- When the device is powered and the cover is open, protection against
electric shocks is not effective.
- Always ensure the materials in contact with the medium to measure
are chemically compatible.
- To clean the device, only use chemically compatible products.
- Do not insert any object (screwdriver for instance) inside the sensor
body. If the body is dirty, use compressed air to clean it.

The pressure transmitter 8311-2 wires is made up of an electronic mo-
dule and a measuring element. It may switch a solenoid valve, activate an
alarm or establish a control loop.
The adjustments can be carried out by means of the three keys located
under the display.
The transmitter housing can be turned by 180°.
The transmitter 8311 can be inserted in a fitting before being mounted on
any type of pipe.
The electrical connection is carried out via an EN175301-803 connector
and/or a steerable M12 multipin connector.
