Current transducers are utilized to detect the amount of current flowing through a conductor and then converts that data into a proportional electrical signal, which can be read and further analysed. A common piece of equipment utilized for this is the HAC 800-S current transducer. This article is intended to serve as a guide to the application field and working principles behind it.

The HAC 800-S is a self-contained, isolated current transducer, operating without auxiliary power. It has a measurement range of 0.1mA to 20A and a response time of 5 ms, making it ideal for many diverse applications.

The functionality of the HAC 800-S comes from the innovative design of a linear Hall effect element. Utilizing the magnetic field around the conductor, a current is generated that can be detected and translated to a voltage. This voltage is then used by the microprocessor to convert the measurement into a direct proportional electrical signal, which is then outputted.

The HAC 800-S is primarily used in the industrial sector to detect the current flow in motors, lighting, and heating or air conditioning systems. The device can also be used to measure low currents in order to check for grounding faults. This makes it ideal for applications such as troubleshooting problems with insulation in electrical connections, diagnosing to amplifier operation, and detecting arcing in electrical switches.

The fact that the device is entirely self-contained and requires zero auxiliary power makes it extremely desirable for portable applications, such as monitoring current levels when testing switch boards, diagnosing wiring faults in electric vehicles, or measuring current levels being produced by solar panels. The flexibility of the device makes it capable of providing data on a variety of current levels.

The HAC 800-S boasts a very sophisticated design, and much of its functionality is due to its circuitry composed of a linear Hall effect element, an amplifier, and an Analog-to-Digital (A/D) converter. The Hall element measures the existing magnetic field around the conductor and generates a signal, which is then amplified and converted into an accurately scaled voltage.

This, in turn, is converted into a digital signal by the A/D converter. The result is an orderly digital representation of the measurement taken, which can then be read by the user. The device is also highly resistant to temperature and EMI, which results in extremely accurate measurements.

In short, the HAC 800-S current transducer is an extremely versatile and reliable device for a variety of applications. From industrial applications, to portable applications, to special tests and measurements, this device offers a precise solution to many current measurement requirements.
