Mounting Clips install accelerometers.
Easy-Mount mounting clips may be attached to test structure using double-sided tape or adhesive. Once they are installed, accelerometers may be snapped into clips to make vibration measurements. Swivel-style clips rotate and pivot, permitting sensors installed on curved or sloped surfaces to be aligned along desired plane and axis.

Alarm Module signals machinery problems.
DIN-rail mountable Model 682A04 dual relay alarm module works with any 4-20 mA signal input. Its adjustable, 0-45 sec time delay makes it suitable for use with vibration signal inputs that directly output signal or with vibration transmitters that provide conditioned output signal from analog accelerometers. Time delay serves to eliminate false alarm trips due to momentary vibratory upsets,...
