ELECTRO-SENSORS速率计TR400系列产品介绍
TR400是一个全逻辑控制过程速率计，可以轻松和准确地显示任何生产速率或过程时间。准确检测和转换0.01至4,000Hz信号输入的能力使TR400成为许多工业应用的廉价解决方案。通过添加可选的继电器输出和/或4-20mA模拟输出，TR400成为一个完整的过程控制和显示系统。可选的继电器输出可以编程为低速或超速，并包括可调延迟在“通电”和输出激活。4-20mA输出可以缩放以反映监控范围的任何区域，包括需要反向输出的操作。
正交信号解码使TR400能够检测方向以及双向应用的速度。继电器和4-20mA输出可以反向和正向或双向编程。
The TR400 is a full logic control process ratemeter that can display any production rate or time in process easily and accurately. The ability to accurately detect and convert 0.01 to 4,000 Hz signal input makes the TR400 an inexpensive solution to many industrial applications. With the addition of optional relay outputs and/or 4-20 mA analog output, the TR400 becomes a complete process control and display system. The optional relay outputs can be programmed for under-speed or over-speed, and include adjustable delays at “power up” and output activation. The 4-20 mA output can be scaled to reflect any area of the monitored range, including operations requiring an inverse output.
Quadrature signal decoding gives the TR400 the ability to detect direction as well as speed for bidirectional applications. The relays and 4-20 mA outputs can be programmed in the reverse direction as well as the forward direction, or both directions.
