Description
PL350 intelligent wireless pressure transmitter is a low-power,
with intelligent wireless communications instruments, advanced
industrial-grade MCU as the core, high-quality sensor for the
collection front-end,
combined with industrial-grade wireless GPRS data module, the use
of China Mobile's mature GPRS network, to achieve the field
instrument data to the cloud wireless transmission. The instrument
reports the data according to the set interval, customers through
the Web page to achieve remote instrument configuration and data
access, upload and distribution of data are stored in the database,
to facilitate the latter part of the query.Through the Internet PC
or mobile terminal to access the relevant Web site to obtain
instrument data and to achieve the collection of data statistics,
analysis, form report and data curves, with intuitive, accurate and
efficient features.
