The digital VFD Grundfos Direct Sensors™ measure temperature and relative pressure with a single measuring element and then transmit the measured values directly via the RESOL VBus® protocol. They can be optimally used for leakage and overpressure monitoring. Grundfos Direct Sensors™ can be used in both aggressive media and domestic water and are therefore ideal for use in solar thermal and heating systems.
