The CMT800H Vibration Transmitter (1 or 2 Channel) is microprocessor based fully programmable device, designed to meet industrial environment. Linear Power Supply is deployed for low noise and is very reliable. All the units undergo stringent tests to assure quality performance Large Fans and Blowers (ID, FD, SA, PA etc.) are used in process plants for moving air or gases; they are essential for cooling, heating or transporting product. They usually are centrifugal or axial driven and commonly develop erosion and/or corrosion and/or deposition on the blades. This results in a progressive increase in vibrations. And build-up of dirt or cake on a fan’s impellor is quite normal. However, not always are these faults progressive and predictive but, should a dirt piece become detached then suddenly the rotor becomes out of balance, and if ignored, consequential damage to the drive motor’s bearings and coupling will results.
This can be extremely destructive and threaten personnel and plant safety. The loss of a single line Fan or Blower can shut down the process causing significant production and financial losses. The re-transmission analogue signal can be trended in DCS/PLC to monitor defect progression and plan maintenance considering production schedule and fix the problem before catastrophic failure.
RS485 Modbus RTU or GSM or RS232 connectivity is also available as an OPTION.
