Ultrasonic Integrated / EasyTREK® for Liquids



The newest generation EasyTREK SP-500 series level transmitters are based on NIVELCO’s 35 years of experience with
ultrasonic level measurement. The IP68 rated units have their transducer and processing electronics incorporated in
one single housing. The new EasyTREK transmitters utilize HART® 7 communication so they can be used in multidrop
systems connected to MultiCONT process controller/display, or to a PC with the help of the UNICOMM HART®-USB
modem or similar. The transmitters can be remotely programmed also with Handheld Field Communicator, and can
be connected wirelessly to a PC with the SAT-504 Bluetooth® HART® modem.
The members of the new EasyTREK SP-500 series can be recognised from the more compact size, the increased
maximum measuring range and the decreased minimum measuring range.
