Product Description

WTZ - A300 loading-capacity limiter is used to monitor 2 ~ 4 channel weight, especially suitable for very large gantry crane, complex large lifting equipment. It can also be connected with a high external large size screen for the convenience of outdoor site construction personnel understand the current load of the lifting device in real time. When the load reaches the preset rated load, the limiter can release the audible and visual alarm signal, and output switching values.

Low power consumption, faster processing speed, higher accuracy, reliability, further improve; Applying optical coupling isolation circuit design, which has a strong anti-interference ability to solve the suddenly strong external interference influence on instrument when signal acquisition process. WTZ - A300 loading-capacity limiter interface shows not only the actual weight, but also the load rate percentage bar graph display. Menu form clear, very good for debugging and correction; Adopting civilian 220 vac and industrial 380 vac two specifications power input.
