• Key pulse output 

*The Speed- and Key-Transmitter MMS 3311 is part of the revised MMS 3000 transmitter system for monitoring and protecting any kind of turbo machines. 

*The transmitters of the new generation are characterized by their highly flexible hardware options and their versatile combination possibilities and can thus optimally be adapted on the demands of the respective plant. They permit economic measurement and supervision of speed and generation of key pulses. 

*Application fields of the MMS 3311 transmitters are all kinds of rotating machines, e.g. turbo machines, fans, compressors, gear boxes, pumps and similar, rotating machines. 

*MMS 3000 transmitter are applicable for big systems with programmable logic controls and host computers as used in power stations, refineries and chemical plants, as well as for small plants with only few measuring points and decentralized data processing. 

*The inputs of the transmitter may be operated with all standard types of epro eddy current sensors: 

PR 6422/.., PR 6423/.., PR 6424/.., PR 6425/.. 

*The transmitter MMS 3311/xxx-xxx contains the following additional functions, which can be used depending on the configuration of the transmitter: 

*Zero speed and rotational direction detection : If the transmitter does not receive pulses within a certain time period, the transmitter recognises this as machine-standstill and indicates it via a function output. 

*When using two speed sensors, it is possible to detect the rotational direction of the machine. 

*The detected direction is indicated via a function output. 

*Redundant modus (speed): This mode requires two speed sensors. 

*Both sensors provide their signal to the transmitter inputs. 

*In case of an error, the program switches automatically to the second, redundant sensor. 

*Dual current mode: This function splits the output current in two ranges. Example: Measuring range 0...3000 rpm. *One part of this range, e.g. 0...300 rpm, is scaled to 0/4...20mA. Having exceeded the limit of 300rpm, the total measuring range of the transmitter will be scaled to 0/4...20mA.
