IT6850 Impact Transmitter Calibrator

Metrix Impact Transmitters measure “Impact Severity”, defi ned as, the number of events (typically caused by mechanical looseness or detonation) which exceed the preset “threshold level” within a preset “pulse time period”.

The Impact Transmitter has a stepped 4-20 mA output that is proportional to 0 to 16 Impacts. The transmitter’s Threshold level and Pulse time may be adjusted to “fi ne tune” its response to the unique characteristics of the monitored equipment.

IT6810 / 6812 Impact Transmitter 6850 Operation / Operating Modes

The 6850 Impact Meter is designed for quick check out or adjustment of Metrix Impact transmitters, either on an operating machine, or with the transmitter removed.

Simply connect the Meter to an Impact transmitter, toggle the Power switch, and select Pulse-Time, 4-20mA, or Peak Detect mode. In Pulse-Time mode, the transmitter’s Threshold level (milli-volts), andSample Time (seconds) are displayed, and may be adjusted while observing the changes. Switching to 4-20mA mode displays the current output directly, while Peak Detect mode displays the peak vibration level, in milli-volts, detected by the transmitter.

The Peak Detect mode is provided for measuring and displaying the amplitude of Impact peaks present at the measurement location. Peak Detect mode is most useful when “fi ne tuning” a transmitter for a particular machine. An Impact Threshold Level 2X to 3X the base line PD level has proven to provide good machinery protection monitoring. While the Pulse Time is a function of machine operating speed, calculated as follows: 960 divided by machine RPM = the Pulse Time (in seconds).
