Absolute Process Instruments API4058G Bridge Transmitter

Absolute Process Instruments API4058G Bridge/Strain Gauge/Load Cell Transmitter is a field-configurable signal conditioner that converts a raw strain-gauge, bridge, or load-cell signal into a stable DC output for control systems. It accepts a Bridge/Strain Gauge/Load Cell input from 100 Ω to 10,000 Ω with sensitivities from 0.5 mV/V to 120 mV/V, and it uses an excitation supply of 1–10 VDC. On the output side, it provides 0–1 V to ±10 V or 0–2 mA to 4–20 mA (sink or source), with a non-isolated output relative to the input. The API4058G is designed for quick field configuration, offering hundreds of input/output ranges and removable plugs for fast installation, marketed as “One Minute Setup for Hundreds of IO Ranges.” Power options vary by model, with a standard 115 VAC variant and other configurations supporting 85–265 VAC or 60–300 VDC, and the product family includes field-configurable excitation voltage and sensor mV/V ranges. Common applications include load-cell weighing and force measurement, strain-gauge monitoring, and cargo/container weighing systems such as container weighing on dockside cranes. This combination of flexible input ranges, programmable output scales, and adjustable excitation makes the API4058G suitable for integration with PLCs, DCS, or data-acquisition systems in industrial environments.
