Passive Wireless Three-Way Temperature Measurement Sensor

Product Overview

The KL-DS33WB passive three-channel wireless temperature sensor is a high-precision three-channel temperature sensor featuring wireless transmission, ultra-low power consumption, and inductive power generation. It consists of three temperature sensors, a signal modulation and amplification device, a logic control circuit, a wireless communication circuit, and an antenna. This temperature sensor utilizes CT inductive power generation technology, making it universally applicable in temperature measurement scenarios with suitable electrical nodes. It requires no external power supply or battery power, offering significant advantages in product stability and ease of installation compared to externally powered temperature sensors which are difficult to deploy, and battery-powered temperature sensors which are susceptible to the impact of ambient temperature on their lifespan.

This temperature sensor is an upgraded version of the single-channel passive wireless temperature sensor product, expanding from the ability to collect temperature data from only a single node to the ability for a single sensor to simultaneously collect temperature data from three nodes. While maintaining the same performance, it saves customers costs, and market feedback has been positive. Its cost advantage is particularly significant in scenarios involving large-scale deployment of electrical node temperature monitoring.

This temperature sensor employs ultra-low power wireless communication to transmit the collected three temperature data points to a wireless temperature measurement host via a wireless network. The product is primarily used in low-voltage switchgear and similar applications.
