KWG100 Gas Monitoring Terminal
Product Details
The KWG100 (Manhole/Confined Space) gas monitoring terminal is an
advanced instrument produced by our company. It has the function of
wireless data upload and is used to monitor the gas concentration
in urban underground confined spaces. This terminal is designed by
adopting laser sensor and microcomputer technologies, combined with
excellent low-power consumption technology. It has the advantages
of power saving, intuitive display, good repeatability, long
service life, easy installation, simple maintenance, and convenient
operation.
This terminal is powered by batteries. It can use the existing
local cellular communication network to upload information such as
gas concentration, battery power, and the type of abnormality to
the data center via a wireless network either at regular intervals
or in the event of an alarm. Combined with the system software, it
can perform maintenance operations such as statistics, query, and
backup of the gas concentration information at each on-site
monitoring point.
This terminal is suitable for continuously monitoring and giving
early warnings of the gas concentration in urban underground
confined spaces such as gas valve wells, water supply and drainage
wells, power wells, and communication wells.
Product Advantages
- Adopts an advanced ultra-low-power consumption 16-bit
microcontroller.
- Battery-powered.
- Excellent low-power consumption design.
- Segment code liquid crystal display screen, with an intuitive and
clear display.
- Wireless data upload function, with a dual data upload mechanism of
time + event (alarm).
- Remote parameter configuration.
- Two-level alarm.
- Intrinsically safe equipment, which can be used in explosion-proof
areas.
- IP68 protection level, providing dustproof and waterproof
performance.
Main Applications
This terminal is suitable for continuously monitoring and giving
early warnings of the combustible gas concentration in urban
underground pipe networks such as gas valve wells, sewage wells,
power wells, water supply wells, and communication wells.
