These are the circuits and boards of a Mini Temperature Transmitter for a Platinum hundred ohms temperature Sensor.
Industrial Process Control Circuits
Analog Design in Process Control is seen at the Sensor Signal Conditioning Stage. Controllers also use Opamps for Analog Computation Tasks. These are Real Time in the Truest Sense.
A closed loop controller is the heart of an Industrial Automation System. Right from an On-Off Hysteresis Controller to a Auto Tune PID Controller, we find solutions of different complexities. Each solution might suit a particular system; depending on the requirements of Ease-of-use, Cost and Process Type.
Circuits in process control
- RTD PT100 Mains Powered Transmitter
- Blind Dial Analog Temperature Controller
- Mini RTD Pt-100 Three Wire Transmitter
Even today, the controllers at every stage of evolution, from the thermostat to Auto-Tune, are used in many countries, for many different industrial applications. No solution above is obsolete! The developing Countries still use electro-mechanical or semi-automatic means for control in some areas. and Process Type.
