1. Description
ProcessPro transmitters are available in two styles: panel mount and
fi
eld 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 3-8052 integral kit joins 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
fi
eld installation options are included with the 3-8052 Integral kit or the 3-8050
Universal kit.
