Use of Magnetic Tools with the DVC6200
D Magnetic Tip Screw Drivers – Magnetic tip screw drivers can be used to work on the DVC6200. However, they should
not be brought in close proximity to the magnet assembly (located at the back of the instrument) during process
operations.
D Calibrator Strap Magnets
– These are high power magnets used to hold 4-20 mA calibrators. Normally,
these calibrators would not be used while an instrument is controlling the process. High power magnets
should be kept at least 15 cm (6 inches) from the DVC6200.
Note
D
The mounting instructions also apply to the DVC6215 remote mount feedback unit.
D
As a general rule, do not use less than 60% of the magnet assembly travel range for full travel measurement. Performance will
decrease as the assembly is increasingly subranged.
D
The linear magnet assemblies have a valid travel range indicated by arrows molded into the piece. This means that the hall
sensor (the center point of the channel on the back of the DVC6200 housing) has to remain within this range throughout the
entire valve travel. The linear magnet assemblies are symmetrical. Either end may be up.
D
The magnet assembly may be referred to as a magnetic array in user interface tools.
D
Mounting the instrument vertically, with the vent at the bottom of the assembly, or horizontally, with the vent pointing down, is
recommended to allow drainage of moisture that may be introduced via the instrument air supply.
