DYNAINSTRUMENTS流量计DYNAguard S系列介绍

流量开关DYNAguard S用于监测柔性软管中的固体流量。当超过阈值时，它通过继电器输出指示。带模拟输出 (4…20 mA) 的版本可以额外指示流量趋势。

当（气动）运输颗粒、粉末、喷砂材料、磨料、灰尘或其他固体时，可以立即安全地识别储罐底部的堵塞、空料斗、鼠洞或产品桥。

测量原理基于检测移动电荷，这些电荷自然粘附在固体表面，例如通过软管壁上的摩擦产生。只有移动的粒子才会产生信号。

软管简单地穿过仪器（T 型）并用软管接头拧紧。在使用导电软管的应用中，或者在必须切割软管进行安装的情况下

，使用 E 型。此处软管从两侧插入软管接头。

柔性软管中散装固体的流量监测

• 积分测量和趋势输出

• 简单的流程整合

• 适用于导电和非导电软管

• 在气力输送和自由落体

The flow switch DYNAguard S is used to monitor the flow of solids in flexible hoses. It indicates through a relay output when a threshold is exceeded. The version with analogue output (4…20 mA) can additionally indicate a flow trend.

When granulates, powders, blasting material, abrasives, dust or other solids are (pneumatically) transported, blockages, an empty hopper, rat holing or a product-bridge at the bottom of a storage tank can immediately and securely be recognized.

The measurement principle is based on the detection of moving electrical charges which naturally adhere to the solids surface and are produced e.g. through friction on the hose-wall. Only moving particles generate a signal.

The hose is simply passed through the instrument (version T) and is tightened with the hose fittings. In applications with conductive hoses, or in cases where the

hose must be cut for installation, the version E is used. Here the hose is plugged into hose fittings from two sides.

Flow monitoring of bulk solids in flexible hoses

• Integral measurement and trend output

• Easy process integration

• For conductive and non-conductive hoses

• In pneumatic conveying and free fall
