PPM-T9204 Explosion Proof Wireless Level Transmitter
Description
PPM-T9204 intelligent wireless liquid level transmitter is a high energy lithium battery powered, intelligent instrument for liquid level detection with wireless communication function. the instrument uses silicon piezoresistance with stainless steel isolation film as the pressure signal measuring element, pressure and temperature signals are collected by 24-bit high-precision ADC, the zero point and temperature performance compensation of the transmitter in a wide temperature range are realized. support a variety of wireless, 433,LORA,LORAWAN,GPRS,LTE,NB-IOT,WIFI etc. . the man-machine interface uses a 1.3-inch low-power LCD screen, operation display is convenient for application. the field of application is liquid level monitoring in the field or in the situation where the supporting power supply environment is inconvenient, such as fire tanks, pools, wells, etc. , by means of wireless communication, for long-distance wireless transmission of signals, this simplifies the installation, it saves the wiring cost of the customers, really achieve the goal of energy conservation and environmental protection.
