Sensor Description
The H6EX-B sensor is an inclinometer that provides high accuracy, dual axis inclination over a range of ±180°
for Hazardous Locations. It is ATEX/IECEx & MET (US)/CSA approved for use in the following hazardous
locations:
•Class I & II, Division 2
•Zone 2 & 22.
The sensor incorporates MEMS accelerometers referenced to gravity with integrated temperature compensation
over the full operating range of -40° to +85°C for absolute accuracy. It has both digital (RS485) and analog
(current or voltage) output options available. Each output is linear with respect to the input angle directly.
The digital RS485 output uses two-wire, half duplex communication, along with a Rieker specific protocol. This
protocol can be used to measure the angle of both axes, as well as configure many of the parameters of the
sensor.
The H6EX-B provides two continuous, fully configurable, analog outputs. These outputs are individually settable
to current from 4mA to 20mA or voltage from 0V to 10V, are settable to any axis, and are factory or user
configurable to match any angle range and min/max analog values.
Hazardous Location Information
The H6EX-B is approved to:
US and Canada (Gas):
Class I, Division 2, Groups A, B, C, D T4
US and Canada (Dust):
Class II, Division 2, Groups F, G
Certificate Numbers:
ATEX/IECEx: SEV 18 ATEX 0217
IECEx SEV 18.0042
US/CAN: MET E114209
The H6EX-B sensor is suitable for all areas except mining where gas and dust are not likely to occur in normal
operation, but if so, will persist for a short period only. It is suitable for explosive gas Groups IIA to IIC & A to D
and dust IIIC & F to G, and has temperature group T4 for gas & T135°C for dust. It also has an extended
operating temperature range of -40°C to +85°C.
WARNING: If the equipment is used in a manner not specified by the manufacturer, the protection provided by
the equipment may be impaired.
AVERTISSEMENT: Si l’équipement est utilisé de façon non spécifiée par le fabricant, la protection assurée par
l’équipement peut être altérée.

Notes:
A. All grounding path connections should be secure, permanent, visible, and accessible. The grounding path
resistance from the farthest barrier to the grounding electrode should not exceed 1 ohm.
B. The installation must be in accordance with the National Electrical Code, NFPA 70, Articles 504 and 505,
Canadian Electrical Code C22.1 Section 18, and ANSI/ISA-RP12.06.01.
C. The H6EX-B Sensor’s Chassis Ground is NOT the same as the signal ground for the current output return.
The analog output return must be connected to the POWER/SIGNAL COMMON (pin 2).
Use
The sensor is designed to measure dual-axis inclination and output an analog and/or digital signal.
Assembling and Dismantling
The H6EX-B shall not be serviced, dismantled, or re-assembled by the user.

Installation and Mounting:
1. On the mounting plane, prepare surface with
three tapped holes, H1-H3 for M4/M4.5
mounting screws. H2& H3 are 3.815”
[96.9mm] from H1. See Figure 1. NOTE that
the single hole on the side with the two slots
is not meant to be used for mounting.
2. Mount inclinometer to mounting plane using
M4/M4.5 mounting screws. Use the two slots
for fine adjustments.
Default Horizontal Mount Option: Axis
Orientation
The 0° orientation for the horizontal-mount
option H6EX-B is a desktop, level position.
•For the X-axis, looking at the unit from
the side with the connector facing to
the right (top right of Figure 2), a
clockwise rotation from the zero
position is considered positive and a
counter-clockwise rotation from the
zero position is considered negative.
•For the Y-axis, looking at the unit from
the front with the connector facing
towards you (top left of Figure 2), a
clockwise rotation from the zero
position is considered positive and a
counter-clockwise rotation from the
zero position is considered negative.
Alternate Vertical Mount Option: Axis
Orientation
The 0° orientation for the vertical-mount option of the H6EX-B is a vertical position with the connector down.
•For the X-axis, looking at the unit from the top side with the connector facing down (bottom left of
Figure 2), a clockwise rotation from the zero position is considered positive and a counter-clockwise
rotation from the zero position is considered negative.
•For the Y-axis, looking at the unit from the side with the connector facing down and the mounting
surface to the left (bottom right of Figure 2), a clockwise rotation from the zero position is considered
positive and a counter-clockwise rotation from the zero position is considered negative.
