Pressure sensor measure?

Hi,

Help!! Please tell me, how can I measure pressure with DT800. We have the sensor model 3277: http://www.tecsis.de/filestore.aspx/de700.pdf?pool=website&type=file&id=833ae8a0-7d35-45c8-899b-11641fc94082&lang=en&filetype=default

With best greets,

Connection depends on if you have the 4-20mA Current output version of the Voltage output version. For the Current output the connection is Fig 105 on page 170 of the DT800 manual UM0068A2. For the Voltage output version it would be similar to Fig 100 on page 168.

The programming requires you set up a Span to convert the raw measurement from volts/mA to Pressure in your desired engineering units. You then setup the volts/mA measurement and apply the span.

In code this can look something like:

BEGIN"PRESSURE"
'Declare Span
S1=0,25,4,20"bar"
'schedule definition
RA1S
1I(S1,"Pressure")
END
