Dataforth Corporation of Tucson, Arizona, has introduced the latest addition to its
extensive line of miniature 8B isolated analog signal conditioners: the
8B43.
This input module interfaces to DC linear voltage displacement transducers (LVDT) which operate on a 10V excitation voltage and up to 20mA of excitation current.
The
8B43 family includes 10 different modules with input ranges from -1V to +1V through -5V to +5V. Each module isolates, filters, and amplifies a voltage input signal, then provides an analog voltage output. Like all 8B modules, the 8B43 is an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system.
Specific 8B43 DC LVDT applications have included measuring soil sample deformation under load to determine soil strength, controlling pill weight and thickness in making tablets from medicinal powder, continuously monitoring fluid levels as part of a leak detection system (using a hydraulic oil compatible module) and replacing limit switches to ensure higher resolution on bottle inspection machinery.
Since Dataforth introduced the 8B signal conditioner in 2005, the line has expanded to 19 family groups and 123 different models. All 8B modules provide Instrument Class performance in a miniature 1.11” x 1.65” x 0.4” (28.1mm x 41.9mm x 10.2mm) housing. Their small size makes them ideal for embedded and portable applications.
