MMS3311/022-000 EPRO Speed and Key Monitor

Description:

The Speed- and Key-Transmitter MMS3311/022-000 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 MMS3311/022-000 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 mustn't be used in hazardous areas.

Features：

Frequently Asked Questions:
1.What is the MMS3311/022-000 power data?
Option for redundant power supply, decoupled via diodes. 
Nominal: +24 V DC 
Permissible voltage range: +18...31,2 V DC
Power consumption: Depending on the built-in options. max. 6 W

2.What are the MMS3311/022-000functions and design?
The Speed- and Key-Transmitter MMS 3311 measures the shaft speed and generates key pulses. A trigger wheel or a key mark on the shaft is required for measurement of the speed and generation of the key signals. Both channels can be used independently from each other. Channel 1 is used for speed measuring and channel 2 for generation of key pulse.

3.What is the payment term?
Only wire transfer

4.When does the warranty period start?
One year from the time the client receives the goods.
