پرشر سامسون مدل 3430 PRESSURE SAMSON

The controller directly measures the temperature of the process
medium, compares the measured value to the set point and
produces a pneumatic control signal of 0.2 to 1 bar (3 to
15 psi). The required supply pressure is 1.4 bar (20 psi) or an
operating air pressure of 2.0 to 12 bar (30 to 180 psi).
The controllers consist of a controller station, a controller module
with the required control mode and a transmitter module with
capillary sensor corresponding to the temperature set point.
Special features
– Controller and control valve form a unit to directly measure the temperature to be controlled which is easy to service and low in price
– Set point, controlled variable, system deviation and output
pressure are visible at a glance; all required adjusters and
switches can be operated on the front panel
– Can be equipped with modules for P, PI, PID or PD control
modes and additional modules for special control tasks
– Housing suitable for wall, pipe and panel mounting (front
frame 192 x 228 mm), optionally with lockable door of
transparent plastic (IP 65) with conductive coating
