Compact sensor for 7 cables, rope diameter 8-13mm, 2 relays and analog current / voltage output Sensor for measuring cable elongation, with integrated evaluation unit. 2 relay outputs and analogue voltage or current output. All NG series systems have a USB input port for connecting an optional Wifi dongle. Via the wifi dongle the evaluation unit can be set with the free app and the documentation of the settings can be made. The documentation can be saved and sent. Requires an Android or I-Phone, tablet or I-pad or a PC. If necessary, the update of the firmware is also carried out via the USB input. When using the relays as full load and overload relays, a current of 4-20mA or a voltage of 0-10V is output linearly to load the sensors. The Holdeingang allows the interruption of the measurement while driving. This prevents unwanted overload measurements while driving. Furthermore, it is possible to compensate for weights of tie-chains and ropes when activating the Cade function. NOTE: The sensor clamp can also be used for 5 or 3 cables. Optionally, other terminals are available.
