8605型比例阀的电子控制设备 burkert

类型描述

数字的电子控制设备 8605，用于在功率范围 40-2000 mA 内控制电磁调节比例阀。电子设备会将一个外部标准信号转换成一个经过脉宽调制 (PWM) 的信号，利用该转换信号可以对比例阀开口尺寸进行无级调节，进而调节流体输出变量（例如流量）。一个将 PWM 信号占空比作为调节参数的内部电流调节装置，能够确保不管线圈的温度状态如何，都能为每个输入信号值明确分配一个有效线圈电流值。通过一个显示屏和操作按键，可以针对特定的比例阀以及具体的使用条件对电子设备进行轻易调整。

Type 8605 - Control electronics for solenoid control valves

Type Description

The digital control electronics, Type 8605, serves to operate proportional solenoid control valves in the power range from 40 - 2000 mA. The electronics converts an external standard signal into a pulse-width modulated (PWM) signal with which the opening of the proportional valve and hence a fluidic output parameter (e.g. flow rate) can be infinitely varied. An internal current control with the duty factor of the PWM signal as manipulated variable ensures that every value of the input signal, irrespective of the thermal condition of the coil, is unambiguously assigned a given value of the effective coil current. A display and operating keys allow the electronics to be easily adapted to a particular proportional valve and to the concrete conditions of an application.
