The
passive pressure transmitters in the HD 9408T series convert the pressure
variation exerted on a flexible Alumina diaphragm into a proportional and
linear 4 ÷ 20 mA signal on two wires.

The sensitive element is a bridge of piezoresistive
resistances laid on a diaphragm of special ceramic material. The bending of
the diaphragm leads to a variation in the resistances that is proportional
to and linear with the
pressure applied.
The quality of the materials and the technology used allow
the creation of elements that are very precise, reliable and repeatable over
time.
The
sensitive element is housed inside a container made of stainless steel AISI
303.
|
HD 9408T transmitters are made of stainless steel
cylinder, diameter 30x60, containing the pressure sensor and the
electronics; at the base there is a socket for a 24 mm spanner, while the
threaded part for connection top the pressurized system is 1/4" BSP.
On
the opposite side the transmitter is complete by a three-pole circular metal
connector in accordance with DIN 41524 and two muitirev trimmers with which
start and end of scale may be adjusted by about ±5% of their value.
