  • Limit values adjustable within the speed range 1...65535 rp

Application


*The MMS 3311 speed / key pulse Transmitter serves the measurement of shaft speeds and the generation of key pulses. Generation of key pulses is realised by using a toothed wheel or a trigger mark on the machine-shaft. 

*Both channels may be operated independently from each other. 

*Application areas for the MMS 3311 transmitter are all kinds of rotating machines where speeds resp. key pulses shall be measured e.g. at turbines, fans, compressors, gear boxes, pumps, coal mills and similar machines.

*MMS 3000 transmitters are used as well in big systems with PLCs and host computers as used in power plants, refineries and chemical plants as also in smaller systems with only few measuring points and decentral data processing. 

*The inputs of the MMS 3311 transmitter may be operated with standard epro eddy-current sensors PR 6422/.., PR 6423/.., PR 6424/.., PR 6425/.. The transmitter must not be used for applications in hazardous areas.
