PNEG-2175CE
CE Compliant Sampler - Model GCE 45 and GCE 90
Material Sample Transport Lines
The tubing used to transport material samples must be compatible with the operating environment and the
material sampled. Typically a 3.00" (75 mm) I.D. flexible hose is slipped over the discharge tube and held
in place by a worm clamp. The hose is then routed to allow material to flow via gravity to a convenient
collection point. At that point the hose may be connected to a collection jar bracket, a sample divider or a
sample collection system cabinet.
Rigid tubing may also be used if desired for the sample transport line.
Make all connections airtight and make sure all interior surfaces of joints are smooth and flush. Any ragged
or raised tube ends will collect dust and debris as well as retard material flow. Air leaks can interfere with
the pressure or vacuum conveying and sampling system. Escaping sample material can contaminate
surrounding atmosphere and equipment.
Controller Location
1. Use vibration isolation pads when mounting the control enclosure or mount the controller in a
vibration free location.
2. Locate controller so it is protected from water and dust.
3. DO NOT locate the controller in explosion risk area.
4. Most applications require that the sampler be in easy view of the controller.
5. Ideally controllers should be installed at ground level, inside or on a suitable work platform, making
controls readily accessible to the operator.
Field Wiring
The installer is responsible for the design, selection, protection and erection of field electrical wiring
between the sampler and its controls.
1. Conductor sizes shall be selected in accordance with IEC 60364-5-52.
2. Cable types and insulation shall be suitable for the anticipated installation environment.
3. The supply type shall be suitable for the installation:
a. Additional protective measures (ex: residual current device, residual current circuit breaker,
arc detection circuit breaker, over current and short circuit protection) shall be selected and
installed where the supply system requires or where the maximum fault loop impedance cannot
be guaranteed to provide automatic disconnection in the required time, in the event of an
electrical fault.
b. The prospective short circuit current shall not exceed that stated on the control rating plate.
