Pirani Vacuum Sensor System
The Series 945 Pirani System, together with its Sensor and
connecting cable, provides accurate and reliable data for processes
which need pressure measurement from 10
+2 Torr down to 10 -4 Torr. It
is low in cost and easy to use.
The Pirani Sensor is available with one of several standard fittings for
vacuum connection. The Sensor connects to the Controller with a
cable that has a female octal socket on one end and a male, 9-pin D-
sub connector on the other. The Controller easily mounts into a ¼ DIN
panel cutout or stands alone. All controls, even the power switch, are
conveniently accessed from the front panel, and cable connections are
hidden to the rear of the Controller.
The Series 945 Pirani 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,
which 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.
