Will: TSM - 01L type into type wireless liquid level transmitter is based on market demand and development of an integrated level and wireless data communication in the integration of high performance liquid level monitoring device, sensor technology, the low power consumption using high-energy lithium-ion batteries, the scene without external power supply can be directly collected liquid level signal, not only have data storage function, and have the function of automatic detection of real-time alarm, the process of liquid level signal of wireless remote monitoring is realized. Sampling interval, storage interval, reporting interval and other available software Settings. Nb-iot /GPRS/LoraWan and eMTC are available on a variety of networks. Application: The product is widely used in fire fighting, heating pipelines, water plants, oil refineries, oil pipelines, sewage treatment plants, urban gas pipelines and other industrial fields, to achieve the measurement of liquid, gas, steam pressure. Performance index: Input features Range: 0~5M (special range can be customized) Power supply: high-energy lithium battery (subject to the label of the instrument) Precision :0.2, 0.5 level Output characteristic Output signal: LCD field display, GPRS/ nb-iot /LoraWan wireless signal transmission (customized according to requirements) Long-term stability: + / - 0.5%FS/ year Transmission distance: there is no distance limit, and all areas covered by GPRS/ nb-iot network are available (LoraWan transmission requires gateway). Environmental conditions The temperature: - 20 ℃ ~ 70 ℃ Working humidity: < 90% Relative humidity: 0%~95% Protection level: table body: IP65, probe: IP68 Explosion-proof grade: ExdIIct6 Other data Display: segment display screen, 7 bit segment code dynamic display Process connection: M20*1.5mm Overload pressure: 1.5 times range Weight: 3 kg Operating current: dormancy <30uA, emission <350mA It can be used for 3-5 years under full power (according to the calculation of sending frequency of 10 minutes and 30 minutes, the battery needs to be replaced if the power is exhausted).
