Neuron mA Digitizer /
Precision mA Digitizer

The Neuron mA Digitizer converts your analogue signal into a digital measurement. Integrated battery ensures up to 10 years of battery life. All measurements are easily accessible from web, app or API.

Experience how easy it is to get started and the huge benefits of our simple and practical IoT solutions.

General Description

The Neuron mA Digitizer is a battery-powered device that can convert an analogue 4-20mA industrial signal into a digital signal. The device then transmits the converted digital signal via a wireless radio signal.

It is designed to be used in industrial environments, where the wireless transmission capability makes it easy to collect data from remote locations and the battery power makes it convenient to use in areas where power supply is not available.

The digital output signal can be configured in the app depending on the user need, where 4 mA may represent 0 Bar and 20 mA may represent 10 Bar for example.

The sensor provides an accuracy of up to 0.1% of full scale, and a resolution of up to 0.003 mA.


Principle of Operation

The Neuron mA Digitizer reads the analogue DC-current signal and converts it into a digital measurement. Due to wireless transmission of the signal, it is also easy and timesaving to install. The sensor is a versatile device that can be used in a wide range of industrial applications.

Some common use cases include: Digitizing 4-20 mA control loops, make analogue sensor systems “smart” by sending its data to the cloud and condition and remote monitoring.

Every 10 seconds the sensor measures the current and if the current has changed more than 2 mA since the last transmission, the sensor reports immediately. Otherwise, it reports every 2 minutes.

The product is available in two versions, mA and Precision mA.



  • Integrated long life battery – up to 10 years lifetime
  • Continuous measurement and instant alarm
  • Adjustment of parameters such as measurement frequency on request
  • Define your own alarm levels in the Neuron app

Neuron sensors are ready for use out of the box and will start logging data after registering the sensor in the app. Even though Neuron sensors deliver great range and long battery life, following some simple guidelines for mounting of the sensor and gateway can greatly improve signal coverage and lifetime of the sensor.

To ensure optimal antenna performance and signal strength, the sensor should be placed elevated with some distance to fixed objects. Keep in mind that RF-signals are greatly affected by close metallic surfaces.

For sensors with an external antenna, the antenna should be clear off the metallic surface.

For sensors operating in environments with greatly varying temperatures, care should be taken to avoid putting the sensor in unnecessary stress. Very high or low temperatures will affect the battery life and the signal strength of the sensor. While some sensors must be close to the source of heat or cold, other sensors have external probes which allow the sensor to be placed at a distance.

The small, compact blue Neuron sensors are fitted with fastening holes for use with cable ties. The sensors are also delivered with double-sided tape that may be used for fastening of the sensors.

All the black Neuron sensors, like the Neuron IR380 and Neuron Vibration, are fitted with a strong magnet at the back for easy fastening. If there is no magnetic surface, then double-sided tape is a good solution.
