overview：

LT10SR-4710 Recording Transmitter is widely used in petroleum, chemical industry, water conservancy, river survey, ocean, urban water supply etc. It's supplied by battery, which could work without manual control. This transmitter can record the changes of water level or pressure continuously, and it could record from several days to several years by setting collection interval. Ultra-low power consumption is its biggest feature. A 3.6V/2400mAh AA battery can work continuously for several years. LT10SR-4710 has an absolute pressure sensor inside, when measuring lower water level, the influence of atmospheric pressure change should be considered. It is recommended to install another LT10SR-4710 or barometer on the water surface to record the atmospheric pressure, and then calculate the pressure difference between the two measured values, that is the final level value. Please pay attention that get LT10SR-4710 back from the measurement point, then remove end cap and read records through data interface.

main features

● Using the latest microprocessor technology, pressure and temperature signals of the sensor have higher accuracy and resolution; digital compensation for both linearity and temperature error of the pressure sensor.

● Good data security due to NVM.

● Single 3.6V/2400mAh lithium cell for power supply, standby current ≤30uA, long-term collection available.

● Full stainless steel housing, multi-track O-ring sealing, battery replacement and data reading are convenient.

● Pressure, temperature, date and time when the recording occurred can be recorded completely.

● Flexible recording cycle, from min. 1s to max. 255h 59min 59s.

● Max.50000 complete records.

● RS485 protocol, freely wake up transmitter to set and read pressure value, temperature value and record operation.

● With factory recovery function, it can be recovered by software when the user makes a wrong setting, reducing cost.

● High-reliability design, Using multiple verification methods like hardware watchdog and software to reduce system crash.

● IP68 protection, long-term submersible application available.

● High-precision grade in a wide temperature range of -30℃~80℃.
