Description

Non-intrusive level measurement systems are the preferred technology for many applications and for this reason SGM-LEKTRA developed the level/distance transmitters PTU51. These units are compact with a unique simplicity of commissioning. Calibration and transmitter configuration is possible, even remotely, thanks to a MODBUS RTU connection together with the related software for the PC, or via VLW90M / VLW60T display unit. The IP68 transmitter protection allows installation in underground wells. The application for configuration and programming via bluetooth, available on Google Play, is compatible with the most commen devices with operating system ANDROID 4.2 and subsequents. it is possible to read the measurements detected by the transmitter and set the configuration parameters of the sensor. The smartphone terminal must be equipped with the BLUETOOTH device of class 1 and version 2.1. The maximum reception / transmission distance is 15m in open air.
