Neuron Differential Pressure

The Neuron Differential Pressure sensor measures the differential air pressure between two ports. In addition, it also measures the ambient temperature. The sensor is well suited for HVAC systems and has an embedded magnet for easy installation on magnetic surfaces.

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

General Description

The Neuron Differential Pressure sensor can be used to monitor the pressure drop across filters, measure flow in air ducts, or monitor the pressure in HVAC systems.

The Differential Pressure sensor is compact, lightweight and available in different measurement ranges. It has high accuracy and great overpressure and burst pressure at 10 and 300 PSI.

It has a low power consumption and will operate for up to 10 years on its integrated battery.

 

Principle of Operation

The Neuron Differential Pressure sensor uses a ceramic diaphragm as its pressure sensitive element. The pressure is inferred from the piezoresistive effect in the diaphragm. A ceramic material is used in this sensor because of its excellent mechanical and chemical stability, high temperature range and good insulation. It’s also less prone to corrosion and erosion.

These sensors have good repeatability and long-term stability which makes them an ideal choice for industrial and HVAC applications.

Every 30 seconds the sensor measures the pressure and if the pressure has changed more than 10/150 Pa since the last transmission, the sensor reports immediately. Otherwise, it reports every 2 minutes.

 

Features

  • Integrated long life battery – up to 10 years lifetime
  • Built-in magnet for easy and secure fastening on the asset
  • 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

Installation

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.

Fastening
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.
