Note
Do not mount SITRANS WM300 MFA in direct sunlight.
The SITRANS WM300 MFA can be DIN or wall mounted. In a stand-alone enclosure or
panel arrangement, the device can use a power transformer to take AC to DC voltage. An
additional NCT analog output module is necessary to be integrated into the SITRANS
WM300 MFA bus connection and additional RMA depending on the application
requirements.
3.3 Proper Mounting
The probe should be mounted onto a vibration free structure using the mounting flange. The
gap between probe and target should be large enough to prevent the target from damaging
the probe. The probe environment must be within the probe's ambient temperature range
and non-corrosive to the probe's body. Refer to Applications (Page 71).
The probe design detects a changing magnetic field, typically caused by a ferromagnetic
target disturbing the probe's magnetic field. Extremely strong magnetic fields (like those
produced by the 30 A/m requirements of 1EC 60004-8, Power Frequency Magnetic Field
Immunity test) will be detected and will result in loss of functionality.
