3.3 Proper Mounting
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 64).
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 IEC 60004-8, Power Frequency Magnetic Field
Immunity test) will be detected and will result in loss of functionality.
Functionality loss indicators:
• Alarm conditions by relay output
