ZFD Fog Detector
ZFD
The ZFD is a fog detector that measures atmospheric extinction coefficient, visibility and illuminance from 5 m up to 20 km using backscattering technology, in a compact 316L stainless steel housing. It is supplied in the UK by MetSensor UK.
- ✓ Measures extinction coefficient, visibility and illuminance
- ✓ Backscattering measurement principle, 5m-8km typical, up to 20km max
- ✓ 2-channel relay outputs for alarm/control integration
- ✓ 316L stainless steel housing, compact 110 x 110 x 110 mm
- ✓ Low power: <2W normal, <20W with heating
- ✓ RS485, RS232, WiFi, Bluetooth, LTE interfaces

Frequently asked questions
What does the ZFD measure?+
Atmospheric extinction coefficient, visibility and illuminance, using backscattering of an infrared beam.
What relay outputs does the ZFD provide?+
Two channels of relay output, which can trigger alarms or control systems directly when visibility drops below a threshold.
What housing material does the ZFD use?+
316L stainless steel, suited to marine and offshore environments.
What is the ZFD's maximum detection range?+
Typically 5 m to 8 km, with a maximum capability of 20 km.
