The NI ‑ 9237 module has all the signal conditioning functions required for the simultaneous supply and measurement of up to four bridge-based sensors. The module enables strain or load measurements without a phase delay between the channels. Due to the isolation up to 60 VDC and the transient isolation up to 1000 Veff, the module largely reduces the susceptibility to common-mode voltages and increases the operational safety. The NI ‑ 9237 can be programmed to use half-bridge and full-bridge sensors with an integrated excitation current source. The four RJ50 connections enable direct connection to almost all torque and load cells as well as individual cable assemblies that can be implemented with just a few tools.
