The Neuron Dry Contact is a small and compact sensor for detecting Open/Closed electrical contact in potential free loops. The sensor can be used in humid areas due to IP67 encapsulation.
General Description
The Neuron Dry Contact sensor is an electronic device that detects the presence or absence of electrical contact in potential-free loops.

The sensor is designed to be used in a wide range of industrial and commercial applications, automation systems, and process maintenance. They are typically used to detect the position of mechanical parts, such as doors, valves, and machine components.

The Neuron Dry Contact sensor has a wide operating range from -40 – 85 °C and has a robust IP67 enclosure for mounting in rough conditions.

The sensor has an integrated battery which will last up to 10 years**.



Principle of Operation
The Neuron Dry Contact consists of a pair of wires that measures the electrical potential between them. When the two wires are connected through the valve, door or similar, an electrical circuit is completed, signalling that the contact has been activated. Conversely, when the contact points are separated, the circuit is open, signalling that the contact has been deactivated.

Every three second the sensor measures the loop contact and if the loop status has changed since the last transmission, the sensor reports immediately. Otherwise, it reports every 2 minutes.



Features
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
