3.2 Intended use
The intrinsically safe process transmitter measures gauge pressure, absolute pressure
and vacuum. The physical quantity pressure is converted into an electrical signal.
Only use the intrinsically safe process transmitter in applications that lie within its techni-
cal performance limits (e.g. max. ambient temperature, material compatibility, ignition
protection type, ...). Instruments with a flush process connection must not be used with
media which might damage the diaphragm of the process connection.
→ Performance limits see chapter 15 “Specifications”.
