The LGS31, manufactured by NewSteo®, is an industrial wireless transmitter that transforms any potentiometric sensor into a wireless sensor that records the measurement or transmits it by radio to the supervision center. It comes with an LGS31, a potentiometric sensor input and LGP33 with three inputs. Furthermore, in the area which has to be monitored, the data loggers are spread out to sent the RF-to-USB though the radio frequency. It comes with a bridge in the RF to the Flash drive key that is in the PC and the loggers in between and an installed RF monitor into the PC that permits the loggers monitoring. In addition, it is a potentiometric assembly type with a 1KOhm to 65KOhm range measurements in an accuracy of 1LSB max meaning ±3x10-3% along with a 0,15s, maximum measurement speed and a 1s response time.
