Your External PID Controller Died and the Pump Went to Full Speed
Pressure Controller with PID solutions for demanding industrial applications. The DR3601 series delivers reliable performance.
The Hidden Cost of External PID Controllers in Boiler Feedwater Systems
During a recent boiler feedwater project, we expected consistent pressure control from an external PID controller. Instead, we faced unexpected fluctuations that caused a 5% efficiency drop over three months—a $10,000 production loss. The culprit? Every additional device in the pressure control loop introduced latency and failure points. External controllers add milliseconds of response time and hours of maintenance, critical in environments where millisecond precision matters.
Why Electrical Noise Disrupts External Controllers
Our investigation revealed that fluctuations correlated with plant-wide electrical noise. External controllers lack the shielding and integration to handle interference effectively. This is where a digital pressure controller with built-in PID excels. By integrating PID directly, the DR3601 reduces component count from six to one, minimizing failure points and improving reliability. The result: a 2% efficiency gain within two weeks, saving $500 daily.
How Integrated PID Solves the Problem
The DR3601 is an intelligent pressure switch that processes control logic internally, eliminating signal degradation from long wiring and external noise. Its built-in PID functionality adjusts output in real-time, reducing jitter from ±5% to ±0.1%. This pressure controller with PID ensures stable readings even in noisy environments.
