Description
The oil fume online monitor is a oil fume online monitoring customer designed in response to the state's supervision of oil fume in the catering industry. The customer can continuously measure the concentration of oil fume, particulate matter, and non-methane total hydrocarbons (NMHC) in the kitchen exhaust duct for 24 hours, and upload it to the monitoring platform or government monitoring platform.
In order to prevent the purifier or the fan from non-operating, the customer can also collect two current signals through the current transformer to monitor whether the purifier or the fan is actually started.
For the operation of the solution installers, the whole machine adopts a 7-inch capacitive touch screen, and the full English interface setting is simple and easy to understand. The customer has a GPRS (optional 4G) communication interface, which can be inserted into a common mobile phone card or an IoT card for data uploading, and data can be uploaded where there is a mobile phone signal.
In view of the complex problem of oil fume components in oil fume monitoring, our company has designed a special sensor, which can accurately analyze oil fume concentration, non-methane total hydrocarbon concentration, and particulate matter concentration, and will not be affected by a large amount of steam generated by steamers and cages in the kitchen. impact, and monitoring is more accurate. With reasonable gas circuit design and advanced oil and gas separation device, it can achieve long-term maintenance-free operation, and can be maintained once every six months at most.
Features
Real-time monitoring of oil fume concentration, particulate matter concentration, and non-methane total hydrocarbon concentration, and can set the upper limit value, and automatically alarm when the limit is exceeded.
2-way current detection, can detect whether the fan and the purifier are working at the same time, can set the detection current alarm value according to the power of the fan and the purifier, adapt to all power fans and purifiers.
Using an open current transformer, it can be measured without cutting the fan or purifier cable.
Three independent working time periods can be set, and the alarm will be issued when the limit is exceeded within the time period, and no alarm will be issued outside the time period.
1-way GPRS (optional 4G) communication interface is provided with a 1-year IoT card, and the data can be directly uploaded to the free cloud platform provided by our company, the government oil fume monitoring platform or the customer's platform.
7 -inch capacitive touch screen is easy to operate. All English operation interface, beautiful and generous.
AC 220V power supply, IP65 protection level, can work outdoors all year round, not afraid of rain and sun.
Application
Residential community restaurant, specialty food street, school, unit canteen
