The compact high temperature pressure

transmitter is designed for use in almost all

marine applications, and oﬀers a reliable

pressure measurement, even under harsh

environmental conditions.

The ﬂexible pressure transmitter programme

covers diﬀerent output signals, absolute or gauge

(relative) versions, measuring ranges from

0 – 1 to 0 – 600 bar and a wide range of pressure

and electrical connections.

A robust design, an exellent vibration stability,

and a high degree of EMC / EMI protection equip

the pressure transmitter to meet the most

stringent marine requirements.

Application

Cavitation, liquid hammer and pressure peaks

may occur in liquid ﬁlled hydraulic systems with

changes in ﬂow velocity, e.g. fast closing of a

valve or pump starts and stops.

The problem may occur on the inlet and outlet

side, even at rather low operating pressures.

Media condition

Clogging of the nozzle may occur in liquids

containing particles. Mounting the transmitter

in an upright position minimizes the risk of

clogging, because the ﬂow in the nozzle is

limited to the start-up period until the dead

volume behind the nozzle oriﬁce is ﬁlled.

The media viscosity has only little eﬀect on the

response time. Even at a viscosities up to

100 cSt, the response time will not exceed 4 ms.
