Product Description

The 8326 pressure transmitter can be used in level control applications as well as for
pressure measurement applications in process industry. A variety of process connec-
tions, measurement ranges, main boards and display options result in a product for a
wide range of applications.
2.1

Construction

The 8326 consists of a pressure sensor, a control interface unit and a housing cover
with optional display. Due to this modular design, different transmitter versions can be
mounted.

2.1.1 Pressure Transducer

The pressure transducer has a piezo-resistive or thinfilm measurement cell depend-
ing on the pressure range. The sensors are temperature compensated, and have a
hermetically welded membrane which is "helium" leak-tested. The Pressure transduc-
ers do not have internal sealing elements.
Pressure transducers further distinguish themselves from one another based on their
pressure ranges and the different materials of wetted parts. Different process connec-
tions can be selected to serve a wide range of applications.
2.1.2 Processing Unit
The processing unit, which is integrated in the housing contains the terminal compart-
ment and the keypad used for programming the transmitter. The four keys must be
activated (unlocked) before use. During normal operation the keypad is locked to pro-
tect data and functions previously entered. The keypad is automatically locked when
no key is hit for 10 minutes. The processing unit converts the digitalized signal from
the measuring unit into a standard 4...20 mA current signal.
