Introduction
MPM4710 Recording Transmitter is able to be widely used in petroleum, chemi-industry, power station, water conservancy, city flood control and city water supply and drainage, etc. It is supplied by battery, could work without manual control. The transmitter could record level or pressure change continuously. By setting proper data collection interval, the transmitter could record from several days to several years. Very low power consumption is another advantages, one AA baterry 3.6V/2400mAh could work many years continuously. MPM4710 has an absolute pressure sensor inside, to measure lower level, please be careful for atmosphere change. We suggest to install a barameter or another MPM4710 Recording Transmitter to record air pressure. And then calculate two pressure difference of two instruments by computer, that is the final level value; Please pay attention that get MPM4710 back from the measurement point, then remove end cap and read record through data interface.

-10℃~40℃ 0.10%FS(typ.) 0.2%FS(max.) -30℃~80℃ 0.15%FS(typ.) 0.3%FS(max.) ±1℃ 1s~255 hours 59 minutes 59 seconds (1s~10 days 15 hours 59 minutes 59 seconds) Recording stops when the records are 50,000 (including date, time, (no collection, no recording, no communication)<30uA Weight: about 500 g Resolution: 100MΩ/50V ①Error calculation: the absolute value of max. error at working temperature and pressure. Electric Connection
Chart 1 (the end side of transmitter) Pin 3 connects to GND of circuit inside. Generally, it can only connect to RS485A and RS485B. If RS485 communication has big disturbing, please connect to GND. Construction Outline

By software, users could calibrate transmitter zero, check battery, set data collection interval, read record and get temperature data and so on. Order Guide
MPM4710 (0~600)kPa R4 A the whole spec
Order Note
The basic transmitter measurement is absolute, please be careful that not to connect to power and cable when transmitter is not working. Please pay attention, if the atmosphere has big influence for measurement, please select a Pressure Recording Instrument, and use both two instruments together.
