General
Two separate pressure chambers with pressure-side connection to hose nipples. Connection of ø 4 mm for each pressure chamber. Reference value (pressure difference) can be set directly. Reference value can be read off externally through the transparent hood. Precise function through special switching system in a frictionless bearing. Contact switchover is performed when the set reference value is exceeded or undershot. Complete mounting kit enclosed.
Application
The equipment is used in ventilation and air-conditioning systems, DDC. It is specially designed for monitoring air ducts, filters, drive units and blowers.
