GS-2MSD-DI DMS-Data Logger Description The GS-2MSD-DI is a measuring amplifier with integrated data logger, which is suitable as a hand-held device and for stationary use. Due to its compact size, the GS-2MSD-DI fits in every bag. Data logger with SD card slot USB interface For DMS quarter, half and full bridges 0...0, potentiometric sensor 24 bit resolution sensor configurations available Battery mode Real-time clock IP version optional The sensors are connected via -pin Sub-D connector. Force sensors, torque sensors, DMS, quarter bridges, half bridges and full bridges can be connected. The measuring amplifier has integrated bridge completition for 20 ohm, 30 ohm and 000 ohm strain gauges. Active sensors with 0...0 output signal and potentiometric distance sensors can also be connected. A version of the device with protection class IP is also available. The SD card slot and the USB interface are then sealed with an additional cover. The SUB-D sensor connection and the housing seals are then reinforced for this protection class. The measurement data is saved with time stamp. Different operating modes e.g. individual value request, permanent recording, triggering per control line, min./max. mode and other settings are possible. The measuring rate can be set up to 370. Recording on SD card is possible up to 000. Up to sensor configurations can be defined and retrieved, e.g. for switching a sensor or quickly setting the measurement conditions.
