2 models:
  • SPRD SIGFOX 500: measuring range 0-500Pa.
  • SPRD SIGFOX 500E: measuring range 0-500Pa + BDEZ mechanical vacuum input.

SIGFOX communication:

  • SIGFOX network, low speed and very long range cellular wireless network with national coverage.
  • Economical alternative technology to wired / 3G solutions for surveillance or remote reading.
  • Allows the supervision of VMC installation (residential or tertiary).
  • Periodic transmission of pressure data.
  • Communicating differential pressure probe via the SIGFOX low flow wireless network.
  • NFC tag for complete identification of the probe.
  • Pressure measurement by a high precision tropicalized electronic pressure sensor.
  • Activation / deactivation by magnet supplied.
  • Pressure measurement every hour.
  • Transmission once a day at a fixed time: minimum, maximum and average pressures over 24 hours.
  • Immediate transmission if a threshold is crossed.
  • Transmission when activating or deactivating the sensor.
  • Supplied with 2 pressure taps and 2 tubes of 2 m length connected for connection to the box or to the duct (saving labor on site).
  • SPRD SIGFOX 500E supplied with an input for connecting a BDEZ type mechanical pressure switch (cable gland supplied). Triggering the pressure switch forces an additional measurement and activates an alarm report. Particularly suitable for monitoring VMC Gas installations thanks to the connection of the mechanical depressostat making it possible to respond to COPREC.
