PTU51

The non intrusive system application is still the favorite. The SGM-LEKTRA developed the PTU05.data processing unit to best exploit the its ultrasonic transmitter characteristics. The PTU05.unit offers, together with its compactness, a simple start-up. The PTU05. ransmitter calibration and configuration is possible, even remotely, through a MODBUS RTU connection together with their corresponding PC software or through the SWING display and power unit

· Contactless level measurements

· IP68 sensor mechanical protection

· PP sensor body

· Suitable liquids and granulates level measurement

· Integrated digital temperature sensor to compensate the flight time change

· Power Supply 24Vdc

· 4÷20mA analog output

· MODBUS RTU communication protocol
