Sensor Des ription
The H6EX-A1 sensor is an Intrinsically Safe inclinometer that provides high accuracy, dual a is inclination over a
range of ±180° for Hazardous Locations. It is ATEX/IECE /MET (US)/CSA approved for use in Class 1, Division 1
and Zone 0 hazardous locations. The H6EX-A1 must be used with a certified isolation barrier.
This sensor incorporates MEMS accelerometers referenced to gravity with integrated temperature
compensation over the full operating range of -40° to +65°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 duple communication, along with a Rieker specific protocol. This
protocol can be used to measure the angle of both a es, as well as configure many of the parameters of the
sensor.
The H6EX-A1 provides two continuous, fully configurable, analog outputs. These outputs are individually
settable to current from 0mA to 24mA or voltage from 0V to 10V, are settable to either a is, and are factory or
user configurable to match any angle range and min/ma analog values.
Hazardous Lo ation Information
Intrinsically safe equipment is defined as “equipment which is incapable of releasing sufficient electrical or
thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmosphere
mixture in its most easily ignited concentration.”
The H6EX-A1 is ATEX / IECEx approved to:
E II 1G E ia IIC T4 Ga (-40°C≤T
amb
≤+65°C)
E ia IIC T4 Ga (-40°C≤T
amb
≤+65°C)
The H6EX-A1 is also US and Canada approved to:
Class I, Division 1, Groups A, B, C, D
Class I, Zone 0, AE ia IIC T4 Ga (-40°C≤T
amb
≤+65°C)
Certifi ate Numbers:
SEV 18 ATEX 0217
IECE SEV 18.0042
MET E114209
The H6EX-A1 sensor is intrinsically safe and suitable for all areas e cept mining (Group II / Class 1), can be
used in areas with continuous, long or frequent periods of e posure to hazardous gas (Zone 0 / Division 1), is
suitable for e plosive gas types Groups IIA to IIC and A to D, and has temperature group T4. It also has an
e tended operating temperature range of -40°C to +65°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.
