SW4700-X
Wireless Passive Temperature Sensor
Category:
The SW4700-X series wireless passive temperature sensors are suitable for high and low voltage switchgear cabinets, monitoring the temperature of electrical nodes prone to heating. These sensors collect temperature data and transmit it wirelessly to prevent safety hazards caused by excessive contact resistance due to oxidation, loosening, dust, and other factors during operation. They enhance equipment safety, provide timely, continuous, and accurate reflection of equipment operating status, and reduce equipment failure rates. They can be widely used in industrial AI fields for temperature monitoring of busbars, star contacts, cables, and other components inside electrical distribution cabinets.

Design characteristics
· Self-powered, starting current <5A (433M), <3A (2.4G)
· Wireless transmission frequency 433M and 2.4G
· Temperature measurement range: -50℃~125℃
· Temperature measurement accuracy: ±1℃
· Low induction energy, high stability
· Operating power consumption ≤15W, enters standby mode with power consumption of only a few uW when the detected object is not operating
Product Advantages
· Intelligent transmission cycle: The sending cycle can be automatically adjusted based on the magnitude of the induced current on the contact arm or busbar.
· The passive wireless temperature sensor is small in size, easy to install, fixed with alloy sheets, and suitable for contact walls and busbars of various sizes.
· Flexible installation position, equipped with anti-slip silicone sleeves for easier and quicker installation.
· Shielded structural design with good anti-interference capability.
· The wireless temperature sensor uses special soft magnetic alloy material, generates very little heat, is unaffected by high current during temperature measurement, and has high accuracy.
