THE VIBRATION MONITORING SPECIALISTS PRODUCT INFORMATION PCH 1072 Mk2 Vibration Monitor PCH 1072 Mk2 Vibration Monitor Monitors the development of vibrations in a machine and gives an alarm if the vibration level is too high. PCH 1072 has easy and flexible set up possibilities for individual frequency ranges, alarms levels and delay times etc. by using the user software PCH Vibration Studio. Price attractive alternative For users who want to prevent their machines from damaging vibrations, e.g. vibrations coming from unbalance and misalignment. Bearing Damages A bearing damage often occurs due to undetected unbalance or misalignment of a machine. Hence the machine runs for a very long time period with a much too high vibration level. This is the most common reason for serious machine crashes and down time. PCH 1072 Mk2 in enclosure with options Avoid unscheduled production stops Deciding not to buy a vibration monitor due to price can be a very unwise decision. Often this leads to extra unexpected expenses to machine repairs, not to mentioned the further economic loss due to the production stop. Applications The PCH 1072 Mk2 Vibration Monitor can be used on many different machines in a production. It is very suitable for monitoring ventilators, fans, pumps, decanters, separators and mills where SIL 2 measuring chain is required. What does the PCH 1072 Mk2 Vibration Monitor The vibration monitor constantly keeps track of the machine vibration level. The vibration monitor has two adjustable alarms, which can be used to ensure that the machine vibrations do not exceed the acceptable or allowed limit. Hence the user obtains an active protection of the machine resulting in a considerable reduction of machine damages and accidents and thereby decreasing the maintenance expenses. Functionality The PCH 1072 Mk2 is a conditioning-, alarm– and output transmitter unit, with a aluminium housing. The monitor is equipped with an IEPE(ICP®) input for accelerometers. The PCH 1072 Mk2 monitors seismic mechanical vibrations according to DIN/ISO 10816-3. By using the PCH Vibration Studio software the PCH 1072 Mk2 can be configured to measure Velocity (mm/s), Acceleration (m/s2) or Displacement (µm/mm). Versions for moving-coil/Velocity Sensor or proximity probes are available as well. Measurement Range and Alarm Limits can be adjusted directly in the PCH 1072 Mk2 according to the machine type and size, it has to monitor. The present vibration level is constantly compared with the two Alarm Limits and if the Alarm Limits are exceeded the two Alarm Relays Alert/Danger will trigger and thereby inform the user, e.g. via a connected rotor light, beeper, controller or by directly shutting down the machine. Both Alert and Danger have user defined Delay Time, which prevents false alarms due to momentary transients. The integrated Test function can be activated from customer PLC or by a switch. Also the PCH 1072 Mk2 offers the option of a Latch function, ensuring the Alarm Relay stays triggered until it has been manually/remotely reset, even though the vibration level has decreased again. PCH 1072 Mk2 also provides a 4-20 mA signal, which expresses the relative vibration level.
