About the Pulsarguard 201x series
General Description
Pulsarguard 2010 (green) and 2011 (blue, hazardous area approved)
The 201x series sensor uses state of the art soundwave technology to detect
change in structure borne acoustic emissions from equipment and materials
in motion.
The sensor listens to the high frequency sound generated by impacts,
cavitation and friction within a system.
100 to 600kHz is the bandwidth of the sensor making it immune to audible
noise or vibration caused by plant machinery.
Instant reaction to process variation provides a change in output level to
alert the user that an abnormal or different condition has been detected.

Chapter2 Installation
Sensor Positioning
Sensor Positioning
It is important that the sensor is sited correctly for each application. The sensor
must be installed near to where the acoustic energy is being generated.
The stainless steel housing has a tab with a 14mm hole through it, this is for
mounting the 201x, but it is also to hold the transducer in intimate contact with
the process being monitored. Good contact will maximise the voltage output.
To make the contact as good as possible try to fit on a flat clean surface, if
necessary remove any rust or paint prior to fitting. A couplant such as silicon
grease will also help to make a more reliable coupling.
If you are looking for particles in a liquid or solids travelling in a pipe then fit the
transducer near a bend on the side of the pipe where most impact will occur.
If you are listening to a bearing then fit near the bearing mount.
It may be necessary to experiment with the sensor position to obtain the best
results.
The mounting of the sensor is critical to operation, it must be tight, in the
right place and mounted on a clean rust and paint free surface, use of a
couplant such as silicon grease will help reliability.

Power Supply Requirements
The standard 2010 and HT version run on 24VDC and draw approx. 15mA. A
suitable DC supply will be required.
The 2011Z or G are a hazardous area product and certified to be used in Zone 0,
therefore it must be supplied via a suitable 28V safety barrier, either zener or
galvanic.
Wiring Detail
The 201x is supplied with a captive cable, 4m long, if other cable lengths are
required then specify when placing an order.
The 4 core cable is connected as follows for all PULSARguard

Instructions specific to hazardous area installations
Hazardous area version (blue)
(Reference European ATEX Directive 2014/34/EU, Annex II,
1.0.6.)
The following instructions apply to equipment covered by certificate number
Sira 04ATEX2121X:
1. The equipment may be used with flammable gases and vapours with
apparatus groups IIC, IIB, and IIA with temperature classes; T1, T2, T3,
T4 maximum ambient temperature range -20oC to +92oC, T5 maximum
ambient temperature range -20oC to +75oC, and T6 maximum ambient
temperature range -20oC to +40oC, and Group I maximum ambient
temperature -20oC to +92oC.
2. The equipment is only certified for use in ambient temperatures in the
range -20oC to +92oC and should not be used outside this range
3. Installation shall be carried out in accordance with the applicable code of
practice by suitably-trained personnel
4. Repair of this equipment shall be carried out in accordance with the
applicable code of practice.
5. Certification marking as detailed in drawing number D-804-0599-A.
6. If the equipment is likely to come into contact with aggressive
substances, then it is the responsibility of the user to take suitable
precautions that prevent it from being adversely affected, thus ensuring
that the type of protection is not compromised.
Aggressive Substances - e.g. acidic liquids or gases that may attack
metals or solvents that may affect polymeric materials.
Suitable Precautions - e.g. regular checks as part of routine
inspections or establishing from the material’s data sheet that it is
resistant to specific chemicals.

Page 12
7. The certificate number has an ‘X’ suffix that indicates that the following
special condition of certification applies;
When the equipment circuits are earthed (screen connected version,
Type ‘G’), it shall only be supplied from galvanic isolating barriers.
Because non-conductive plastic materials are used on the surface of the
equipment (i.e. the label is >4cm² in area), under certain extreme
circumstances, these non-metallic parts may generate an ignition capable
level of electrostatic charge. Therefore, when it is used in applications
that specifically require group II, category 1 equipment, the equipment
shall not be installed in a location where the external conditions are
conducive to the build-up of electrostatic charge on such surfaces.
Additionally, the equipment shall only be cleaned with a damp cloth.
8. The manufacturer should note that, on being put into service, the
equipment must be accompanied by a translation of the instructions in
the language or languages of the country in which the equipment is to be
used and by the instructions in the original language.
Identification:
The hazardous area versions 2011G and 2011Z are light blue and have
labels bearing the Certificate No. Sira 04ATEX2121X.
Another distinguishing feature is that the serial number on the tab of
the transducer is stamped with a suffix G (for use with galvanic
isolators) or Z (for use with Zener barriers).
