OMC-506 Barometric pressure sensor
OMC-506 Barometric
pressure sensor
The OMC-506 Barometric pressure sensor is a high precision sensor with which Observator can guarantee an accuracy of ± 0.2 hPa. This sensor is often used within Met
systems on board offshore platforms, within the Obsermet
OMC-410 MultiMetProbe and various other applications.
The OMC-506 is based on a stable, floating piezoresisitive
transducer and a micro-processor with build in 16 bit D/A
converter. Output RS485 and an industry standard 4..20
mA signal
• High accuracy 0.03% FS
• Temperature compensated
● Range 800..1100 hPa (on request 600..1100 hPa)
● RS485 output and 4..20 mA output
● Low power consumption
● Fast response
● Excellent Long term stability
Barometric pressure sensor in OMC-183 housing
The OMC-506 Barometric pressure sensor is depended
on the configuration mounted into a cabinet together
with the signal conditioning unit OMC-183, mounted into
the housing of the MultiMetProbe or in a separate housing. In all situations there is the possibility to ventilate to
the outside air with a process connection.
Operating range 800 to 1100 hPa
On request other ranges available
