PID - Dwyer
PID controllers keep temperature, pressure, flow and level steady by continuously comparing the measured value with set point and adjusting the output. Proportional, integral and derivative actions work together for fast, stable control.
PID Controller Features
- Universal inputs – thermocouple, RTD, mA and voltage
- Relay, SSR and analog outputs – drive heaters, valves and drives
- Auto-tuning – fast setup
- Ramp and soak programs – multi-step profiles
- Communication – Modbus and Ethernet
Choosing a Controller
Select panel size, inputs, outputs and alarms based on your process. Heat/cool control and multi-loop options handle complex systems.
Centro supplies PID controllers for temperature and process control.
