LTr-3 is a smart Din-Rail signal converter for loadcell applications. Thans to its smal 6mm dimensions, it can fit all type of indsutrial applications. Stable and fast measuring fetures helps to adopt data from the sensor. Easy configuration via USB is also makes it faster setup. RS232/485 and Analog options can be chosen.
Updating device firmware can also be done via USB connectionile kolay parametre değiştirme, ayarlama ve kalibrasyon işlemleri yanısıra yazılım güncellemesi de yapılabilinir.
