ME-Meßsysteme GmbH Neuendorfstr. 18a DE-16761 Hennigsdorf Mail info@me-systeme.de Web www.me-systeme.de Description The measuring amplifier GSV-3BT supports wireless data acquisition with strain gauge-sensors. The GSV-3BT can be used for the connection of Straingage-fullbridges and halfbridges. For quaterbridges 350 Ohm there is a possibility for connection in three-wire technique. The data transmission is via Blutooth Standard 2.0+EDR with Serial Port Profile (SPP). The range is up to 20m in buildings and. up to 100m with visual connection. For a receiver a commercial Bluetooth-Dongle with...

The graphic shows the resolution with 1 m connecting cable, measuring range ±2mV/V, FIR filter switched off. Connector pin assignment Note: The antenna may not be shielded by conductive materials or liquids. The status LED indicates whether a Bluetooth connection exists. Connectors on the...

ME-MeBsysteme GmbH Neuendorfstr. 18a DE-16761 Hennigsdorf Mail info@me-systeme.de Web www.me-systeme.de Wiring diagram for quarter and half bridges to GSV-3BT Quarter bridge Half bridge Table 1: Wiring diagram for quarter and half bridges to GSV-3BT The DMS full bridge is connected to the pins 1,2, 3, 4 (jumper open), the half bridge to the pins 1, 2, 3 (jumper closed) and the quarter bridge to the pins 1, 3, 11 (jumper closed). The calibration of the measuring amplifier is valid for a full bridge with 350 ohm. The internal supplement resistors R1 and R2 are 10 ohm and R4 is 350 ohm....

ME-MeUsysteme GmbH Neuendorfstr. 18a DE-16761 Hennigsdorf Mail info@me-systeme.de Web www.me-systeme.de The measuring amplifier is configured to the rpm measurement by selecting the unit rpm. The measured values are always transmitted in text format for GSV-3BT RS. The scaling of the rpm input is fixed at 20000 and cannot be changed. The number of magnets that generate pulses at the hall sensor can be set using gsvterm.exe. For this purpose, the menu item 'Special settings' is on page 2 of the programming interface. A maximum of 100 measured values/s are transmitted, the internal sampling...

ME-MeUsysteme GmbH Neuendorfstr. 18a DE-16761 Hennigsdorf Mail info@me-systeme.de Web www.me-systeme.de Figure 4: Wiring diagram for GSV-3BT QB for asymmetrical full bridges Strain gauge full bridges are partially supplemented asymmetrically with series resistors to balance the output signal and compensate for the temperature drift. The R1 and R2 resistors of the GSV-3BT QB supplemental circuit then cause an offset that in extreme cases can no longer be adjusted. In this case, the centre tap of an additional 10 kOhm voltage divider must be connected to + Ud (terminal 3). Connector pin...
