Stop-Time Measurement (STM) Device Complete (DCL100)

Complete STM including meter, transducer, cable extension set, actuator, flag, legs, and plunger extension.

The stop-time measurement (STM) device measures the time it takes a machine to stop after a signal is given. It is mainly used on reciprocating (stroking or cycling) machines, such as mechanical or hydraulic presses and press brakes. With optional accessories, it can also be used on machines that rotate, such as lathes, mills, and drills.

Industry uses this type of device to determine the stopping time of a machine before installing safeguarding devices such as a two-hand control or a presence-sensing device. The stopping time measured by the STM device during the hazardous portion of the cycle is used in the OSHA (Occupational Safety and Health Administration) or ANSI (American National Standards Institute) formulas to calculate the safety distance. The safety distance is then used to establish the location of the safeguarding device in relation to the nearest hazard. This device can also be used to periodically check the machine’s stopping time to ensure that the current safety distance corresponds to the current condition of the machine’s stopping ability.
