Neuron Temperature IP67

The Neuron Temperature IP67 is a small and compact sensor for measuring temperature and suited for a wide range of applications. Both surface temperatures when attached directly to the object, or as an air temperature sensor in wet or dusty areas due to IP67 encapsulation. The sensor is mounted using double-sided tape or cable ties.

General Description

Temperature is a crucial parameter in many different applications, from HVAC systems and industrial process maintenance to freezers. Accurate measurement of temperature is therefore essential for maintaining optimal conditions and ensuring proper functioning of these systems.

The Neuron Temperature IP67 sensor is a high- precision device designed specifically for measuring the temperature of surfaces or air. With a wide temperature range of -40°C to 85°C and an accuracy of ±0.5°C,
this sensor is ideal for a variety of applications where temperature needs to be monitored and controlled with a high degree of accuracy.

Compact in size at just 37mm x 23mm x 14m, the sensor is easy to integrate into any system. It operates on a non-replaceable integrated battery allowing it to operate up to 10 years.

Whether you need to monitor the temperature in a warehouse, control the temperature in a refrigerator, or monitor cable temperatures, the Neuron Temperature IP67 sensor is the perfect choice for reliable and accurate temperature measurement.


Principle of Operation

In the Neuron Temperature IP67 sensor, an NTC thermistor is used as the sensing element. The thermistor is placed in direct contact with a thermally conductive surface in the IP67 enclosure, allowing it to accurately measure the temperature. The thermistor’s resistance is measured by passing a small current
through it and measuring the voltage across it. This voltage is then used to calculate the thermistor’s resistance, and from that the ambient temperature can be inferred. The Temperature IP67 sensor has high accuracy, wide temperature range, robust IP67 enclosure, and fast response time.

Every three second the sensor measures the temperature and if the temperature has changed more than 2 degrees since the last transmission, the sensor reports immediately. Otherwise, it reports every 2 minutes.

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.
