Mfumo wa kupima joto usio na waya

Utangulizi wa vigezo na kazi za mfumo wa kipimo cha joto kisichotumia waya:
(Chini ni utangulizi wa kazi za sehemu ya kipimo cha joto kisichotumia waya. Tafadhali wasiliana nasi kwa maelezo ya kina.)

Ukusanyaji wa data na utendakazi wa maonyesho ya pointi za ufuatiliaji:

Kufuatilia kwa ufanisi hali ya joto ya kila hatua ya kuwasiliana wakati wa uendeshaji wa switchgear, kukusanya na kuonyesha data ya halijoto ya kila sehemu ya mawasiliano.

Mpangilio wa kizingiti na kengele ya kupita kikomo: Kizingiti cha joto cha hatua iliyopimwa inaweza kuweka. When the temperature measurement point exceeds the over limit value, an alarm indicator light will be output, and relevant contacts will be output. This can be used to connect the switch mode to the substation automation system, or to trigger other types of alarm alarms on site.

Data storage and upload: This host can store on-site data to the computer backend through RS485 communication for centralized display and management by the backend system.

Features of kipimo cha joto cha wireless kifaa:

Wireless transmission

Ensure complete electrical isolation between the temperature measurement point and the receiver to ensure electrical safety in high voltage environments.

Communication anti-collision technology

The unique wireless coding anti-collision mechanism greatly increases reliability during communication. Super strong power anti-interference ability, ultra-low power wireless transmission mode, saving 1.5-2 times more power than ordinary carrier coding methods.

Node maintenance free
The temperature sensor adopts advanced low-power and micro power consumption technology internally, ensuring a long battery life and reliable power supply during maintenance cycles.

man-machine interface
LCD display facilitates user data exchange.

Over temperature warning and alarm

Relevant warning and alarm thresholds can be set according to actual needs

Online real-time monitoring
Automatically monitor temperature changes at relevant key points online and upload the measured temperature data to the computer backend.

Easy to install and use

Kitengo cha sensor ya joto kina kiasi kidogo, ni rahisi kufunga, na ina ufanisi wa ufungaji wa haraka.
