Introduction
The Terranova® 907 Dual Gauge Controller
is designed to simultaneously operate both a
Granville-Phillips 275 Convectron® gauge, MKS / HPS Series 317 convection-enhanced Pirani
gauge, or equivalent pressure gauge
and a
capacitance diaphragm gauge such as the MKS 722B
Baratron® capacitance manometer
.
The Terranova® 907 covers the pressure range between
1 x 10
-4
Torr to 1 x 10
4
Torr. The control unit can operate both standard and heated capacitance
diaphragm gauges with full scale ranges between 1 x 10
4
Torr and 2 x 10
-2
Torr that require a
± 15 V DC input and have a 0 V - 10 V DC output signal.
Installation
Mounting the Terranova® 907
The Terranova® 907 is housed in a standard 1/8 DIN box to allow for mounting on most
equipment racks or cabinets. The dashed call-out dimensions in
Figure 1
illustrate the proper
cutout dimensions for the 1/8 DIN box.
Figure 1.
Terranova® 907 cutout and unit dimensions
To properly mount the unit:
1.
Locate the mounting clips included with the control unit
2.
With the square end of the mounting clip facing towards the front panel, slide
the beveled surfaces of the clip under the cutout located on each side of the
control unit
3.
Push the clip toward the back of the unit until the central tongue locks the clip
4.
Tighten the rod against the rack or panel to secure the unit
If successful, the clips should hold the Terranova® 907 in place. Installation must not block vent
ports and should provide enough clearance to access rear cable connections.
