用於氣動自動化技術的創新型、支持 IO-Link 且免維護的差壓測量系統

隨著能源成本的增加,工業廠房中精確協調的流量和精確的消耗量測量正成為成本優化和能源效率的重要因素。憑藉 KDDM-2.2,Knocks Fluid-Technik GmbH 現在展示了他們用於壓縮空氣和中性氣體的免維護流量計的新版本,其特點是實用的精度、多種應用選項和良好的連接性。

 

用於運營成本控制、洩漏測量、監測空氣軸承或計量應用(例如噴漆機器人)的消耗測量只是自動化技術中的幾個例子,它們強調了精確流量測量的重要性。流量測量的常用方法使用量熱法或簡單的葉輪流量計。此類設備的問題一方面是對乾擾的敏感性高,另一方面是維護成本高。此外,經典的流量傳感器需要非常高純度的介質,它們還需要入口/鎮靜部分以減少湍流的負面影響。

 

KDDM-2.2 的開發除了對測量結果的高質量要求外,還特別旨在盡可能減少集成和維護工作。流動介質的質量對 KDDM 2.2 具有從屬作用。空間要求和對環境的要求降低到最低限度。由於其簡單而堅固的設計,KDDM-2.2 是工業環境中使用的理想儀器。

 

KDDM-2.2 使用響應時間短的差壓測量系統來確定流量、體積和壓力。該設備有一個入口壓力傳感器和兩個出口壓力傳感器。通過增加第二個出口壓力傳感器,可實現更高的測量質量和可測量範圍的擴展。傳感器之間有一個壓差孔。流量根據兩個測量點之間的壓差確定並顯示在顯示屏上。附加顯示選項反映壓力和體積。在高達 16 巴的壓力範圍內,可測量的流量範圍為 20 至 2000 升/分鐘。

 

通過添加“IO-Link”通信標準,在使用 IO-Link 軟件時簡化和加速了 KDDM-2.2 的集成和使用。尺寸為 102 × 63 × 83 mm 的緊湊型設備具有兩個可編程開關輸出和一個流量值模擬輸出。此外,KDDM-2.2 可以選擇通過 SIO 模式同時使用兩個輸出。可以使用按鈕或 IO-Link 快速簡單地配置設備。訪問代碼確保只有經過培訓的專家才能更改設置。

 

KDDM-2.2 可以集成到維護單元中,並可以在任何位置用作單個設備。具有 IP65 防護等級的設備與 Knocks Fluid-Technik 的模塊化 Futura 系列兼容。安裝不會限制下游設備的運行,因為在流量測量期間幾乎沒有壓降。該流量計還適用於運行過程中的部件監控,可以有效支持過程安全的各種措施。系統洩漏可以立即從變化的體積中識別出來,並且通過適當配置開關輸出會產生相應的警報或停機。

VOLUMETRIC FLOW METER KDDM 2.2

VOLUMETRIC FLOW METER KNOCKS KDDM-2.2

The innovative, IO-Link capable and maintenance-free differential pressure measurement system for pneumatic automation technology

Exactly coordinated flow rates and precise consumption measurements in industrial plants are becoming important factors for cost optimization and energy efficiency with increasing energy costs. With the KDDM-2.2, Knocks Fluid-Technik GmbH is now presenting the new version of their maintenance-free flow meter for compressed air and neutral gases, which is characterized by its practical precision, versatile application options and good connectivity.

 

Consumption measurements for operating cost control, leakage measurement, monitoring air bearings or dosing applications, such as for painting robots, are just a few examples in the automation technology that underlines the importance of precise flow measurements. Common methods for flow measurement use calorimetry or also simple impeller meters. The issue with such devices is on the one hand the high susceptibility to interference, on the other hand, the high maintenance costs. In addition, classic flow sensors, need a very high purity of medium, they also require inlet/calming sections in order to reduce the negative influence of turbulence.

 

The development of the KDDM-2.2 had in addition to the high quality demands on the measurement results the particular aim to reduce the integration and maintenance effort as far as possible. The quality of the flow medium has a subordinate role for the KDDM 2.2. Space requirements and demands on the environment are reduced to a minimum. Due to its simple and robust design, the KDDM-2.2 is the ideal instrument for use in industrial environments.

 

The KDDM-2.2 uses a differential pressure measuring system with short response times to determine flow, volume and pressure. The device has a sensor for the inlet pressure and two sensors for the outlet pressure. With the addition of the second sensor for the outlet pressure, a higher measurement quality and an extension of the measurable range is achieved. There is a differential pressure orifice between the sensors. The flow rate is determined on the basis of the pressure difference between the two measuring points and shown on the display. Additional display options reflect pressure and volume. The measurable flow range is 20 to 2000 l/min in a pressure range of up to 16 bar.

 

With addition of the "IO-Link" communication standard, the integration and use of the KDDM-2.2 is simplified and accelerated when using the IO-Link software. The compact device with the dimensions 102 × 63 × 83 mm has two programmable switching outputs and an analogue output for the flow value. In addition, the KDDM-2.2 has the option of using two outputs simultaneously via the SIO mode. The device can be configured quickly and simply using the buttons or IO-Link. An access code ensures that only trained specialists can change settings.


The KDDM-2.2 can be integrated into maintenance units and can be used as a single device in any position. The device with IP65 protection is compatible with the modular Futura series from Knocks Fluid-Technik. The installation does not restrict the operation of downstream devices, since there is practically no pressure drop during the flow measurement. The flow meter is also suitable for component monitoring during operation and can effectively support various measures for process security. System leaks are immediately recognizable from the changed volume and with the appropriate configuration of the switching outputs generate corresponding alarms or shutdowns.
