use the same sophisticated remote monitoring systems and provide most of the capabilities of these systems - at a third to half the cost per monitor point, it’s announced.
They utilize a solid-state crystal accelerometer which provides an electrical output when it is deformed by vibration forces. Output is electronically converted to a signal proportional to velocity, which is compared with a preset limit to trigger a solid-state relay if limit is exceeded.
