Durchflussregler / Massendurchflussregler / Digital Mass Flow Controller

Basierend auf dem Azbil µF™Sensor bietet der MQV Massendurchflussregler für Gase schnellste Regelung und höchste Zuverlässigkeit auch bei geringem Differenzdruck. Für Regelbereiche von 5mL - 500L/min Description The MQV series of advanced digital mass flow controllers employs our proprietary thermal flow rate sensor as the sensing element, combined with a proportioning solenoid valve and advanced actuator technology. The result is a high-performance next-generation controller. Developed for general industrial use, the MQV series was designed with high-speed, wide rangeability flow control needs in mind. The MQV series uses µF sensor output and advanced PID control technology to drive a proportional actuator. Very low flow rate models of 5, 20, and 50 mL/min have been added to the line-up, expanding the available application ranges. Features ◾Achieves 300 ms high-speed control (700 ms for the MQV0050/0200/0500/1000J and K). The MQV series offers exceptionally fast response from no flow to the stable set point flow rate, and after set point changes. This high-speed response to changes in primary gas pressure can minimize the effects on secondary flow ◾Reliable control ◾The line-up includes models with or without integrated display, and models for standard gas, for hydrogen / helium, and for special gases ◾Operation at low differential pressure is a standard feature The MQV series does not use capillaries that have large pressure loss. This way the MQV series can control at low pressure differences ◾The MQV series comes with a multitude of standard functions such as flow rate indication and totalizing. Without the need to process software like a PLC, the MQV series handles a wide range of applications with ease ◾PC loader communications functions A convenient personal computer loader function has been integrated as a standard feature. The MLP loader software, which is sold separately, allows not only configuration of various settings, but also monitoring of flow rate trends and other operating status information on the PC screen. Acquired data can also be saved as a CSV file ◾A variety of available input and output signals Switch between 3 inputs and between 2 event outputs RS-485 communications (optional). Dedicated port for connection to a PC ◾Can be connected to a regular 24 Vdc power supply The internal power supply circuit of this device is isolated from its analog circuits. When multiple MQV's are controlled by PLC analog input / output, even if the analog module of the PLC is not isolated between channels, a common power supply can be used. Even without individual power supplies, there is no negative effect from surrounding circuits. An AC adapter (100 to 240 Vac) is also available by separate purchase ◾Engineered for flexible installation The display direction on models with an integrated display can be changed 180 degrees ◾Wide temperature range As a product developed for general industrial markets, the MQV series can be used from -10 to +60 °C (ambient temperature and gas temperature)
