Installation

ProcessPro transmitters are available in two styles: panel mount and field mount.  The panel mount is supplied with the necessary
hardware to install the transmitter.  This manual includes complete panel mounting instructions.
Field mounting requires one of two separate mounting kits.  The 3-8051 integral kit joins the sensor and instrument together into a
single package.  The 3-8050 Universal kit enables the transmitter to be installed virtually anywhere.
Detailed instructions for integral mounting or other field installation options are included with the 3-8051 Integral kit or the 3-8050
Universal kit.
