SITRANS WM300 MFA Overview SITRANS WM300 MFA is a highly sensitive, dual setpoint motion sensor alarm unit, used with MSP and XPP probes. The probe detects an increase or decrease in the speed of rotating, reciprocating, or conveying equipment and sends the information to the SITRANS WM300 MFA.
Installing/mounting Safety Note Note Installation shall only be performed by qualified personnel and in accordance with local governing regulations. Location Requirements The SITRANS WM300 MFA (and RMA or NCT and power supply converter if applicable) must be mounted in a non-hazardous area that is clean, dry, vibration-free, within the ambient temperature range, and non-corrosive to the electronics or its enclosure.
Installing/mounting 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.

Technical Reference Principles of Operation SITRANS WM300 MFA SITRANS WM300 MFA is a highly sensitive, dual setpoint motion sensor alarm unit, used with MSP and XPP probes. The probe detects an increase or decrease in the speed of rotating, reciprocating, or conveying equipment and sends the information to the SITRANS WM300 MFA.

Technical Reference A.1 Principles of Operation The relationship between speed and gap of a standard probe ① Fig. a ② Fig. b ③ Fig. c The resultant line indicates the threshold tolerance of the accompanying SITRANS WM300 MFA electronics. For example, in Fig. a, a 100 mm (4 inch) gap requires a minimum velocity of about 10 m/minute (35 ft/minute): with a velocity of 0.61 m/minute (2 ft/minute), a maximum gap of 31 mm (1.25 inch) is possible.
