Available now from Bestech Australia , GSV-3 series measuring amplifiers for sensors with strain guages can be adapted for almost any application which involves strain gauges.

The core of these measuring amplifiers is formed by a printed circuit board of only 30mm x 15mm, which already provides all the essential functions of a modern measuring amplifier, including:

  • analog output
  • 16 bit A/D-transformer with serial interface
  • adjustable digital filter
  • threshold output
  • trigger input; and
  • taring function.
The 16-bit A/D transformer in these measuring amplifiers operates with an internal measuring frequency of 10kHz (maximum).

The housed variants contain support boards, which provide different interfaces and data protocols.

The GSV-3LS measuring amplifier features a low power consumption of less than 24mA, with maximum data frequency using a 350 Ohm strain gauge. Other features of these measuring amplifiers include high data frequency of up to 1220 measured values per second, high measuring resolution and programmable filters.

Outputs include an analog output of 0-5V, two digital in/outputs, and one switching output, configurable to threshold monitoring or as a window comparator. A USB version is also available.

The analog output is provided with automatic zero balancing, triggered by a control impulse (TTL level up to 30 volts), and the filter of the analog output has a cut-off frequency of 1250Hz.
 
The model GSV-3AS measuring amplifier is optimised for a supply voltage of 2.4 volts, allowing it to be operated with AA or AAA batteries. Operation with a supply voltage between 8 volts and 30 volts is also a possible option.

Serial output for the GSV-3AS measuring amplifier is via either a standard RS232 or TTL-RS232. For operation with a data modem an extensive command set is provided, such as a shift between transceiver and receiver, and a sleep-function for reduction of power consumption with low scanning frequencies.
