Radar pulses 80GHz
IP67/IP68 (Sensor) – IP68 opt.
4÷20mA output
2 configurable relays
Remote control via Smartphone

Description

Compact unit for level measurement of liquids and solids RPL81 is unaffected by temperature fluctuations, high pressure and condensation. Thanks to his precise signal focusing it provides a reliable and accurate measurement. The RPL81 radar level transmitter can be easily configured by:
on-board push buttons (IP67 version only); VL620/621, “display/programming module”; MODBUS RTU s/w; BLUETOOTH + SGM Level APP.
4-20mA and MODBUS outputs enable the continuous transmission of the measurement to analogical and digital acquisition systems. Two configurable relays can be used as local alarm threshold and pumps drive/control. One relay can be programmed as operating alarm, making RPL81 suitable for unattended applications. Constructed entirely in PP, RPL81 is particularly indicated in presence of corrosive media (acid vapors) and therefore in storage tanks. Typical applications include water lifting and treatment plants as well as sea and rivers level monitoring.
