Temperature monitoring system for factories and production workshops
Article Introduction:
Product details
1、 Purpose
Due to certain requirements for environmental temperature or internal temperature of equipment in some factories and production workshops, we hope to. Our company has developed and designed a temperature monitoring system for factories and production workshops that can monitor temperature in real-time. This system can monitor the environment within its workshopReal time temperature collection is carried out for equipment and cold storage, and the data is transmitted to a PC for data recording and analysis through software.
The influencing factors have been thoroughly investigated on site, and the main influencing factors are considered as follows:
1. The temperature inside the factory building is high, and there is a high requirement for waterproofing of the outer shell.
2. The temperature range for collection is relatively large, reaching -50 to 250 degrees Celsius;
The temperature monitoring system provided by Guangzhou Sibe Electronic Technology Co., Ltd. has environmental monitoring and alarm functions, and can be easily accessed through the network without any impact on the original system factory.
