Temperature Controller 48-96 - A 1/8 DIN Indicating Temperature Controller. This is a Analog Controller built around ICL7107. 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
J and K Thermocouple with 4-20 mA
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.
