Siphons according to DIN 16282 are cooling zones for protection of

the pressure transmitters against too hot process media. A diﬀerence

is made between siphons in U or circular form.

Valves are used as shut-oﬀ device when connecting pressure

transmitters to the process. A diﬀerence is made between single or

double valves. Dependent on the version, the valves have a ventilation

option or a test connection.

Valves are used as shut-oﬀ device when connecting diﬀerential

pressure transmitters to the process as well as for pressure

equalisation of the measuring chambers during setup.

There are diﬀerent types of valve blocks: 3-fold valve blocks and 5-fold

valve blocks as well as valve blocks that can be ﬂanged on both sides

and those that cannot be ﬂanged. Ventilation valves enable ventilation

of the measuring chambers of diﬀerential pressure transmitters.

Oval ﬂange adapters according to IEC 61518 enable the connection of

pipelines with ½ NPT to diﬀerential pressure transmitters.

Measuring instrument holders enable wall or tube mounting of

pressure transmitters and suspension pressure transmitters.

Mounting brackets enable wall or tube mounting of diﬀerential

pressure transmitters, also in conjunction with a valve block.
