Conductive Sensors Level Probes Types VT, VTI • Excellent resistance to chemicals • Teflon housing • 1 to 4 electrodes • Isolated (teflon) or unisolated electrodes • Cable connection • 1 1/2” pipe thread according to ISO 228/1-Gx” Product Description Ordering KeyVTI 4 Levelsensorfor measur- ing the level of conductive liquids, i.e. max./min. control of charging for discharging. The function is determined by the amplifier relay used. The sensorsaredeliveredwith standard length electrodes - these are cut off to suit the application. The teflon hous- ing makes the sensor excel- lent for use in rough environ- ments. Type Housing material Isolated Number of electrodes Type Selection Pipe threadElectrodeOrdering no.
