2.1.4 Safety Precautions
The ST-H transducer body is a two part design molded in PVDF or ETFE with internal parts
potted in epoxy. The joint between the upper and lower sections is not a hermetic seal. The
structural integrity of the transducer will be compromised if the joint is exposed to an
environment that attacks epoxy. As a result, the top section will separate from the main body
of the transducer.
For environments that are compatible with PVDF or ETFE but may degrade epoxy, the
transducer must be mounted through a flange or stub mount using the 2" thread on the
lower section of the transducer. The joint between upper and lower sections of the
transducer must be isolated from the corrosive environment.
