CAUTION
Erroneous pressure values
The transmitter may output erroneous pressure values.
Do not interfere or block the atmospheric reference port.
The low side pressure port on the inline gage transmitter is located in the neck of the
transmitter, behind the housing. The vent path is 360 degrees around the transmitter
between the housing and sensor (see
Keep the vent path free of any obstruction, such as paint, dust, and lubrication, by
mounting the transmitter so that the process can drain away.
