Modules and transducers
80 A03031_24_E00_01 HBM: public QuantumX
8.2 MX840/A/B universal amplifier
There are three MX840 generations:
S MX840: 2008 version
S MX840A: 2011 version
Function upgrade:
- Resistive half bridge
- Ohmic resistance
S MX840B: 2015 version
Extended function:
- IEPE transducers
- Resistive bridge with DC bridge excitation voltage (along with carrier
frequency)
- Decimal rates (switchable)
- Ethernet‐based synchronization via IEEE1588:2008 (PTPv2)
- 40 kS/s sample rate per channel, 7.2 kHz bandwidth
The MX840B universal amplifier provides 8 channels. Every channel supports
over 15 different transducer technologies. The pin assignment of the 15pin
DSUB15HD connector with the respective transducer technology or function
is identical for all amplifiers using DSUB15HD. All measuring channels are
electrically isolated from one another and from the mains. When using the ad
justable transducer excitation, electrical isolation from the supply voltage of the
amplifier is not required.
