MCT Enveloped Acceleration.
Full scale option for all enveloped acceleration transmitter
units is factory preset to 10 gE. The Filter option is set to
Filter 3 (500 Hz to 10 Hz), unless otherwise specified in
the model number.
Transducer Cable
The vibration transmitter units provide power for the
transducer via a nominal 4.4 mA constant current source.
This is generally enough current to allow operation with
transducer cables extending up to about 100 ft. Longer
cables may be used, depending on the sensor and cable
specifications. However, it is strongly recommended that
the transmitter/monitor be mounted as close as practical
to the associated transducer. This will prevent signal
distortion associated with current drive limitations, and
will minimize interference from external electro-magnetic
noise sources (EMI). A well shielded, properly installed
transducer cable is necessary to obtain reliable operation.
Shielded twisted pair cables designed and pre-fitted with
the proper transducer connector or sensors with integral
cable, which are sold for this specific purpose, are
recommended. The cable shield should be open at the
transmitter end and connected to ground through the
sensor casing. Alternatively, the cable shield could be
