4-20 mA Vibration Monitoring of Chillers and Cooling Units
|
From Wilcoxon Research
4-20 mA vibration monitoring of chillers and cooling units Cooling towers, process coolers and HVAC cooling units can be monitored for vibration using the 4-20 mA analog input channels of existing PLC units. Control system data input Most modern chiller and cooler systems are operated by a process control system, such as a Programmable Logic Controller (PLC). PLCs have the ability to accept 4-20 mA analog input signals. Plants that utilize a PLC for operation often utilize this capability to achieve the cost savings of online vibration monitoring by sending 4-20 mA analog vibration data directly to their PLC.
