The Smart Wireless Digital Temperature Transmitter is a high-precision, intelligent measurement and control instrument that integrates temperature measurement, data display, and wireless communication. It can be connected to the PT100 temperature sensor, and temperature compensation and multi-point calibration are performed for temperature drift, sensitivity, and nonlinearity to ensure the accuracy and stability of the measured data. The instrument is equipped with a segmented LCD screen and operation buttons to facilitate on-site personnel to master monitoring data; at the same time, LoRa, WiFi, NB, and 4G wireless communication networks are used to upload the collected data to the receiving host. The instrument is powered by a high-energy lithium-ion battery, and with a low-power sleep design, the battery life can reach more than 6 years.
