SM46C Tension/Compression Sensor / Pull Sensor
Product Categories Tension pressure sensor
The SM46A series tension sensors are specifically designed for measuring various large-range static or dynamic tensile forces. Especially in harsh working environments where durability and technical reliability are paramount, this product can be designed according to general standards or customized to meet diverse application needs, such as various crane scales and overload protection devices. If the machinery has specific requirements for the tension sensor's shape or interface, our company can design and customize it accordingly. All SM46A series tension sensors are equipped with a standard current interface, CAN bus interface, or wireless sensor network interface.
