Mounting
Instructions
The following sections provide installation details for the various mounting
configurations. Refer to the following drawings for detector dimensions.
● 867468: 9719B scintillation detector, NEMA 4 housing
● 867469: 9720B scintillation detector, explosion proof housing
● 866778: 9701 ion chamber detector, NEMA 4 housing
● 866777: 9702 ion chamber detector, explosion proof housing
Warning Use proper lifting procedures during installation to avoid
injury. ▲
Caution Do not over tighten the bolts. ▲
For the dual chain mount, two mounting chains are wrapped around the
pipe with their ends engaging keyhole-shaped openings in the source head
mounting plate. The detector housing is then clamped to the two chains’
center links (opposite the source mounting plate) by tensioning bolt
assemblies.

Details of the chain mount depend on the detector type, but the
installation is similar for both types. Refer to the following drawings for
mounting details.
● 867466: 9719B scintillation detector
● 867467: 9720B scintillation detector
● 867172: 9701/9702 ion chamber detector
