MP1000 and MP2000 Series Single and Dual Channel LVDT Readout/Controller ® The Schaevitz microprocessor-based LVDT indicator and set-point controller is designed for industrial and process control applications utilizing any LVDT/RVDT-based measurement device. In addition to displaying real-time readings of LVDTs and gage heads, these single and dual- channel instruments display MIN, MAX and TIR values. A dual channel model is also capable of A+B and A-B functions. A 16-bit analog-to-digital converter provides high speed performance and resolution. An RS-232 output will communicate data to any standard PLC or computer serial port. MP Series readout/controllers are packaged in a 1/4 DIN case with a back-lit, super-twist LCD display. (Units are splash-proof when mounted with a gasket.) New Features ❏Simultaneous dual channel display ❏Opto-isolated setpoint outputs ❏Digitally scaled analog output ❏Digitally controlled analog zero suppression ❏CE approval pending Setpoint Control ❏Programmable digital filtering Four user-programmable digital setpoints are used to monitor any parameter. Any combination of high or low setpoints may be selected. A high and low hysteresis value Applications from 0 to 200 display counts can be programmed for the setpoints. Decimal points are programmable via the set-up❏LVDT-based weighing systems menu. ❏RS-232 data collection for SPC Auto-Calibration ❏Roller gap control A front panel pushbutton auto-zeros (tares) over the ± full scale range. Auto-calibration eliminates calculation of slope ❏Concentricity gages or gain factors. Calibration and setup parameters are stored in nonvolatile memory for retention on power down or ❏Tank level control interruption. ❏Part classification Readings A two-line alphanumeric display provides user-friendly word prompts for easy pushbutton system setup and MP Series Accessories monitoring of in-process measurement parameters. ❏Relay option board • Current value • Min/max❏Lab stand/bench mount • A+B (sum of two channels) ❏Rack adpator holds up to four MP Series • A-B (difference of two channels) Readout/Controllers (see page 121) • TIR (Total Indicated Runout) Outputs A real-time scaled analog output, proportional to the digital readout is provided for each LVDT channel. An RS-232 output is provided for data transfer to a computer at 600 to 19.2K baud.
