• 4-20mA Current Sensors: Current sensing products with current loop outputs for PLCs, controllers, displays and monitoring systems.
• 0-10V Current Sensors: Current transducers with voltage outputs for compatible analog input and display applications.
• AC Current Sensors: Sensors used to monitor AC load current in motors, pumps, fans, machinery and electrical circuits.
• DC Current Sensors: Sensors used for suitable DC power, battery, solar, control and electronics monitoring applications depending on current availability.

Current Sensors for Motors, Pumps & Control Systems

Current sensors are commonly used in pump systems, fan systems, motor control panels, machinery, power monitoring, fault detection, load monitoring, automation systems, energy projects and industrial electronics. They can be used to detect whether equipment is running, estimate load, monitor current draw or provide a signal to a PLC or display.

Always check the current range, AC or DC suitability, output signal, supply voltage, conductor size, measurement method, isolation, accuracy, frequency range, mounting style and wiring requirements before ordering.

Current Transformers, Current Transducers & Monitoring Signals

Current transformers are commonly used for AC current measurement because they can often measure current without directly breaking the power conductor. Current transducers may provide standard output signals such as 4-20mA or 0-10V, making them useful for PLCs, panel meters, data loggers and control systems.

Frequently Asked Questions

What is a current sensor used for?

A current sensor is used to measure electrical current and convert it into a signal that can be used by a controller, PLC, panel meter, alarm or monitoring system.

What is a current transformer?

A current transformer, or CT, is a sensor used to measure AC current by detecting the magnetic field around a conductor. It is commonly used for non-invasive current monitoring.

What is the difference between a current transformer and a current transducer?

A current transformer usually provides a proportional AC signal for current measurement. A current transducer often converts the measured current into a standard signal such as 4-20mA or 0-10V.

Can current sensors be used for motor monitoring?

Yes. Current sensors are commonly used to monitor motors, pumps, fans and machinery to detect running status, load changes, overload conditions or abnormal current draw.

Can you help me choose the right current sensor?

Yes. If you are unsure which current sensor suits your application, contact AuscomTech with your AC or DC supply type, current range, conductor size, output signal, supply voltage and monitoring requirements.
