Samson Gets Even Smarter With New Valve Positioner

A new, high specification, yet competitively priced valve positioner has been introduced by SAMSON CONTROLS for use on their diaphragm operated valves. The Type 3725 Positioner is a logical development of Samson's proven range of Series 373x units and provides a compact and rugged, easy-to-use device.
Samson Gets Even Smarter With New Valve Positioner
In many of today's process control applications the preference is for 'smart', multi-function, digital positioners and it's often the case that the features in these devices remain redundant in use. In fact, a simple, self-calibrating positioner is ideal for less sophisticated control requirements and the 3725 unit has been developed for these situations. It is ideally suited for precise and reliable control of small or large flows occurring in food processing, pulp and paper or bottling plants.

The Type 3725 unit features the best of the proven Samson 3730-1 / 3760 positioners by combining the 'smart' features and LCD with an attractive, yet rugged black, UV-resistant polyphthalamide housing and transparent blue polycarbonate cover.

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 new 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. The 3725 positioner represents a smart, easy-to-use compact unit offering exceptional reliability at the most competitive price.
