API 4058 G Series Bridge/Strain Gauge/Load Cell Transmitters

The API 4058 G accepts a strain gauge, bridge, load cell, or a summed input from up to four sensors, and provides a proportional, non-isolated DC voltage or current output. It includes filtering and processing to allow effective use of lowlevel transducers in the noisy environments found in industrial applications. The output is not electrically isolated. The built-in 115 mA bridge excitation power supply generates a stable source of excitation voltage to drive from one to four 350 W (or greater) bridge type sensors such as load cells, pressure transducers and strain gauges.

The API 4058 G amplifies and converts the resulting millivolt signal into the selected output. Input, output, excitation, and zero offset are field configurable, via external rotary and slide switches. Common ranges are on the module label. An offset switch is standard for applications requiring cancellation of sensor offsets or non-zero deadweights (taring). Zero and span potentiometers allow calibration of the output.
