KDA Doppler Wedge Sensor

• Doppler (flow velocity)
• Piezo-resistive pressure measurement (level measurement)

1 MHz

IP 68

• ATEX: IBExU 07 ATEX 1082 Edition 1

-40 °C… +50 °C (also for use in Ex zone 1)

-40 °C… +70 °C

max. 4 bar (combi sensor with pressure cell max. 1 bar)

• 10 / 15 / 20 / 30 / 40 / 50 / 60 / 70 / 80 / 90 / 100 m; 
• pre-configured, can be extended upon request;
• a pressure compensation element is required if cables longer than 30 m are used with sensors featuring an integrated pressure measurement cell. The compensation element can be used also to connect the extension.

• Sensors without pressure measurement: LiYC11Y 2 x 1.5 + 1 x 2 x 0.34
• Combi sensor with pressure measurement:: LiYC11Y 2x1.5 + 1 x 2 x 0.34 + PA 1.5/2.5

• Sensors without pressure measurement: 8.4 mm ±0.25 mm
• Combi sensor with pressure measurement: 9.75 mm ±0.25 mm

“K” or “L” connector: for connection to the OCM F / OCM FR (OCM FR only in German-speaking countries)

• (Pipe/wedge) flow velocity sensor with v-measurement using the Doppler measurement principle and temperature measurement (to compensate for the effect of temperature on the speed of sound)
• Wedge combi sensor with v-measurement using the Doppler measurement principle;
  level measurement via pressure and temperature measurement (to compensate for the effect of temperature on the speed of sound)

for installation on the channel bottom
