Precision C Series Signal Conditioning Modules

Precision Filters’ family of high-performance signal conditioning modules add unprecedented function and performance to measurement systems built on National Instruments™ C Series platform.

Choose from five different modules to measure charge, bridge, dynamic strain, IEPE or voltage-based sensors. With no software to write, you can build a turnkey signal conditioning system front end using the low cost NI™ Ethernet RIO chassis controlled by PFI’s stand-alone Graphical User Interface. Or using the supplied LabView™ module driver VI, you can combine PFI’s signal conditioner modules with proven NI voltage input A/D modules to build a complete high-performance sensor measurement system in any CompactDAQ or CompactRIO chassis. Choose charge, voltage, bridge or dynamic strain modules. Count on PFI’s dependable signal conditioning technology for precise measurements. All modules are fully programmable and are equipped with Precision Filters’ Test Input for inserting calibration signals at the module input, allowing for full end-to-end verification. Real time sensor parametric health is continuously measured and reported “on-the-fly”.
