Pressure Transmitter for general applications

8323 • Piezoresistive or thin film sensor element
• Available with flush diaphragm standard
or acc. to EHEDG
• Housing and wetted parts in corrosion-
resistant stainless steel
• Standard signal 4-20 mA for connection
to automation-system

• Connector plug for fast installation and
service

The 8323 compact pressure transmitter is designed to cover the majority Envelope Dimensions [mm] (see datasheet for details)
of industrial applications in the field of industrial pressure measurement
technology. High accuracy, compact design, robust con-struction and
flexibility make this instrument universal and suitable for different meas-
urement functions. For technical reasons piezoresistive sensor element
is used for measuring ranges up to 16 bar and thin film sensor element
for the measuring range of 25 bar. Wetted parts are made of stainless
steel and completely welded. Internal seal elements, which could restrict
the choice of measuring materials, are excluded.
