August 5, 2025

E5AR Series Temperature Controller: Fast, Accurate & Customizable to Applications Specific Needs

The E5-R Series provides you with high-accuracy inputs (0.01°C for Pt100) and a 50ms sample and control cycle for all four loops. Its unique Disturbance Overshoot Reduction Adjustment ensures solid, robust control. The R-series can host multiple loops in one unit, The E5ER 2-loops and E5AR 4-loops maximum.

Applications

Mixing Two Flows: Ratio Control

• Used in applications where a secondary flow needs to be mixed in an exact ratio to the main flow, as in colouring paint, mixing yoghurt with jam and chloride with water.

Controlling a Processing Vessel

• In a fermentor, tight control over all the parameters such as temperature, pH, level and/or pressure is essential for a good product.

Temperature & Pressure Interaction in an Autoclave

• Sterilizing products at high temperatures under pressure demands a fast and accurate controller like the E5-R series.
