Contactless, precise AC/DC Current Monitoring

AC DC current sensor.jpg


System description


Vutlan offers contactless, precise open-loop AC-current and DC-current sensors. They measure AC and DC currents and provide electrical isolation between the circuit being measured and the output of the sensor (the primary current is measured without electrical contact with the primary circuit, providing galvanic isolation). Vutlan transducers and meters provide analog output signals (0 - 5 V) compatible with most PLCs, data loggers, and SCADA systems. This provides a solution to knowing how much AC current is flowing through a wire without any physical intervention. In some cases during a system debug, determining whether or not an AC current is flowing through the wire is required. Used for:

  • Indicate overcurrent alarm conditions
  • Determine the load characteristics by monitoring the sourced current
  • Indicate alarm conditions when no current is flowing through the monitored wire
  • Monitor a phase of power for debugging, data logging or both
  • Additionally for DC current indicate the direction of the current

AC Current Monitoring

100A transducer is used for the measurement of AC current. The system interface allows you to assign a transducer and to introduce the function data conversion. VT407 / HAT transceiver can be used together with HAT-100Q1 to convert data into the format of the Vutlan monitoring system. The transducer consists of a plastic housing with an open/closed AC current loop and 4 pins terminal connector. The current transceiver is a simple plastic case with 4 pins input, power 12V socket, and analog 0-5V RJ12 output. Full description, technical specifications, and manual are available on the product page: HAT-100Q1 / AC Current Transducer and HAT-100Q1 / AC Current Transducer



Current monitoring in AC power circuit.jpg

Example: Measuring current in AC power circuit

Sensor for measuring current in 230V and 110V installations using Vutlan open-loop contactless hall sensor and a converter enables you to create an early warning system against overloading the electricity supply or individual lines.



Equipment life prediction using current sensor.jpg

Example: Life prediction of equipment

As the electric elements age in the equipment, its resistance also changes. By measuring the current drawn by the element using Vutlan current transducer the resistance of the element can be determined and compared against a known aging characteristic. When the element reaches a predetermined state it can be replaced before failure.

Switch off equipment before it overloads.jpg

Example: Turn off equipment before it overloads

Set up logic using the Vutlan monitoring system to turn on the equipment on schedule using relays. Create a logic rule to turn off the equipment in case the feeding current reaches an alarm point before the equipment overloads.

Equipment jam notification and sensing.jpg

Notify personnel and control center of equipment jam

In case of low current, notify personnel by switching on the alarm beacon and notifying the control center using an E-mail, SMS, Syslog, Event log, SNMP Trap, or SNMP Get.


DC Current Monitoring

The transducer is used together with the HOS-100Q1 DC Hall current transducer for sensing current and converting data into the format of the IP monitoring system. HOS-100Q1 can sense in which direction the current is flowing, this is an ideal solution for monitoring UPS and Battery charging and life prediction. The system interface allows you to assign the current meter and to introduce the function data conversion. The transducer consists of a plastic housing with an open/closed AC current loop and 4 pins terminal connector. The current transceiver is a simple plastic case with 4 pins input, power 12V socket, and analog 0-5V RJ12 output. Full description, technical specifications, and manual are available on the product page: VT406 / DC HOS sensor transducer and HOS-100Q1 / DC current transducer



DC current monitoring (UPS, Battery).jpg

Example: Monitor battery charging or UPS

If the hall sensor is installed in such a way that its arrow, drawn on it, points towards the battery, then: If the battery is charging, the sensor shows that the current is ”+”; If the battery is discharging, the sensor shows that the current is ”-”.
