The Series 165 PRECISOR® II Pneumatic and Electro-Pneumatic Positioners
deliver stable process control at an exceptionally low price. Its rugged, durable design
makes it ideal for harsh environments while maintaining precise, accurate positioning
of the control element. Units can be easily changed from direct to reverse action,
or vice versa. Low air consumption keeps operating costs at a minimum, while still
responding quickly and accurately. Excellent for use in chemical processing, food and
beverage, pulp and paper, and pharmaceutical industries, as well as many others.
Positioners
BENEFITS/FEATURES
• Field selectable cam for direct or reverse acting
APPLICATIONS
Series 165 PRECISOR
excellent modulating control when used between the Dwyer Temperature Controllers,
Current to Pressure Transducer, and the Hi-Flow
and beverage processing, chemical, pharmaceutical, and wood pulp and paper.
HOW TO ORDER:
1. Select Model No. to specify input control signal.
2. For proper mounting hardware, order according to which actuator the positioner
will be mounted to.
