Our basic snowload probing system can be extended anytime with further optional sensors for monitoring your premises.
All sensors will send auto-notifications on exceeding customer adjusted alert levels via alert-SMS or e-mail.


Wind speed indicator:
The snowcontrol scaling-system for snowloads may be extended with an air speed indicator, adjustable to upper and lower limit values. 
On exceeding either of these alert levels you are auto-notified via SMS or e-mail.
By permanent auto-monitoring the wind regime on your flat roof, you are increasing the roof's safety and are preventing potential damage.

Technical dataWindmesser
  • Range: 0.5 - 50 m/s
  • Accuracy: +/- 3% of measured value or +/- 0.5 m/s
  • Current consumption: < 1mA
  • Environmental temperature ranges: -40 .. +70 °C
  • Safety class: IP 55





Innovative impound water sensor:
On flat roofs water often impounds on large scales, not draining off fast enough.
Also drainage deficiencies or blocked drains may lead to impounded water.
Water retentions like this should be noticed as soon as possible in order to prevent damage to the roof's structure or even structural collapse due to exceeding tolerable roof loads (according to a press article in Sueddeutsche Zeitung from Feb. 26, 2012 "Schuldach bricht ein" - School's roof collapses).
Due to our novel and innovative impound water sensor such hazardous situations can now be detected in time.

Using snow depth as additional information:

As an addition, during winter season this sensor also provides data about current snow depth on your flat roof.


Technical data

  • Ambient temperature: -40... +70°C
  • Accuracy: +/-5mm
  • Range: min. 20mm, max. probing height depends on height of installation
  • Current consumption: < 1mA
  • Safety class: IP55





Immersion probe:
Our immersion probe allows for monitoring downpipes, drainpipes and similar devices. In case of downpipes blocked by leaves rainwater quickly retains. In order to prevent potential seascapes on your roof building up considerable weight, you are auto-notified by this system extension.

Technical data
  • Accuracy: +/-0,5% v.M.B
  • Range: 0..600mbar
  • Resolution: better than 0.002% of total range


Rainfall signaler:
This extention serves as an innovative rainfall intensity sensor.
The rainwater is collected via a funnel area and led to a tilting scale. On reaching its maximum capacity, the scale tilts. Every tipping operation is captured contact-free. By applying this sensor, the precise amount of rain on your roof is captured, so that you are able to react in time in case rainfall should exceed the alert limit.

Technical data
  • Principle of measurement: tilting scale
  • Resolutio: 0,1 mm NS
  • Collecting area: 200 cm2
  • Intensity: max. 11 mm/min.
  • Ambient temperature: : -25 ... +60 °C (with heating





Laser based precipitation monitor:

Our laser based rainfall monitoring system detects and measures various kinds of precipitation like
  • hail
  • drizzle
  • rain
  • snow

as well as mixed precipitation. The sensor is able to determine nature, intensity and even the spectrum of precipitation.
