visibility sensor model MV 110 pages

Standard Features 110 VAC, 230 VAC or 12VDCՕLow power consumptionDual alarm settingsՕUser configurable analog outputU-bolt mounting for easy installation Measurement principle Visibility is detected using widely accepted principles of forward scattering. A high output
infrared LED transmitter projects light into a sample
volume, and light scattered in a forward direction
is collected by the receiver. The light source is modulated to provide excellent rejection of
background noise and natural variations in
background light intensity. The sensorՒs analog
output signal is proportional to visibility. Visibility
is also compared to the preset alarm thresholds,
so that when alarm conditions are reached, the
outputs are switched. Visibility thresholds can be
set to any value within the instrument range.
Alarm outputs are toggled from 0 to 5 V, or from
5 to 0 V, when the alarm condition is satisfied. Mierij Meteo >

The Mierij Meteo MV 11 MV 11 Visibility Sensor is designed to monitor visibility conditions over a
range of 0-16 km. The includes bothanalog and digital outputs. Analog output ranges
of 0-1, 0-5 or 0-10 volts and 4-20 mA are available. Also included are alarm outputs,
which can be adjusted to alarm at user preset visibility thresholds. Two alarm channels are standard, making it possible to indicate Good/
Medium/Poor Visibility by setting the appropriate
thresholds. Digital RS232 and RS485 output at
300-38k4 Baud can be used to indicate the pre-
sent visibility and provide diagnostic information.High accuracy ՕProven optical technology Selectable alarm ՕCorrosion resistant Easy installation ՕLightweight design Easy installation and maintenance >
