ENM Co. Model PT14 is a self-powered digital tachometer/maintenance on-time hour meter for all types of gasoline engines. True engine rpm to 48,000 and actual running time to 9999.9 h are logged on an LCD in this compact unit. A 35,000-h, continuous running, internal lithium battery powers the device. The operation of the unit is actuated by a shielded lead wire wrapped around a spark plug wire on the engine block.
Foot pedals and ratcheting brake levers from Wescon Products Co. are designed for off-road, utility, and heavy-duty vehicles. The brake levers are available with either horizontal or vertical cable pull. The foot pedals, which can be used in braking and in friction and hydraulic accelerator control, include pedal configurations such as stamped metal, nylon reinforced with fiberglass, cast iron, and aluminum.
Series 650 Capacitive accelerometers from the IMI Sensors Div. of PCB Piezotronics, Inc. use precision capacitive sensing elements for vibration monitoring of large machinery, slow rotating rolls, and heavy equipment, as well as for structural integrity and foundation testing. Features include strong output signals, low noise operation, and ability to measure true dc acceleration.
The Model DSP6001 high-speed dynamometer controller from Magtrol Inc. uses digital-signal-processing technology for motor testing capabilities. The device features a built-in alarm system, digital analog converter capabilities, and two channels. It is designed for use with the firm's hysteresis, eddy-current, or powder brake dynamometers, in-line torque transducer, or complimentary auxiliary instrumentation.
The ECI Proportional Fan Drive from Horton has a two-speed design that reduces noise, drains less power, and heats or cools cabs better than traditional direct fan drives. The intelligent ICI switches between eddy-current (low speed) and electric (high speed) operation to deliver the exact cooling an engine needs. The device is suited for cooling agricultural and construction equipment, skid steer loaders, and other off-road machinery without ram air.
