Need help with monitoring a set of bearings on the roof top dust collector fan unit. Have access to CTC Pro Lp300 sensors, AB-850 w/analog input module or a 1400 with analog input. Need help with logic monitoring thresholds of each bearing if its possible. Has anyone accomplished this on the cheap like I'm tasked with doing? We have handheld monitors but I'm not wanting to send my technician up on the roof all the time to gather 20 minutes of data every week so I'd like to monitor the 4-20mA with a plc and alarm off when we hit a predetermined threshold. Is it possible with this hardware, and if it is, what is the best way to do it? I thought about scaling the analog to a 0-100 (percent), setting a threshold of say 60 (whatever our threshold is from baseline) and alarming off if it gets above that mark for "x" amount of time.
Would this work and is this the best way to write the logic?
Thanks
