Introduction to Hydrosteel 7000TL
The Hydrosteel 7000 TL (Transportable light) is an instrument for the measurement of hydrogen flux from
pipes & vessels in Zone 2 hazardous areas.
The system is made of a number of sub components. It comprises of a Hydrosteel 7000 in a protective
housing, a timer operated battery box with mounting bracket, interconnection jumper cable, and safe area
battery charger. See layout drawing for a pictorial representation.
Note the Hydrosteel 7000 when powered with this battery in zone 2 area must be protected from impact by
the use of impact guards only removable by use of a tool or installation in a suitably rated enclosure. For
operation details of the Hydrosteel 7000 please refer to Hydrosteel 7000 instrument manual.
HY7K-TL battery
The Hydrosteel 7000 TL is powered from the timer operated battery box mounted locally. The battery box is
connected using a jumper cable to the Hydrosteel 7000. The timer inside the battery enclosure is used to
program the number of measurement cycles per day and switches on the Hydrosteel 7000 on and off as
required. There is an override switch on the outside of the battery (with Green indicator LED) to power the
Hydrosteel out side it’s normal timings to enable customer data download. Also included is a Red LED that
indicates when the battery power is low and requires charging.
Hydrosteel 7000
Hydrosteel 7000 operates a 10 minute measurement cycle. The unit draws a controlled flow of sample gas
from the probe into the unit, where the concentration of hydrogen gas in the sample is measured. At the
end of each cycle, all readings and diagnostic are logged to the internal memory. If the 4-20mA outputs are
powered they will provided output the latest reading at the end of each measurement cycle. See Hydrosteel
7000 manual for further information on its operation.
