The instrument adopts silicon piezoresistive pressure sensor or strain gauge pressure sensor that with stainless steel isolation film as pressure signal measuring element and adopts 24-bit high-precision AD converter to collect pressure and temperature signals, realizing the zero-point and temperature performance compensation of wide temperature range for the transmitter. At present, multiple wireless communication modes are supported, including 433, LORA, LORAWAN, GPRS, LTE, NBIOT and WIFI. The man-machine interface adopts a 1.3 inch OLED display 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. ■ RANGE SELECTION t Pressure range Notice: For special requirements, please contact the manufacturer.
