This
is a 48-96 DIN Temperature Controller, it is mains operated, it is in a
Industrial Plastic Housing. It is not meant for very harsh
environments. Suitable for Control Panels in Control Rooms. It has a
accuracy and linearity of 0.5%. It had options of on-off or time
proportional control
Temperature
is the most common process parameter, Pressure seems to be next. Flow,
Humidity, Strain, Torque, Level, RPM, Distance and many more follow.
When
a physical parameter let us say distance is measured, we first need a
sensor that converts it into electrical values, digital,
pulses(events/limit) or analog. The sensor used for length is a Linear
encoder and it creates the electrical information for the DRO to
Display.
