Caution

Caution

The Protec P3000 helium leak detector is supplied ready for operation. However, we
recommend that you carefully read the Technical Handbook to ensure optimum
operating conditions right from the start. This handbook contains important
information on functions, installation, start-up and operation of the Protec P3000.

If not stated otherwise this technical handbook applies to all three configurations of
the Protec P3000 (see Section 1.1.2). Sections specific to one configuration are
marked as "for … only". Sections marked as "for Protec P300 0XL only" always apply

1.1 Introduction

1.1.1 Intended Use

The Protec P3000 is a helium leak detector for sniffer applications. It may be used to
localise and quantify leaks in test samples if there is helium under an overpressure
within the test sample and when searching the test sample with a sniffer probe from
the outside (sniffer method). The use of this sniffer probe is mandatory for proper
operation and it is available as an accessory (Cat. No. 525-001 to 525-004).

HIGH FLOW mode).

The Protec P3000 must not be operated while standing in water or when exp osed
to drip water. The same applies to all other kinds of liquids.

This Protec P3000 should only be used in rooms.

Avoid contact of the Protec P3000 with bases, acids and solvents as well as
exposure to extreme climatic conditions.

Ensure sufficient air cooling (see also Section 1.1.2)

General Information 1-1

1.1.2 Available Configurations

The Protec P3000 leak detector is available in four different configurations:

The Standard Pr otec
P3000

The standard Protec P3000 should be used for high sensitivity applications. It
requires the SL3000 sniffer line.

The Protec P3000,
RC version

The Protec P3000, RC version is the standard Protec P3000 but with an external
display unit. It requires the SL3000 sniffer line.

The Protec P3000XL

The Protec P3000XL is the
leaks at a much higher distance from the potential leak at reduced sensitivity but can
be switched back to normal flow at inc reased sensitivity. In order to use both flow
modes (high and low) it requires the use of the SL 3000XL sniffer line. It may also be
operated with the normal SL3000 sniffer line, in this case the high flow mode is
disabled, however.

The Protec P3000XL,
RC version

The Protec P3000XL, RC version is identical to the Protec P3000XL, but with an
external display unit. It requires the SL3000XL sniffer line.

Service menu

Comprises the menu lines in the “Service” sub-menu. The service menu is accessed
by scrolling in the basic menu using the navigation push-b uttons (see also Section

3.2).

Autozero

Determination and compensation of the helium background. With this function, the
internal ZERO level of the leak rate signal is determined in order to avoid a readout
of the internal helium background and mistaking it as a properly measured value. If
subsequently negative leak rates are obtained due to this correction , the stored offset
values are changed so that ZERO will be the lowest value which can be obtained. In
this way the values adapt automatically to a decaying background (adaptive
background correction).

Internal background

The existing partial pressure in the measurement system. The level of the internal
background is measured all the time and subtracted from the measured signal.

I•Guide Mode

In the I•Guide Mode different testing plans can be pre-programmed. During testing
the operator is then constantly prompted for the next action and thus guid ed through
the testing plan.

Unit under test

Test object that needs to be leak checked.

Display limit

Limits the measurement data displayed depending on the unit of measurement and
the operator settings.

2 How the Protec P3000 Works

2.1 Description of the Functions

The Protec P3000 takes in helium through the SL3000 sniffer line, detects the
amount of helium by means of a helium sensitive sensor and converts the sensor
signal into quantitative leak rates.

The Protec P3000 is composed of the following principal subassemblies:

• A Wise Technology sensor as helium detector

• A valve holder for controlling different operating stati

• A diaphragm pump for pumping the gas to the sensor

• An inlet system for the gas flow

• The correspond ing electrical and electronic subassemblies for supplying power
and for signal conditioning.

The detector operates under gross vacuum conditions, i. e. the operating pressure
at the detector is several 100 mbar. T he under pressure is generated by a diaphragm
pump. The pressure in front of the sensor is measured with a piezo-resistant
pressure gauge and is about 250 mbar under normal operating conditions.

2.2 Description of the Subassemblies

2.2.1 Backing Pump

A diaphragm pump in the Protec P3000 serves as the backing pump. All data and
further information on this pump are given in the Operating Instructions. The backing
pump generates the flow of the gas through the SL3000 sniffer line.

2.2.2 Wise TechnologyTM Sensor

The helium detector (Wise TechnologyTM sensor) consists of a closed glass
container with a measurement device for the precise determination of the pressure
inside the glass housing and a mem brane chip wit h a large nu mber of small quartz
windows. The membrane is permeable only for helium, all other components of air
are retained by the membrane and from the inside of the glass housing. The Quartz
membrane is heated so that the permeation for helium is sufficiently high and fast.

Inside of the glass housing the total pressure is measured precisely. As only helium
can enter the glass housing the total pressure is equal to the partial pressure of
helium. The determined total pressure inside the housing is proportional to the
helium partial pressure outside the sensor.

2-1 How the Protec P3000 Works

kina26e Chapter 2.fm Technical Handbook(1209)

2.2.3 Valve Holder

The valve holder carries the valves that control the gas flow to the Wise Technology
sensor. These valves are used to select the sensitivity of the system, to activate a
protection mode against high helium contamination and to set the system into

STANDBY mode. The Protec P3000 software continuously analyses the situtation and

sets the correct valve position via the control unit.

2.2.4 Control Assembly

The control assembly (microprocessor) is the central assembly of the Protec P3000’s
electronics. All other subassemblies are controlled and monitored by this assembly.
The microprocessor which is located here is thus continuously informed about the
status of the entire Protec P3000 and can respond accordingly. In order to accept
commands from the operator and to output measured values and messages, the
control subassembly is linked to the display unit.

2.3 Description of the Displays and User
Interfaces

2.3.1 Main unit display

This subassembly is used to communicate with the operator. It accepts commands
from the 8 keys on both sides of the display and outputs measurement results and
messages via the display.
