Centering Ring with fine filter DN 16 ISO-KF 88396 Calibration service A calibration service is available for all Leybold gauges. Calibration is by comparison with reference gauges, traceable to National Standards. Contact Leybold for details. 300710168_002_C1 - 01/2018 - © Leybold... -
Page 9: Installation (Mechanical)
To connect the TTR91R to your vacuum system use an 'O' ring / centring-ring to connect a TTR91R with a DN16 ISO-KF flange to a similar flange on the vacuum system. To connect to a Leybold controller use a shielded cable which is terminated in suitable RJ45 connectors. These cables are available from Leybold (Cable Type A). -
Page 10: Recommended Electrical Connections
When using the TTR 91 R in an electrically noisy environment you should ensure that your measuring equipment is adequately immune to interference. All Leybold controllers have adequate immunity. The set-point output on pin 6 is an active low open-collector transistor suitable for driving a d.c. relay or control logic. -
Page 11: Operation
If the gauge is connected to a Leybold controller the display will indicate the measured pressure. The TTR 91 R provides a voltage output which is a function of pressure. The output voltage scales with 1.296V dc / decade. - Page 12 3.00E+00 6.757 5.00E+02 9.614 2.00E-02 3.958 4.00E+00 6.917 6.00E+02 9.716 3.00E-02 4.185 5.00E+00 7.042 7.00E+02 9.802 4.00E-02 4.345 6.00E+00 7.144 8.00E+02 9.876 5.00E-02 4.470 7.00E+00 7.230 9.00E+02 9.942 6.00E-02 4.572 8.00E+00 7.304 1.00E+03 10.000 300710168_002_C1 - 01/2018 - © Leybold...

Page 13: Gas Dependency
For pressures below 1 mbar a simple calibration factor can be used to correct for different gas types. Gas Calibration Factors (GCFs) for common gases are shown below. True pressure = GCF x indicated pressure Gas calibration factors below 1 mbar 300710168_002_C1 - 01/2018 - © Leybold... -
Page 14: Set-Point Adjustment
Note: If you use a Leybold Controller the TTR 91 R set-point is not used. To read the pressure at which the set-point output turns on, push the "S/P" button with an appropriate tool. The signal output of the gauge will change to indicate the set-point threshold for three seconds after which the output will return to normal. -

The tube of the TTR 91 R can be baked to 150°C, but the electronics housing must be removed. Referring to the figure in section 6.7, remove the electronics housing. When baking the tube on your system, do not exceed 150°C. Always allow the tube to cool before refitting the electronics housing. 300710168_002_C1 - 01/2018 - © Leybold... -

This may take several seconds. 3. Allow the gauge to operate at atmospheric pressure for at least 10 minutes and then repeat step 2. 4. It is now necessary to perform the vacuum adjustment as described above. 300710168_002_C1 - 01/2018 - © Leybold... -
Page 18: Replace The Gauge Tube
Whenever a new tube is fitted it is necessary to adjust the gauge to match the new tube. Refer to ‘Adjustment for new tube’ above. Replacement of gauge tube Electronic housing Retaining clip Gauge tube 300710168_002_C1 - 01/2018 - © Leybold... -

For the benefit of the environment, at the end of life of the transmitter, it should not be disposed in the normal unsorted waste stream. It should be deposited at an appropriate collection point or facility to enable recovery or recycling. 300710168_002_C1 - 01/2018 - © Leybold... -
Page 20: Declaration Of Contamination
All dispatch instructions laid down in the manual must be followed e.g.: • Drain all service fluids • Remove filter elements • Seal all openings airtight • Pack / handle appropriately • Attach the declaration of contamination outside of the packaging 300710168_002_C1 - 01/2018 - © Leybold... - Page 21 300710168_002_C1 - 01/2018 - © Leybold...
