28 cze 2024 · The transducer regulates the flow of current through the wires at 4 to 20 mA, where 4 mA represents a live zero and 20 mA represents the maximum signal. A 0 mA signal signifies a break in the loop. The data acquisition device measures the regulated current flow.
The device is a split core current sensor with a 24mm opening. It is able to sense up to 250 Amps of AC current input and control a 4-20 mA DC current loop on the output. This loop can be used for power measuring or monitoring purposes. The device comes with a self-locking mechanism.
The XTR117 is a precision current output converter designed to transmit analog 4-mA-to-20-mA signals over an industry-standard current loop. The device provides accurate current scaling and output current limit functions. The on-chip voltage regulator (5 V) can be used to power external circuitry.
23 paź 2024 · The remote transducer on the left regulates the loop current in proportion to the quantity being measured, with 4mA representing a zero reading and 20mA full scale. The sensor converts the current back to a voltage for display or other use.
4-20mA overview. 4mA represents 0% input level. Allows up to 4mA to power external input circuitry. 4mA zero level allows under-scale settings and fault detection. 20mA represents 100% input level. Over-scale can also be used to detect fault conditions.
The AD693 is a monolithic signal conditioning circuit which accepts low-level inputs from a variety of transducers to control a standard 4–20 mA, two-wire current loop.
Universal current transducer, for measuring AC, DC, and distorted currents, 0 ... 100 A input current, 4 ... 20 mA output
