General Information on CellMite Digital Signal Conditioners:

The Model 4336 CellMite Quad AC/DC is a 4-channel intelligent digital signal conditioner that connects directly to two AC LVDT transducers and two DC strain gage force transducers and provides direct digital data input into the serial port of a standard PC. Precision AC sine wave excitation voltages to power the LVDT's and precision DC excitation voltages to power the force strain gage bridges are generated by the unit. Internal signal conditioning with filtering is applied to all channels and the digitized data is sent in serial form to a standard PC.

The Model 4336 also simultaneously generates two +/- 10V analog outputs; one that tracks a user selected LVDT channel and one that tracks a user specified force channel. When used in combination with the CellView Multi-Display GUI software, a complete data acquisition system is formed with synchronized data storage of all channels in an Excel compatible file, and real-time simultaneous viewing of all channels utilizing up to 8 user specified software displays.

The Model 4336 CellMite Quad AC/DC independently compensates each channel's transducer nonlinearities using its integrated 6-point calibration capability not found in standard signal conditioners. The unit has full range tare capability for the LVDT and strain gage force channels, and dual internal precision shunt resistors for the force channels.

The Model 4336 features include nonvolatile memory for parameter and calibration storage, the ability to select between 3 stored LVDT calibrations for the two LVDT channels, and the ability to select between 3 stored force transducers for the two strain gage force channels. Also featured are multi-point and mV/V calibration, remote sense excitation, 24-bit internal resolution with 16-bit analog output, and RS232 serial data output that is compatible with off-the-shelf serial to USB converter cables.

CellView Multi-Display Software Features:

• Turnkey simultaneous data acquisition system.
• Supports mix and match usage of LVDT and strain gage channels.
• Ability to define 8 simultaneous data displays from multiple channels.
• Save data, calibration, and sensor test information to Excel spreadsheets.
• Guide user through sensor calibrations.
• Ability to select and name individual LVDT and strain gage channel sets.
• Tare and reset peak and valley for the sensors.
• Save/Load units and sensor setup information.
• Set output data with user defined 5th order polynomial function.
• Setup a test to start and/or stop automatically with user selectable trigger events and delayed triggering.
• Multi sample rate data acquisition via user definable data logging profile.
• Statistics and comments embedded in data log files.
• User programmable analog output voltages for LVDT and strain gage sensor sets.
• Units on In, Cm, mm, %, Lb, Kg, mV/V, and User Defined.
