1 Scope
This European Standard specifies the safety, construction and performance requirements
for pressure sensing devices.
This European Standard covers type testing only.
It applies to pressure sensing devices for the measurement of pressures of combustible
gases of the first, second and third families, air, combustion products for maximum
inlet pressures up to 500 kPa (5 bar).
It applies to all types of pressure sensing devices, including electronic, differential
and inferential types.
It specifies requirements for pressure sensing devices which are intended to be applied
to steam boilers and as such need to meet increased reliability requirements. These
devices are classified as PSD-S in this European Standard.
