Product description
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.
Applications
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.
