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.
