Product:EPRO MMS3120/022-000 Dual Channel Bearing Vibration Transmitter

Germany EPRO

PR6422 / PR6423 / PR6424 / PR6426 eddy current sensor, PR9268 series of electric absolute vibration sensor,MMS6000 system.

Measuring systems with eddy current transducers serve the measurement of mechanical quantities, such as shaft vibration and shaft displacement. Applications with such systems can be found in different industrial areas and laboratories. Due to the contactless measuring principle, small dimensions, a rugged construction and the endurance against aggressive media, this type of sensor is optimally suitable for the use at all kind of turbo machines. epro offers a wide range of devices for measuring and monitoring. Measuring quantities are e.g.: - Air-gaps between rotating and stationary parts - Vibrations of machine shafts and housing parts - Shaft-dynamic and eccentricity - Deformation and deflection of machine-parts - Axial and radial shaft displacement - Abrasion and position measurements at thrust bearings - Thickness of oil film in the bearing - Differential expansion - Housing expansion - Valve position Construction and dimensions of measuring amplifier and relevant sensors apply to international standards, e.g. API 670, DIN 45670 and ISO 10817-1. At connection via safety barriers, sensors and signal converters may also be operated in hazardous areas. The certificate of conformity according to the European standard EN 50014/50020 has been submitted.

Applications:
The MMS 3120 dual channel
bearing vibration transmitter is part
of the MMS 3000 transmitter system
for monitoring and protecting
any kind of turbo machines. It
permits economic measurement
and supervision of absolute bearing
vibrations by using electrodynamic
vibration transducers.
Application fields of the system are
all types of turbo machines, fans,
compressors, gear boxes pumps
and other machines.
MMS 3000 Transmitters are
suitable 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 epro standard
bearing vibration transducers:
PR 9268/20 ../30 and
PR 9268/60 ../70
The transmitter is not designed for
the use in hazardous areas.
