Hazardous Area Considerations
The transmitter must be installed in hazardous area only if it is properly certied. The certication plate is permanently xed on the
side of the transmitter top housing (as shown by the gure).
The 266 Pressure Transmitter Line can have the following certications:
Transmitter
The transmitter can be anged directly to the shut-off valve. A mounting bracket for wall or pipe mounting (2" pipe) available as an
accessory.
Mount the transmitter in such a way that the process ange axes are vertical (horizontal in case of barrel-type aluminum housing) in
order to avoid zero shifts. If the transmitter is installed at an incline, the hydrostatic pressure of the lling uid would exert pressure
on the measuring diaphragm and thus cause a zero shift! A zero point correction would then be necessary. Pressure transmitters can
be mounted in any position.
Seal unconnected process connections on the sensor with the enclosed screw plugs (1/4-18 NPT). For this purpose, use your ofcially
approved sealing material.

Integral Display rotation
In case an optional integral display meter is installed, it is possible
to mount the display in four different positions rotated clockwise
or counterclockwise with 90° steps.

... INSTALLATION
Housing rotation
To improve eld access to the wiring or the readability of the optional
LCD meter, the electronic housing may be rotated through 360°.
A stop prevents the housing from being turned too far.
