上海交通大学光纤技术研究所研制的QT型多功能逻辑报警控制器其基本功能是对探头线端的电阻电容变化给出逻辑开关控制信号。它既有远距离检测功能,又有远距离报警和控制功能。它借鉴计算机的“模块”设计思想,具有灵活的可扩充性和一定的逻辑性,可组成双液位逻辑报警控制器,三液位液源保护逻辑报警控制器、一机多探头防盗报警控制器等等。它的“滞后特性”适用于水库等液面波动
QT multi-function logic alarm controller developed by Institute of Optical Fiber Technology of Shanghai Jiao Tong University has the basic function of giving logical switch control signal to the change of resistance and capacitance of the probe end. It has both long-range detection capabilities, but also remote alarm and control functions. It draws on the computer’s “module” design philosophy, with flexible scalability and a certain logic, can be composed of two-level logic alarm controller, three liquid level protection logic alarm controller, a multi-probe burglar alarm control And so on. Its “hysteresis” is suitable for fluid level fluctuations in reservoirs
