Description
Data logger PL315 is a high –performance and cost-efficient product
developed by our company. By using of the best low consumption
integrated chip and taking advantage of digital technology, PL315
is designed to record water depth (pressure) over long term. It
could be widely used in petroleum. Chemi-industry, power station,
water conservancy, city flood control and city water supply etc.
PL315 is a battery powered instrument, and work without manual
control. By setting proper interval recording time, one class AA
battery 3.6/2400mAh is possible to support the PL315 working many
years.
PL315 works with an absolute pressure sensor. If the influence of
air pressure fluctuations (e.g. at shallow fluid or water depths)
is going to be taken into consideration, it is recommended that a
second data logger PL315 is placed at the surface, to record the
barometric pressure. The correct level is calculated via PC by
subtracting the two measured values of the two data loggers.
Sensor, circuit board and battery air assembled into the sealed
steel housing, for submersible application. For data read out,
PL315 must be got back from the measuring point. The O-ring sealed
end cap is then removed to the access to data port.
