Pneumatic Positioners-Series 150N
Low Cost, Field Selectabe Cam Design
W.E. Anderson Series 150N Pneumatic Positioners deliver stable process control at an exceptionally low price. This versatile unit is cam characterized which allows use of a single internal range spring for all control spans. Rotation of the cam allows split range applications to be easily selected. Its rugged, durable design makes it ideal for use in harsh environments while maintaining precise, accurate positioning of the control element. This multi-faceted positioner requires no additional parts to convert from direct to reverse acting. Readily accessible zero and span adjustments are conveniently located behind a removable housing cover.

EXAMPLE: For a 3-15 PSI Control System utilizing a Hi-Flow™ Valve with LIN-E-AIRE® Actuator Model No. 2004VA32-223-A*, order Model No. 150NL11-223.
*Suffix -A is added to Hi-Flow™ Valve Model No. if Pneumatic Positioner is to be factory mounted and calibrated.
APPLICATIONS
This low-cost alternative to the Precisorâ Pneumatic Positioner provides excellent modulating control when used between the Dwyer Temperature Controllers (models 1600 or 2500), Current to Pressure Transducer (Model 2200 and the Hi-Flow™ Valve in such industries as the food and beverage processing, chemical, pharmaceutical, and wood pulp and paper.
