THE CHALLENGE
According to the Union of Concerned Scientists,
“today’s on-road vehicles produce over a third of
the carbon monoxide and nitrogen oxides in our
atmosphere.” (03-Sep-2013)
The 1998 Consent Decree affecting all Heavy Duty
engine manufacturers in the US initiated the need for
Portable Emissions Measurement Systems (PEMS).
Since then, applications have substantially expanded
throughout the world, including:
In particular, heavy duty fleet in-use compliance
testing has spread from the US into Europe and Asia,
ensuring that vehicles continue to meet regulatory
standards.
Recently, the European Union promulgated EU6(c),
• Continued compliance and in-use conformity
which demands that all passenger cars be tested
testing against regulatory standards
under real world conditions as part of the certification
• Validation of powertrain and exhaust system design process.
• Development of air shed inventory models
• Determination of real world fuel economy
• Investigation of contributions of certain air toxins

EASE-OF-USE
The SEMTECH® LDV is designed for ease-ofuse and flexibility. Core modules consist of the
SEMTECH® GAS, measuring CO, CO2 , NO and
NO2, the SEMTECH® SCS, containing the Sample
Conditioning System, and the Exhaust Flowmeter,
EFM4.
The system may be mounted on a tow bar, with a
quick clamp to the vehicle, or in the vehicle trunk.
Externally mounted systems are sheltered with
an aerodynamic cover, which shields it from the
elements while minimizing drag on the vehicle.
Sample lines, pneumatics, and cables are
minimized with modules that mate directly via
electrical and pneumatic connections. Lines are
specially designed to allow the trunk to be closed
over them.
The system is controlled from the SEMTECH®
ICM, In-vehicle Control Module, which doubles
as a driver aid and in-vehicle communications
platform. The ICM features an easily accessible
E-Stop and event marker, and connects wirelessly
to a personal computing device for snapshot views
of system status, recording and route criteria

SAFETY
Safety is a primary design obligation. Sensors has
incorporated innovative solutions to mitigate all
known potential safety issues.

most extreme conditions.
Toxic Gases: Sample lines exhaust the sample gas
outside the vehicle, even if the system is installed
inside the vehicle. The use of flat heated lines enables
the trunk or hatch to be closed during operation,
minimizing the risk of exhaust vapors seeping into the
vehicle cab during on-road testing.
Heated Surfaces: All potentially heated surfaces, such
as the EFM4 tube assembly, include heat shields to
protect from accidental contact with any hot surface.
6
Electronics: All power lines used are 12 VDC. Power
cables have been replaced by Power-Over-Ethernet
where possible, to power up ancillary modules.
In-Vehicle Emergency Stop: The driver can cut power
to the entire system using the emergency stop of the
In-vehicle Control Module (ICM).

Heated Line: The heated line is a new, modular,
micro-processor controlled series of devices that
are low power, versatile and durable. Build custom
sample lines by connecting straight sections with
Flat-, T-, Y- and Right-angle- shaped connectors. Each
module is independently monitored and controlled.
Calibration: Connect the SEMTECH® LDV system to
shore power and to the SEMTECH® CAL 7-input gas
port calibration module to run automated calibration
procedures. The system can be programmed to run
the procedure at a set time, ensuring that the LDV is
ready for RDE testing when you are.
Host Software: The host software is an intuitive,
browser-based, multi-user interface designed for
routine PEMS operation with minimum of training.

SCALABLE ARCHITECTURE
Anticipating tomorrow’s needs, the platform
architecture is expandable, accommodating
additional analyzers, upgrades and other
accessories with ease.
SEMTECH® Dual FID
SEMTECH® CPN
Foreseeing all regulatory changes over the entire
life cycle of a PEMS analyzer can be challenging.
Opting for a non-scalable PEMS solution can prove
costly when new regulations require new analytical
capabilities only a few years into the life cycle of the
analyzer.
Adding a module to the LDV system is simply a matter
of plugging in another web appliance, or data node,
to the analyzers’ local network. Additional modules
may include:
• FID

the ECM supports. Adding a data point to the list
of points to be logged is as simple as checking a
checkbox!
Built into the ICM (In-Cab Control Module), the VCI
takes the guesswork out of interfacing to the vehicle.
Upon connection, the VCI will auto-detect the
vehicle’s protocol and baud rate. Then the VCI will
query the ECM to determine which data points are
supported.
The simplicity of this experience is also available
to our advanced users. When entering proprietary
data points or DMRs, the user is shown a live value,
allowing them to confirm proper setup and detect
configuration errors early.
These enhancements enable the smoothest user
experience possible. When creating the list of data
points to include in a test file, the user is presented
with live streaming values for all data points that
The VCI is quick too! It’s able to stream vehicle data
as soon as the ECM makes it available, allowing it
to perform as quickly as any other commerciallyavailable vehicle interface device.

ensuring reliable results.
Real-Time Data Processing: The new SEMTECH®
host software provides immediate access to
information critical to the completion of a successful
test sequence, including essential real-time hardware
diagnostics, to ensure that all conditions are met.
This critical real-time test information is available
