SM46F pull sensor
Category:
Overview
SM46F Series The tension sensor is specifically designed for measuring a wide range of static or dynamic tensile forces. Especially on-site In harsh working environments where durability and technical reliability are highly demanding, this product can be designed according to general standards and non-standard customized designs to meet the needs of various applications, such as: various crane scales, crane overload protection devices, etc. If the machinery has special shape or interface requirements for the tension sensor, our company can design and customize it according to the requirements. The SM46A series tension sensors are equipped with standard current interfaces, CAN bus interfaces or wireless sensor network interfaces.
Features
Tensile measurement range from 1t to 25t optional; High reliability design; Multiple measurement signal output schemes: Analog standard signal output, digital bus output, Wireless sensor network output; Accuracy grade 0.3; The measuring body material uses high-performance alloy steel or stainless steel; The measuring body has a safety overload range of 200% F·S; Industrial design, protection level IP67; Operating temperature range from -40℃ to +85℃; ESD Electrostatic protection, EFT transient suppression; SPD surge protection; Power supply and signal reverse polarity protection; external steel connector protective cover.
