INFICON BPG400 ATM to Ultra-High Vacuum Gauge - Manual (Page 2)


Connect the sensor cable to the gauge.

Secure the cable connector with the lock screws.

Connect the sensor cable to the controller.
Operation
When the voltage is supplied, the measuring signal is avail-
able between pins 2 (+) and 12 (–) (Relationship Measuring
Signal – Pressure
→ "Technical Data" and  [1]).
BPG400-SD and -SP can also be operated via the corre-
sponding fieldbus interface (DeviceNet or Profibus
→  [1]
and [2] for further details and functions).
Allow for a stabilizing time of ≈10 minutes. Once the gauge
has been switched on, permanently leave it on irrespective of
the pressure.
Gas Type Dependence (BPG400)
The measurement value is gas dependent. The displayed
reading applies to dry air, O
2 , CO, and N 2 . For other gases, it
has to be converted ( → "Technical Data" and  [1]).
Adjusting the Gauge
The adjustment of BPG400-SD and -SP ( →  [1]
and [2]) is slightly different from the procedure for
BPG400, which is described below.
The gauge is factory calibrated. If used under different
climatic conditions, at extreme temperatures, through aging
or contamination and after exchanging the sensor, the char-
acteristic curve can be offset and readjustment can become
necessary. Only the Pirani element can be adjusted and only
at atmosphere.
Readjustment becomes necessary if
• at atmosphere the output voltage is <10 V or the display
reading is <atmosphere
• when venting the vacuum system, the output voltage
reaches 10 V before the measured pressure has reached
atmosphere (Gauges with display will show the error "5" at
atmosphere (Pirani sensor warning)).

Activate the gauge.
Operate the gauge for ≈10 minutes at atmos-
pheric pressure. If the gauge was operated
within the BA range, a cooling-down time of
≈30 minutes is to be expected (gauge tem-
perature = environmental temperature).

DANGER
DANGER: contaminated parts
Contaminated parts can be detrimental to health
and environment.
Before beginning to work, find out whether any
parts are contaminated. Adhere to the relevant
regulations and take the necessary precautions
when handling contaminated parts.
Caution
Caution: vacuum component
Dirt and damages impair the function of the vac-
uum component.
When handling vacuum components, take ap-
propriate measures to ensure cleanliness and
prevent damages.
Caution
Caution: dirt sensitive area
Touching the product or parts thereof with bare
hands increases the desorption rate.
Always wear clean, lint-free gloves and use
clean tools when working in this area.

Vent the vacuum system.

Put the gauge out off operation.

Unfasten the lock screws and unplug the sensor cable.
(If you are using BPG400-SD or -SP, unfasten and
unplug the interface cable too (
→  [1] and [2]).

Remove the gauge from the vacuum system.
Protective lid
Maintenance, Troubleshooting
In case of severe contamination or a malfunction, the sensor
can be replaced (
→  [1]).
Gauge failures due to contamination or wear and
tear, as well as expendable parts (e.g. filament), are
not covered by the warranty.
Returning the Product
WARNING
WARNING: forwarding contaminated products
Contaminated products (e.g. radioactive, toxic,
caustic or microbiological hazard) can be detri-
mental to health and environment.
Products returned to INFICON should preferably
be free of harmful substances. Adhere to the
forwarding regulations of all involved countries
and forwarding companies and enclose a duly
completed declaration of contamination
*) .
*) Form under www.inficon.com
Products that are not clearly declared as "free of harmful
substances" are decontaminated at the expense of the
customer.
Products not accompanied by a duly completed declaration of
contamination are returned to the sender at his own expense.
Disposal
DANGER
DANGER: contaminated parts
Contaminated parts can be detrimental to health
and environment.
Before beginning to work, find out whether any
parts are contaminated. Adhere to the relevant

when handling contaminated parts.
WARNING
WARNING: substances detrimental to the en-
vironment
Products or parts thereof (mechanical and elec-
tric components, operating fluids etc.) can be de-
trimental to the environment.
Dispose of such substances in accordance with
the relevant local regulations.
Separating the components
After disassembling the product, separate its components
according to the following criteria:
• Contaminated components
Contaminated components (radioactive, toxic, caustic, or
biological hazard etc.) must be decontaminated in accord-
ance with the relevant national regulations, separated
according to their materials, and recycled.
• Other components
Such components must be separated according to their
materials and recycled.
