Strain gauge amplifier

To handle the full range of strain gauge measuring tasks, HBM has launched the MX1615 measuring amplifier module with universal inputs. The module enables the connection of up to 16 strain gauge channels in a variety of configurations including full-, halfand quarter-bridge with both 3-wire and patented Kreuzer 4-wire circuit.

The module enhances measurement flexibility because all channels can also be used to record standardised voltage signals of ±10V as well as temperatures with a PT100 sensor. Each channel can be individ - ually parameterised and is equipped with 24-bit A/D converters.

The data rate of 19.2kHz and the maximum bandwidth of 3kHz per channel ensure that the MX1615 covers a wide analysis range. The excitation voltage of the strain gauge channels can be selected for each channel as a carrier frequency or DC voltage.
