Henschel Corp. Offers Literature On New Digital Shaft RPM Indicators

Precise digital presentation of shaft speed and direction of rotation is provided by these new digital shaft RPM indicators by Henschel.

Two models are available: one for shaft speeds of 0 to 199 rpm, the other from 0 to 999 rpm. Forward motion is displayed in big, easy-to-read LED figures. Astern rotation is indicated by a blinking minus sign immediately preceding the digits. A dimmer control is provided for dark-adaptation convenience.

Enclosed in a drip-proof castaluminum case, these units are designed for panel, console or bulkhead mounting.

Driven by a standard shaft speed transmitter and powered by 115 VAC-60Hz, these digital shaft speed indicators can be used alone, with other similar remote reading unit, or in a system containing voltmeter (dial) type units with degradation of the system's plus/ minus 1-rpm accuracy. Standard scale factor is 7.2 VDC per 100 rpm. Other scaling factors can be provided. The operating range is 0 degrees to 50 degrees centigrade.
