測力佳測力佳載限制器是由傳感器、運算放大器、控制執行器和載荷指示計等部分組成,將顯示、控制和報警功能集于一身。當起重機起物品時,傳感器產生變形,把載荷重量轉化為電信號,經過運算放大,指示出載荷的數值。當載荷額定值的 90%時,發出預警信號;當載荷過額定載荷時,切斷起升機構的動力源。 通過對車的起升結構的取力(重量傳感器)反饋到該儀表中進行采集,對比,讀取,判斷后顯示當前重量并對其進行相應工況指示,過額定重量后快速切斷車鉤起升回路,使車不能起重物,從而保護車及操作人員的目的。 泛用于橋式類型起重機和升降機。有些臂架類型起重機(如塔式起重機、門座起重機)。
Measuringforce measuring force overload limiter is composed of a sensor, an operational amplifier, to control the actuator and load indicator components, display, control and alarm functions in a body. When the crane is lifting the goods, sensor generates deformation, the weight of the load into an electrical signal, through the operational amplifier, indicating a load numerical. When the load reaches 90% of its rated value, issued a warning signal; when the load exceeds the rated load, cut off the power source of hoisting mechani. The crane hoisting structure of the force ( weight sensor ) feedback to the instrument in acquisition, contrast, read, judge and display the current weight and its corresponding operating instructions, exceeding the rated weight quickly cut off the crane hook lift circuit, so that the crane cannot lifting heavy objects, so as to achieve the protection of crane and the operating personnel the purpose of safety. Pan used for the bridge te cranes and hoists. Some jib te crane ( such as tower crane, gantry crane ).
