Operation
5.1 Introduction
The Series 907 Analog Convection Transducer is designed for applications which require pressure
control in the range of 10
+3
to 10
-3
Torr. Rapid response and wide measurement range provide the
equipment designer with maximum flexibility. The 907 Transducer can operate autonomously or as
part of a control system including that of a monitor or an alarm.
For process control, the 907 is available with one or two relay set points, each independently
adjustable with its own potentiometer. LEDs indicate the status of the set points.
