The ÖWWG 3 oil/water water alarm unit consists of a fail-safe, self-
monitoring control unit with periodic self-test and a probe. The
control unit and the probe are connected by means of a two-wire
signal cable with a maximum length of 50 m.
Depending on the order, ÖWWG 3 features an optional EnOcean
®
wireless module. Products without an EnOcean® wireless module
can be retrofitted.
Probe
A PTC thermistor is contained in the probe head. During operation,
the PTC thermistor is heated and can distinguish between gaseous
and liquid media due to the different heat dissipation. The probe is
equipped with a 2-wire signal cable (3.2 m).
The probe is a wearing part and must be replaced after no more than
ten years.
