DPE12
DPE12_010P
Water detector
Application:
Water level detection for monitoring tanks, rivers, overflows…
Usable in clear or turbulent water.
Principle:
Water detection is achieved by measuring electrical conductivity between a central electrode and the sensor body. The output signal is normally held low.
When conductivity is sufficiently high (presence of water), the output signal voltage is brought to a high level.
Mechanical characteristics:
| Body and electrode: | 316L stainless steel |
| Cable: | 2 conductors 0.22mm² + capillary under shielding, PVC or reinforced PUR sheath with Kevlar depending on length. |
