Dual color with sub display at a glance
CE Approved
CE : EMC Directive
The setting conditions are displayed on the sub display, making it much easier to keep track of operations.
In addition, the digital display which switches between 2 colors lets you check the status of sensor operation at a glance.
A new rectification mechanism and Micro Electro Mechanical System (MEMS) technology allow the sensor to be mounted on a Si sensor chip (3 x 3.5 mm0.118 x 0.138 in). This provides an extremely small heat capacity, high precision of ±3 % F.S. and high-speed response. The two temperature sensors on each side of the heater detect the heat distribution to make bidirectional detection possible.
A single sensor can detect flows bidirectionally. In addition, it can be set to detect flows in either the forward or reverse direction only, making it suitable for a variety of applications.
The rectification method used by the new mechanism makes straight pipes unnecessary at both the intake and exhaust sides.
Quick connection is possible with a cover-attached connector.
Other than the ability to carry out bidirectional detection, there are no limitations on the installation direction, making the installation very flexible.
The FM-200 series can control and manage flows in a wide variety of output modes such as integrated output mode, depending on the required application.
Integrated output mode
■ Quality control
When the volume of flow of the gas being measured reaches the set integrated value, output switches to ON or OFF.
・Controls N2 charging volumes for electronic components
・Controls air blowing volumes, etc.
Integrated pulse output mode
■ Cost management
The pulse output is generated once at every specified integrated value*. This lets you know the amount of air consumed per unit of time easily.
* Integrated values are specified by range and can vary. For details, refer to “SPECIFICATIONS”.
・Controls N2 purge volumes in reflow furnaces
・Controls overall volumes of air consumed by equipment, etc.
■ Energy-saving and environmental-friendly
The pulse output from the flow sensor can be inputted to the pulse counter of an Eco-Power Meter so that air consumption and power consumption can both be measured simultaneously.
Notes:
1) Displayed value data is not outputted.
2) For details, refer to “KW8M Eco-Power Meter”.
