1.5 Correct use
The PT303 is designed for measuring pressure in explosive atmospheres (Class I,
Division 1, Groups A, B, C & D) as part of a larger overall system. It contains an
integrated signal amplifier. The PT303 pressure transmitter can be used in media
temperatures up to 170°F. If the pressure transmitter is used in other applications, the
safety and accident prevention regulations specific to that application must be
followed.
1.6 User’s obligations
The operator or owner of the larger overall system, e.g. a machine, is responsible for
