The Type 3725 unit features a UV-resistant polyphthalamide housing and transparent blue polycarbonate cover for protection in rugged conditions.

Data input and start-up is a simple process thanks to auto-tuning, while position sensing is contactless, performed using an AMR sensor. This method allows greater flexibility and enables the device to remain insensitive to vibrations, such as those generated by steam hammer. 

The 3725 positioner is designed to be used with Samson’s family of diaphragm operated valves, and can also be Namur rib mounted for travels up to 50mm as well as fitted to rotary actuators with VDI/VDE 3845 mounting.
