Ratings and Certifications
CSA certified for Division 1 & 2 hazardous area installations for explosion proof Class 1 Groups
B,C,D, and intrinsically safe (SenSmart 2000 2-wire loops only) Class 1 Groups A,B,C,D. Also
see sections 2.7, 2.7a & 2.8. Designed to meet CSA C22.2 No.152 for Combustibles Monitors
and ISA 92.0.01 Part 1 for Toxic Monitors.
2.2.1 SenSmart 3000 ATEX Certified Model
An ATEX certified SenSmart 3000 model (certificate # DNV-2007-OSL-ATEX-1845) is also
available by changing the SenSmart 3000 designation to ST-ATEX48. ATEX certified models
including sensors are supplied only with sensor head part # 10-2072 and are not available with
the 10-0247 sensor head or the 0010-
1200 “Y” fitting. ATEX installations must be in compliance
with EN60079-14 or suitable National or international standard and all cable glands and closing
devices must carry a suitable ATEX marking.
The ATEX label is shown below:

Sensor Location
Factors such as air movement, gas density in relation to air, emission sources and environmental
variables affect correct sensor location. Air movement by fans, prevailing winds and convection
should be carefully evaluated to determine if a leak is more likely to raise gas levels in certain
areas within the facility. Vapor density of a gas determines if it will rise or fall in air when there
are no significant currents. Lighter than air gases should have the monitors mounted 12
– 18
inches (30
– 45 centimeters) above the potential gas leak and heavier than air gases should be
this distance below. Even though the SenSmart 3000 is designed for rugged service, sensors
should be protected from environmental damage from water, snow, shock, vibration and dirt.
