Installation
Guidelines
3. The transmitter should be mounted so that the display is easily seen
and the keypad on the transmitter (if applicable) is easily accessible.
4. The transmitter should not be mounted near high voltage, high
current, corrosive vapors, corrosive liquids, or corrosive esters.
5. There should be enough clearance to install and service the gauge head.
Refer to the appropriate drawings for your type of gauge and mount
(Appendix C).
6. The source housing should be positioned so that the radioactive source
identification tag is visible. The source housing tag should be upright.
7. The gauge should not be mounted where process overflow or other
material can collect in the beam path. The source shutter mechanism
must be kept free of debris.
8. The maximum cable length between the transmitter and the detector
varies with the gauge of the wire, but should not exceed 5000 feet
(1525 m) for an ion chamber detector or 1000 feet (300 m) for a
scintillation detector.
