2.7. Pressure Transmitter Installation

Pressure transmitters are available for the Optidew in several ranges. Any 4-20mA pressure
transmitter can be wired into the Optidew control unit via the 4-pin M12 connector. Michell
can supply a pressure transmitter with the Optidew, which is installed via a 1/8" NPT male
thread.
The pressure source should be installed with consideration to the calculated values which will
be used. For example, if the dew-point sensor is installed at process pressure, then the
pressure sensor should be installed into the sample block. However, if the if the dew-point
sensor is installed at a different pressure to the process, the pressure sensor should be
installed in a different location which is at full process pressure. For information on the
pressure compensation feature refer to section 4.4.5.
