I Safety Information

Explosive Gases

WARNING!
Do not use the Model 906A Convection Gauge Controller to measure
the pressure of combustible gas mixtures. The gauge normally operates
at low temperatures, but it is possible that momentary transients or
controller malfunction can raise the gauge above the ignition tempera­ture of combustible mixtures, which then might explode and cause
damage to equipment and injury to personnel.

Limitation on use of Compression Mounts

WARNING!
Do not use a compression mount (quick-connect) for attaching the
gauge tube to the vacuum system in applications that may develop pos­itive pressures. Positive pressures may cause the tube to be blown out
of a compression fitting and damage equipment and injure personnel.

Chemicals

WARNING!
Many organic cleaning solvents, such as acetone, produce fumes that

are toxic or flammable. Use such solvents only in areas that are well
ventilated to the outdoors and away from electronic equipment, open
flames, or other potential ignition sources.

III Overview

A. General Description

The Terranova Scientific Model 906A Convection Gauge Controller displays vacuum pressure as
measured from an HPS Model 317 Convection Enhanced Pirani (CEP) or Granville-Phillips

®

Model 275 CONVECTRON
conductivity of air/nitrogen or argon. The Model 906A controller covers the range from 0.1
mTorr to 1000 Torr or 0.1 µbar to 1000 mbar, and controls two relays with independent set points.

B. Specifications

1. Useful Measuring Range

0.1 mTorr (µbar) to 995 Torr (mbar), for air or nitrogen; (10-4 torr (mbar) to 103 torr (mbar));
range selection is automatic

gauge tube. It displays vacuum measurements based on thermal

2. Display Range

-19 mTorr (µbar) to 995 torr (mbar); pressures lower than -19 mTorr (µbar) display LO; pressures
higher than 995 torr (mbar) display HI; if cable is not plugged in display shows OFF

3. Accuracy of Interface to Gauge

Pressure calculation algorithm is accurate to ±1% of published data for the HPS Convection En-

®

hanced Pirani and the Granville-Phillips CONVECTRON

gauge (this is for the 906A controller

only, and does not include uncertainty of the gauge).

4. Units of Display

torr/mtorr or Bar/mBar; must be specified at time of ordering (see Section V-H for changing Units
of Display in the field)

5. Vacuum Gauge

HPS Convection Enhanced Pirani gauge, series 317 or Granville-Phillips CONVECTRON
gauge, series 275

6. Operating Temperature Range

®

+2 to +50 deg. Celsius

3-digit bright red LED, 10 mm high

8. Display Indicators

bright red LED for VAC, ATM, SET PT 1, SET PT 2

9. Display Resolution

varies; from 0.1 mTorr (µbar) below 10 mTorr (µbar), to 5 Torr (mbar) above 100 Torr (mbar)

10. VAC and ATM Adjust

adjusted by front panel push-button

11. Process Control Set Points

two, adjusted by front panel push-button

12. Process Control Relays

two relays, 2 amp, 240 VAC contacts; independent Normally Open and Normally Closed; +5 volts
is provided for TTL applications; available through the DB15 accessory connector

13. Nonvolatile Memory

for VAC, ATM and SET POINTS

14. Analog Output

calibrated, 12-bit resolution, logarithmic, 0.50 volts/decade; 0.0 mTorr (µbar) = 0 volts;
10 mTorr (µbar) = 0.50 volts; 100 mTorr (µbar)= 1.00 volts; etc.; available through the
DB15 accessory connector

15. RS-232 Input/Output

allows user to read pressure and set points; 9600 baud, 8-N-1; available through the DB15 acces­sory connector

A. Unpack the Controller

Carefully unpack the Model 906A Convection Gauge Controller.
The shipment includes these components:

• controller unit

• power cord

• mounting clips
DB15 accessory connector

•

• this instruction manual

IV Installation

If your contro

ller does not have all of these items, call Duniwa

y Stockroom. If it appears to have

been damaged in shipment, contact the shipper.

B. Mount the Controller

You can mount the controller unit freestanding on a bench, table top, or shelf, or you can mount
it in a rack or cabinet. The controller unit is housed in a standard 1/8 DIN box.

If you are mounting the unit in a panel, the cuto
ing clip attaches to each of the sides of the controller unit. To attach th

ut dimensions are 44 mm by 92 mm. One mount-

e clip, slide the beveled
surfaces of the clip under the cutout on the side of the box and push the clip toward the back of
the unit until the central tongue locks the clip in place. Then slide the unit into the panel; the clips
will hold the unit in place.

Be sure to leave enough clearance at the back of the controller unit for easy ac

cess to c

nections.

C. Select the Gauge Tube

The Model 906A controller is designed to work with the Granville-Phillips CONVECTRON

275 or HPS/MKS Enhanced Convection Pirani, series 317 tubes. If you have difficulty obtaining
a gauge, please contact us at Duniway Stockroom.
