Process Controllers

Process Controllers

A temperature controller plays a vital part in a multitude of processes. Along with a temperature controller there are controllers for pressure, pH, ORP, dissolved oxygen and pump control systems. You can get a temperature controller are available in benchtop (laboratory) models and panel mount (industrial) models. A temperature controller can accept thermocpules and RTD sensors and provide multiple output relays and alarms to provide a feedback loop for when the temperature goes outside of the desired range. Pressure controllers monitor your process pressure and provide output signals to keep the pressure at the needed range. For your water analysis and water quality control systems, Cole-Parmer offers a selection of pH, ORP and dissolved oxygen controllers. These controllers measure and monitor the parameters of water quality and provide output signals to other equipment to inject concentrations to keep the parameters at the needed ranges. Pump control systems are used in processes to help regulate the flow of necessary gases or fluids into a system. If you need help selecting the right temperature controller for your system contact a Cole-Parmer Technical Expert today.
