measurement amplifier - Velomat Messelektronik - #1

The measurement amplifier VMV-0024 is used by the networking of sensors such as Force Transducers, Strain LinkTransducers and Load Cells via the „ ControllerArea Network" (CAN).

The measurement amplifier edited the little analogous voltages of the strain gauges (dms) sensor near and you can be transferred without interference over large distances and in real time (e.g. central computers, data acquisition, data logger).

With dimensions of only 64 mm x 58 mm x 34 mm in the robust aluminium diecast box (IP66) the VMV-0024 offers excellent performance data for the strain gauge measuring technique such as:

• sampling rate of 10 kHz

• resolution of 16 Bit

• galvanic decoupling ofnetwork at low installation size.

The measurement amplifier is a universal amplifierforthe measuring data recording with its characteristics and adjustment possibilities. The measurements can in a decentralised system be "condensed" e.g. by the choice of FIR and median filters. The individual value query and sending with an adjustable, continuous data rate just are possibly as the external Triggerung or sending readings event-drivenly.

The voltage supply via 12 V or 24 V DC onboard power supplies is part as well to programm such as up to two threshold outputs and one analogous monitor output with 0 - 5 Volt of output voltage.
