Equipment Health
Monitoring (EHM)
Systems
Detectors
DESCRIPTION
Honeywell Equipment Health Monitoring (EHM) System
Detectors are designed to monitor equipment steady state
physical characteristics and provide the output to generate an
alarm when these characteristics deviate from pre-defined
settings. The fault may then be quickly investigated and the
problem corrected before it becomes so serious that a line is
shut down, production is lost and costs spiral.
The EHM’s output is expressed in two ways:
• The device’s dual color LED changes from normal green to
red.
• At the same time, the device's output changes state from
open to closed. This output may be connected to an alarm
or PLC input, allowing the alarm to be graphically shown
and to generate a "system" alarm.
Ten versions of the EHM are available for potential
applications requiring independent system monitoring of such
physical characteristics as temperature loss or rise, vibration,
fluid flow or leak, mechanical noise or wear, slope change,
mechanical insertion or audible noise.
Installation is simple. The EHM detectors are ready to be
attached directly to equipment and, after a quick calibration,
will begin monitoring for faults immediately.
A demonstration kit, as well as accessory/replacement
connector pins and cables are also available.
FEATURES
• Enhanced reliability designed to provide early warning fault
detection for protection of valuable equipment
• Visual and electrical alarm output is simple to integrate and
makes current equipment status easy to monitor
• Digital output means no time-consuming data collection and
analysis required
• Internal monitoring circuitry means no outside design
needed
• Easy installation and calibration provides quick set-up and
immediate use
POTENTIAL APPLICATIONS
• Wide variety of stationary and mobile equipment health
monitoring. See page two for specifics

HG1171 Series
6DF Inertial Measurement
Unit
DESCRIPTION
The HG1171 Series is a six degrees of freedom (6DF) inertial
measurement unit (IMU) that senses rotation rate about the
roll, pitch and yaw axes (X, Y and Z axes) and acceleration
along the longitudinal, lateral and vertical axes (X, Y and Z
axes, see Figure 1 on page 2). This product is designed for
enhanced accuracy of tracking and monitoring of
vehicle/platform (up/down, left/right, forward/backward) in a
hard mounted configuration.
KWP (Keyword Protocol) is used for self-test, health reporting,
software loading and related tasks. KWP 2000 (or ISO14230)
is a defined protocol for monitoring health and status of a unit
on a CAN bus (primary use is for off-vehicle test equipment). It
supports high speed IMU flashing for re-reprogramming.)
It provides key data for automated steering and vehicle
controls, freeing the operator to focus on machine functions,
one of the main reasons customers use IMUs.
A temperature sensor in each rotation rate sensor provides a
temperature value to the processing module where the
samples are filtered and compensated. This information allows
the customer’s system to perform over a wide temperature
range.
The HG1171 contains high performance MEMS (Micro
Electromechanical Systems) rotation rate sensors
(gyroscopes), whose function is based on the physical
properties of the Coriolis effect, as well as enhanced precision
integrated accelerometers for each axis.
Customization of I/O timing, CAN labels, connectors, and other
parameters allows the customer to specify changes in the IMU
so it more readily fits into existing architecture on vehicle.
The tough metal housing is often ideal for demanding
environments. The user may mount the product on the vehicle
frame outside the cabin, anywhere an IMU is needed.
High speed CAN bus (2.0 A or B) provides cost-effective, highintegrity serial data communications bus for real-time control
applications operating at data rates up to 1 Mbit/s. This
capability allows enhanced error detection and confinement.
FEATURES
• 3-dimensional rotation rate and acceleration outputs (roll,
pitch, yaw)
• High speed CAN bus
• Broad dynamic range
• Low noise
• High resolution
• Customizable
• Enhanced temperature performance
• Tough metal housing
POTENTIAL APPLICATIONS
Vehicle stability control systems on:
• Agricultural equipment such as tractors and harvesters to:
− Provide motion control feedback (attitude/accleration) for
leveling cutting blades, planters, tillers and other
equipment when on slopes or hills
− Improve automated steering capabilities by providing
rotational rate change data to vehicle controls
− Smooth GPS data (position and velocity) for use in high
accuracy planting/tilling
• Construction equipment such as excavators, trucks, forestry
equipment, loaders and graders to:
− Improve operator awareness relative to equipment loading
and extension envelopes on cranes and material/
telescopic handlers
− Provide real time stability control in rugged and steep
terrain
− Provide active depth and angle control for graders
− Provide motion compensation in GPS-guided automated
vehicles
