Series 947
CEP Vacuum Sensor System
The Series 947 Convection Enhanced Pirani (CEP) System, together
with its Sensor and connecting cable, provides accurate and reliable
data for processes which need pressure control from 10
+3 Torr to 10 -3
Torr. It is low in cost and is easy to use.
The CEP Sensor is available with one of several standard fittings for
vacuum connection. The Sensor connects to the Controller with a cable
that has 9-pin D-sub connectors on either end, one male and one
female. The Controller easily mounts into a ¼ DIN panel cutout or
stands alone. All controls, even the power switch, are conveniently
located on the front panel, and cable connections are hidden to the rear
of the Controller.
The Series 947 CEP
Controller is useful
either as a small
system controller
or as a module
in more
sophisticated
pressure control
environments.
The Controller
features two
standard relay set
points for process
applications.
The pressure readout
is a large, easy-to-
read digital display.
LEDs indicate the
status of relay set
points. Set points are
independently adjusted
using both a push-button and a potentiometer on the front panel.
The analog output and relay contacts are accessible from the
Accessory port on the rear panel.
The Sensor can be located away from the Controller using a cable as
long as 500 feet in length.
