2 Introduction
2.1 P152 BASIC Overview
The P152 BASIC is a single point/basic functionality particulate monitor employing charge induction sensing for reliable
continuous monitoring of particulate in stacks, ducts, and pipes. Applications include filter leak detection, cyclone
overflow, and powder flow/no flow. The P152 BASIC is available in two versions.

Principle of Operation
As particles flow near or around the electrically
isolated sensing probe, minute charge is continuously
induced into the probe. The charge flows through a
measurement circuit to ground.
The induced charge signal is digitally analyzed and
processed to provide an output that is reasonably
linear to mass. The unit of measure is picoamperes
(pA). For highest accuracy and linearity to mass, refer
to model P150B/C.
For best understanding of particulate levels, 4-20 mA
analog outputs should be converted to pA at remote
recording devices or remote displays.

The following factors should be considered:
•Confirm compatibility of all sensor ratings with process and installation area.
•Check label for the following:
oWetted materials
oEnclosure rating
•Installation must be in grounded metal duct/pipe. Consult factory for non-metallic duct/pipe solutions.
•High levels of vibration should be avoided.
Filter Outlet Locations
①
Ensure good access.
②
Avoid locating within one pipe diameter or 36
inches of vertical stack exit to protect against
weather. Horizontal exits allow for closer
placement to open weather.
③Straight runs and laminar flow best for
measurement.
④Short straight runs are acceptable for basic leak
detection.
⑤Accessible negative pressure locations may be
preferred to prevent exposure to toxic gases
and particulate.

3.3 Sensor Mounting
Sensor Mounting Considerations
①
Process mount should protrude into process
0.125 in (3.175 mm) to 0.5 in (12.7 mm).
②Sensor probe should extend approximately
1/2 of the duct diameter for filter outlet
applications and 1/4 to 1/2 of the pipe
diameter for powder flow applications.
•In smaller pipes, the probe should be 1 in
(25.4 mm) minimum from the opposing side.
•High levels of vibration should be avoided.
Welding and Clearance
①
“Through weld” half coupling or quick-clamp
mount to ensure proper clearance and to prevent
particulate buildup in mount. Process
mount should protrude into process 0.125 in
(3.175 mm) to 0.5 in (12.7 mm).
②Do not face weld.
•Weld in center of the duct/pipe, perpendicular to
the flow.
•Air and watertight seal.

Improper Extensions
①
Do not use an extended or improper mount.
②
Longer mounts can cause the nipple not to
protrude into the process.
③Extended mounts can cause particulate
buildup on the insulator and sensing probe.
•Contact the factory for custom sensor nipple
extensions for proper installation in an
existing port.
•Do not use non-stainless steel mounts that
may corrode and cause corrosive residue to
drip on the sensor.
3.4 Test Port
Installation of a sensor test port is for introducing particulate upstream of the sensor as a method for checking the
response to an increase in particulate. Some applications are required by EPA regulations to include a sensor test port for
esponse Testing.
Location and Mounting
•Non-hazardous areas only.
•Negative pressure location.
•Install at least 3 ft upstream of the particulate
sensor.
•In line with sensor on the same side of the
duct.
•If possible, locate the test port at ground level
and/or a location with easy access.
•If the test port must be located at an
inaccessible location, a length of tubing can
be used to improve access.
•Typical test port is a 1/8” NPT x 3” long nipple
with a cap or shutoff valve.

prevent moisture from entering enclosure.
•The three plastic shipping thread protectors
must be removed and replaced during
installation to prevent water entry into the
housing.
ecommended Service Loop
•Flex conduit or instrument cabling and
ground cable should be sufficient length to
allow removal of the sensor.
•Recommended service loop is 1 to 2 times the

not required.
•P152E: Earth ground connection should be
made to one of the three ground locations:
oExternal enclosure ground screw.
oInternal enclosure ground screw.
oElectronics module earth ground
terminal.
•Analog wiring cable shield should be
terminated to earth ground in PLC/DCS
cabinet or at panel meter (terminate at one

•round wire should not impede service loop.
G OUNDING IN HAZA DOUS A EAS (MISE À LA TE E DANS LES ZONES

•For hazardous area applications, an external sensor earth ground cable is required to
maintain sensor grounding during installation and maintenance.
•The ground cable must remain attached when the sensor is temporarily removed
from the process. Do not disconnect the ground cable.
•Hazardous area installation of the P152D must be performed using drawing 56494
“P152A/D Intrinsically Safety Wiring”. The P152D unit must be marked for correct
hazardous area installation and required ratings.
•Pour les applications en zone dangereuse, un câble de mise à la terre du capteur
externe est nécessaire pour maintenir la mise à la terre du capteur pendant
l'installation et la maintenance.
•Le câble de masse doit rester attaché lorsque le capteur est temporairement retiré
du processus. Ne déconnectez pas le câble de masse.
•L'installation en zone dangereuse du P152D doit être effectuée à l'aide du dessin
56494 , « Câblage de sécurité intrinsèque P152A/D ». L'unité P152D doit être
