Sensor Description
The H6EX-A2 sensor is an Intrinsically Safe inclinometer that provides high accuracy, dual axis inclination over a
range of ±180° for Hazardous Locations. The H6EX-A2 must be used with a certified isolation barrier. It is
ATEX/IECEx/MET (US)/CSA approved for use in the following hazardous locations:
•Class I & II, Division 1
•Zone 0 & 20.
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 current and voltage analog
output options available. Each output is linear with respect to the input angle directly.
The H6EX-A2 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
configurable to match any angle range and min/max analog values.
Hazardous Location 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-A2 sensor is intrinsically safe and suitable for all areas except mining, can be used in areas with
continuous, long, or frequent periods of exposure to hazardous gas or dust, is suitable for explosive gas Groups
IIA to IIC and A to D and dust Groups IIIC & F to G, and has temperature group T4 for gas & T200°C for dust. It
also has an extended operating temperature range of -40°C to +85°C.
