible with most LVDT and RVDT transducers, the LVM-110 will operate with 5 and 6 electrical connection devices. LVDT excitation frequency This versatility is due to the wide variety of selectable excitation 20-turn zero suppression & span frequencies, and a generous excitation drive current of 20mA, potentiometers allowing operation with transducer input impedances as low as 150 Ohms. The master/slave function (DIP switch selectable) allows synchronization of multiple conditioners to prevent beat frequencies and cross talk between transducers. The need for phase correction APPLICATIONS adjustment is eliminated thanks to demodulation synchronized to Position feedback systems the sum of the LVDT/RVDT outputs. High density dimensional gaging The LVM-110 is designed for easy installation, plugged into a Space restrictive installations backplane-type connector, or with individual wires connected to the Testing systems screw terminal barrier strip. Measuring less than 2.5x2.5 inches, it Integration into OEM machines can be mounted or stacked using the permanently attached threaded standoffs, or card-edge guides. All selectable operating parameters are easily accessed via two DIP switches, simplifying the gain, frequency and output setup procedure.
