Low-Voltage Measurement
(0–24 mV)

The Millivoltmeter is a device designed for the measurement of very small DC voltage, converting the data into a format compatible with an Vutlan monitoring system. It allows for real-time remote monitoring of DC voltage levels in various applications, such as data centers, industrial automation, and renewable energy systems.

VT424 is an analog sensor plug-and-play sensor and can be connected to any analog port of Vutlan monitoring system.

The maximum amount of VT424 sensors connected to a Vutlan monitoring system and the maximum cable length can be extended using the "VT408 / Sensor extension unit".

Custom order:
Measured range 0-100mV

Use cases

  • Current shunts: Measure the voltage drop across precision shunt resistors to calculate current (common in battery systems, DC power, and industrial equipment).
  • Strain gauges: Read the small millivolt outputs from load cells, force sensors, and weighing systems.
  • Pressure transmitters (mV output): Some pressure sensors provide a direct millivolt output.
  • Calibration and testing: Verifying low-voltage outputs of sensors and instrumentation.
  • Bridge sensors: Wheatstone bridge-based sensors for force, torque, displacement, or pressure.
  • Thermocouples: Many thermocouple types generate only a few millivolts depending on temperature (requires proper cold-junction compensation for accurate temperature measurement).
  • Research and laboratory measurements: Measuring very small DC voltages in electronic circuits and experiments.
