DLI Watchman® ST-101 VIBRATION SCREENING TOOL ST-101 is a vibration screening tool that provides basic diagnostic capability at a very low cost. It's easy to use; designed for plant mechanics and machinery operators. The ST-101 will extend the capability of your operations and maintenance departments by providing clear, on the spot insight of your machine condition. Without specialized vibration analysis training, your personnel can assess your equipment condition and identify sources of potential machine problems. The ST-101 goes beyond the idiot light approach of traditional hand-held vibration meters. Green, yellow and red bar graph segments show acceptable/unacceptable representations of machine vibration. The bar graph displays indicate vibration levels based on Acceleration, Velocity and Displacement measurements. Simple patterns on the bar graph displays aid in the identification of underlying machine problems. In addition, a numerical display allows the user to log these readings for the purpose of historical data and machine condition trending. The user simply attaches the magnetic mount accelerometer to the machine, selects the operating speed of the machine and reads the display. Problems such as imbalance, misalignment and rolling contact bearing wear have never before been so quick and easy to detect and identify.

Benefits § Plant operators and maintenance technicians cannow alert predictive maintenance personnel of impending problems. § Monitor machinery traditionally too small or in-frequently run to be included in a predictive maintenance program. § Small facilities can now implement a low cost predictive maintenance program.

Specifications § Hand-held instrument for vibration monitoring and screening § Designed for monitoring simple machinery, including fans and air handlers, centrifugal, screw and rotary pumps, and other nonreciprocating machinery § For use by plant mechanics and machinery operators with limited vibration analysis experience § Bar graphs use proprietary methods to indicate faults and diagnostic information § Mechanical defects indicated by easy-to- understand bar graph patterns § Provides pass/fail results, and additional information for condition analysis § 4 digit readout reads acceleration, velocity &

displacement vibration levels, and information for trending § High-impact plastic case, water resistant § Powered by 4 AA alkaline batteries

Bar Graph Displays and Associated Machine Conditions

Smooth running machine. All indicators green.

Equal low and mid bar graphs indicate high rotational rate vibration level. Indicates balance or misalignment problem depending on orientation.

Mid bar graph 2 segments higher than low bar graph indicates high twice-rotational rate vibration level. This indicates misalignment.

Accessories Included • 100 mV/g single axis accelerometer • Magnetic accelerometer mount

• 10' coiled accelerometer cable • Four AA alkaline batteries

Mid bar graph higher than low or high bar graph indicates high vibration level between 2-9 times rotation rate. Usually caused by high vane or blade rate, indicating flow or wear problems.

High frequency bar graph has much greater levels than the mid bar graph. This is usually caused by failing rolling element bearings. Call DLI Engineering today to find out how your plant can benefit from the new DLI Watchman ST-101 Vibration Screening Tool.
