TECHNICAL DATA FOR

POTENTIOMETER UNIT

SRI990 - Txxxx - H (for remote mounting)

This unit is made of a casing with inside only a heavy duty

potentiometer. This unit has to be connected to a SRI990

mounted separated on a more "safe" enviroment. Such kind

of remote mounting is specialy designed for high vibration

valves, high enviromental temperature, or high magnetic

field.

For more information see TI EVE0105 R
