A Class I hazardous location is one in which flammable gases or vapors may be present in the air to be
ignitable or explosive. (Typical applications include petroleum refineries, spray finishing areas, utility
gas plants and fuel servicing areas.)
A Division 2 area is one where the flammable gases or vapors are normally not present in an explosive
concentration, but could accidentally exist.
Group A is Acetylene, Group B includes Hydrogen, Group C includes Ether and Group D includes
Hydrocarbons, fuels and solvents.
The Ultra SlimPak II is an exciting new line
of isolating signal conditioners from Action Instruments with greater accuracy
and better stability than virtually any other signal conditioners on the market
today. The Ultra SlimPak II features Smart Power, which eliminates wasted power
for low loop resistance loads in the current output mode.
The WV408 has both voltage and current input
ranges. Four voltage input ranges (±150mV, ±1.5V, ±15V and
±150V) are DIP switch selectable. Each of these ranges has at least 95%
zero and span adjustment, which, for example, would allow you to set a 0-20mV
user range on the ±150mV full scale range. Two current input ranges
(±2.5mA and ±25mA) are also DIP switch selectable. "Sigma- Delta"
conversion produces an effective resolution of 15 bits. Both voltage and
current have input accuracies of 0.015% of full scale. Outputs include 0-10V,
0-20mA and 4-20mA. The WV408 also supports reverse output. |
