Watson Smith P/I Converter 71 Type 712102

Watson Smith P/I Converter 71 Type 712102

The Type 71 P/I instruments convert pneumatic pressure into electrical signal. It is a two wire device, uses non- critical power supply and is supplied to IP65. With Hazardous Area approved to ATEX, its encapsulated electronics makes it good for shock/vibration performance.

• Hazardous Area Approved to ATEX

• Encapsulated electronics for good shock/vibration

performance

• A wide range of media compatibility

Watson Smith P/I Converter 71 Type 712102

Industry:

Paper converting, paper processing, wood

/ pulp processing, steel mills, plastics and

rubber manufacture, textile machinery,

wire handling.

Any industry requiring a reading of

pressure in a pneumatic system

converted to an electrical signal:-

• Dancer Arm Control

• Winder System

• Roller Tension System

• Roller Force Control

Solution:

Ensuring your application is operating at the right

pressure, the Type 71 measurers output pressure

and converts to a signal that can then be used to

offer application accuracy.
