Pressure transmitters
measurement of static and dynamic pressures of liquids
and gases. The primary sensor is made of a piezoresistive
measurement bridge of polysilicon, placed on a monosilicon
shutter. A stainless steel membrane receives pressure
from outside and transmits it by means of an oil filling
to the monosilicon shutter. An electronic circuit turns
the signal of the measurement bridge into a 4-20 mA
signal proportional to pressure. The sensor absorbs
a pressure lower than 4 mA that allows the connection
with the transmitter in bifilar procedure. Said system
also allows checking eventual breaks in the line. The
pressure survey membrane is oppose type, rendering the
instrument not sensitive to impurities and offering
at the same time reduced overall dimensions. For uses
in places with high temperatures. The instrument is
equipped with the electronics placed far from the measurement
sensor. The connection between the two elements happens
by means of a ironclad, flexible pipe.
