Precision Filters

Precision Filters, Inc. (PFI) offers a complete line of bridge and strain conditioners to measure static or dynamic strain (including high temperature strain) or any bridge type transducer including pressure sensors, piezo-resistive accelerometers, load cells and more. Choose from our line-up of four and eight channel cards with performance to match your requirements. PFI's Balanced Constant Current™ technology is the industry's best technique to measure dynamic strain, even in harsh environments, and uses only a two-wire connection to the gage. The circuit is insensitive to changes in lead resistance with temperature. Because the circuit is balanced, the differential input amplifier rejects noise pickup in the leads. Below are just a few of our recent innovations.
