Controllers & Timers

Dwyer controllers are designed to manage and regulate various process parameters such as temperature, pressure, flow, and level in industrial applications. These controllers are highly valued for their precision, reliability, and versatility, catering to a wide range of industries including HVAC, water treatment, and manufacturing.

Dwyer's temperature controllers are particularly popular, offering solutions for both simple and complex temperature control applications. They often include features like PID (Proportional, Integral, Derivative) control, which provides precise temperature regulation by continuously calculating an error value and adjusting the process control inputs accordingly. This is essential in processes where maintaining a consistent temperature is critical.

Tek-Trol 7900A-6H5 - Tek-Batch 7900A Batch Controller
Tek-Trol 7900A-6H5 - Tek-Batch 7900A Batch Controller
$2790.36 $3504.80
Tek-Trol 7900A-6H5 - The Tek-Batch 7900A is an analog input (4-20 mA, 0-5 V, 1-5 V, etc.) digital batch controller specifically designed for single and multi-stage batching applications. It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient SafeTouch® through-glass buttons for simple operation and menu navigation without having to remove the cover. The preclose deactivates a specific relay before the batch is finished in order to allow slower fill rates and increased accuracy. Automatic overrun correction keeps the batch size accurate over time and with system wear. The Tek-Batch 7900A includes a 24 VDC power supply to drive the flow meter and can be equipped with up to four internal relays and a 4-20 mA analog output.
