mountings.
A 1/2 inch NPT female pipe thread is provided on the
mounting for attaching a swivel mount or sight pipe. Provision for purge
air is by means of a 1/4 inch female pipe thread on the side of the
mounting. A continuous flow of purge air is required for cooling.
A transparent Hirshmann connector with two LED's and 15 ft. length of
four conductor shielded cable is provided as standard is provided with
all viewing heads, except for the -PF model. The LED's assist in set-up
and self checking of the viewing head. Accommodation is provided for
