IoT (Internet of Things) => Devices with SRE connect control can be remotely controlled
and monitored with any Internet-enabled computer, mobile phone or tablet.
For power regulation, the negative pressure unit is supplied with a control via a touch
display to measure and regulate the negative pressure and / or the volume flow.
The negative pressure is measured between the containment area and a reference point
to be defined (adjacent rooms) and kept at the set point value by continuous speed
control of the electric fan.
The volume flow is measured in the device and kept at the set point value by continuous
speed control of the electric fan.
Likewise, a manual control is also possible.
A filter sensor monitors the particle concentration in the exhaust air and triggers an
optical and acoustic alarm if a value of ca. 100 particles per liter is permanently
exceeded.
A necessary filter change is shown on the display.
