pressure/differential-pressure
transmitters, incorporating its
DPharp digital resonant
sensing technology, includes a
version that is suited to the oil
and gas industry.
The low copper housing
DPharp EJA transmitter
features multi-sensing
capability, fast response time
and its compact design is said
to make the product range
significantly lighter than the
stainless steel versions
currently on the market.
Typically used to measure
liquid, gas and steam flow
rates as well as liquid levels in
tanks, pressure transmitters
are vital in maintaining safety
on an oil platform, triggering
safety shutdowns when
hazardous conditions are
detected. The new EJA series
offers new features and
benefits. For example, the
response time - the time from
the detection of a pressure
change to the change in the
output of an electric signal -
has been brought down to 90
ms, which equals the
capability of Yokogawa's
premium EJX series. This
faster response time will now
allow the new EJA
transmitters to be used in
high-speed applications such
as turbine surge control.
Secondly, the multi-sensing
capability means that a single
new EJA differential pressure
transmitter will be able to
measure both the liquid level
and the pressure in a tank, a
function that traditionally
could only be carried out
using two pressure
transmitters. This means it
can fit in installations where
space is limited and is also a
more cost-effective solution.
