GPT247 Intelligent wireless pressure transmitter
GPT247 Intelligent wireless pressure transmitter is an intelligent instrument for pressure and liquid level detection with wireless communication function powered by high-energy lithium battery.
At present, multiple wireless communication modes are supported, including 433, LORA, LORAWAN, GPRS, LTE, NBIOT and WIFI. The man-machine interface adopts a 0.96 inch OLED screen with low power consumption.
It is suitable for the occasions where the field or supporting power supply environment is inconvenient, such as, monitoring the pressure and liquid level of pipelines of oil, gas, heating and water supply.
By means of wireless communication, the signal can be transmitted over a long distance, which simplifies the installation mode and saves the wiring cost, thus achieving the goal of energy saving and environmental protection.
