PIRECL Accessories, Duct Mount, and Sample Draw
The Model 375 HART Field Communicator is available from Detector Electronics Corporation
under agreement with Fisher-Rosemount Systems, Inc. The 375 Field Communicator enables
connection to the PIRECL via the onboard HART port connection.
In addition to standard replacement Weather Baffles, special replacement weather baffles for
PIRECL Eclipse are available including a version with a 1/16 inch FNPT, internally-threaded
calibration gas opening, enabling users to install a threaded compression fitting (not supplied) into
the baffle for use with plastic or metal tubing. Also available is a replacement weather baffle with
an external, 7/16-20 threaded calibration gas opening, used within the PIRECL sample draw cup
assembly p/n 007378-001. These special weather baffles are identical in all other respects to the
standard, factory-installed weather baffles provided on all standard PIRECL models.
The Remote HART Port Kit and Remote HART cable kit (Manual: 95-8553) are used with the
Model PIRECL PointWatch
®
Eclipse IR gas detector to provide access to the Eclipse's onboard,
intrinsically-safe HART port for a distance up to 20 meters. Cable set is 20 meter long, 2-core,
shielded 20 awg conductors with overall PVC-jacket, and is IEC332 approved.
The Direct Duct Mount Assembly (p/n 007525-XXX series) enables the model PIRECL
PointWatch
®
Eclipse sensing chamber to be installed directly within air handling ductwork. The
assembly is mounted on the duct wall, with the PIRECL sensing chamber exposed directly to duct
airflow, ensuring fast response to flammable hydrocarbon gases and vapors. A built-in calibration
gas nozzle with an external, self-sealing fitting enables testing and calibration without removal of
the detector from the duct. Not recommended for applications where duct air temperatures can
exceed 167 °F (75 °C). Price includes all necessary hardware for proper operation, but does not
include PIRECL PointWatch
®
Eclipse. A factory pre-assembled Direct Duct Mount Kit is available
(p/n 007529-XXX series) that provides a PIRECL PointWatch
®
Eclipse detector prefit into the
Direct Duct Mount kit assembly. Pricing for the 007529-XXX assembly includes the PIRECL
PointWatch
®
Eclipse.
The Model Q900 Duct Mount Kit is used with the PIRECL PointWatch
®
Eclipse to detect
combustible hydrocarbon gases within air handling ductwork. The Q900 is mounted to the exterior
of the duct wall and utilizes a duct inlet / return tube arrangement that provides cross-duct air
sampling without the need for vacuum pumps or aspirators. High temperature rated, flexible teflon
tubes are provided to enable easy access to optics for inspection purposes. Price includes all
necessary hardware for proper operation, but does not include PIRECL PointWatch
®
Eclipse
(except where noted). One duct air inlet tube and one return tube are furnished with each Q900 kit.
The Sample Draw Cup Assembly enables the Model PIRECL Eclipse to function within a gas
sampling system. It consists of an outer cup assembly with stainless-steel, inlet/outlet compression
fittings for 0.25 inch diameter tubing, a special inner baffle assembly with external-threaded
extension, and silicon gaskets to ensure proper cup assembly seal is provided.
