DigitalTrak Compact Digital Valve Positioner
Features
The DT DigitalTrak is an intelligent electro-pneumatic positioner designed for precise valve control in automated systems. It operates on a 4-20 mA signal, comparing the setpoint with real-time valve position feedback to regulate air supply for accurate positioning. Built with microprocessor technology, it improves response speed and minimises control valve friction. The DT positioner features an autotuning system, integrated position transmitter, and a fail-in-place mechanism. Its compact, metallic housing ensures durability in harsh conditions, including sandstorm and copper-free environments. Suitable for single and double-acting actuators, the DT is widely used in oil and gas, power, and chemical industries.
