Neuron PT100 HT Magnet /
PT100 HT Average Magnet

The Neuron PT100 HT Magnet sensor comes ready to use out of the box and are fitted with a magnet to enable easy installation on objects made of ferrous materials. This makes the sensor perfect for retrofit installation.

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

General Description

Neuron PT100HT Magnet read the temperature and convert it into a digital measurement.

The sensor comes with a magnet with 6kg pull force and will hold 90% of its pull at 400 °C.

Spring loaded measuring tip ensures good thermal connection to surface.

Due to wireless transmission of the signal, it is easy and timesaving to install.


Principle of Operation

The Neuron PT100 measures every third second and transmits every second minute with standard config. The sensor also comes in a version where the sensor measures every ten seconds and transmits the average of the twelve last measurements every ten minute.

Should the trigger for critical data transmission be reached between two transmissions, the sensor transmits immediately after measurement.



  • 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
  • Receive alerts as push notifications, emails or SMS
  • Easily connect the sensor to the system with the QR-code on the sensor. Ensures immediate and accurate registration in the app on your phone/PC/tablet
  • The sensor transmits data to your nearby Neuron Gateway which then again communicates with the Neuron Cloud

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.
