Process Digital Bargraph Display for Industrial Control and Automation
- 1. R DIXSON 071-40208C Application AMETEK Dixson bargraphs are appropriate in any application where moving pointer meters have been used in the past, and in applications where greater accuracy, readability, and reliabil- ity are desirable. Signal sensitivities span ANSI C39.1 ranges, all conventional current loops, and voltage control signals. An op- tional RS-422 serial data bus allows for distributed control sys- tem applications. The instruments are suitable for local or remote, primary or redundant system indication. The BB101P enclosure is form-factor compatible with stan- dard, 6-inch edgewise switchboard instruments and is a direct replacement for the GE/Yokogawa 180, International Sigma Model 1151/1251, Westinghouse/Weschler VX252, and the Modutech and Crompton 6-inch meters. This simplifies retrofit into existing systems without panel modifications. For control applications, the optional set point relay module provides on/off and differential gap control and annunciation using three set points. The optional digital display reads to 10 percent over- and underrange. An optional temperature measurement module makes the in- strument a direct-reading indicator for E, J, K, and T thermo- couples or 100-ohm RTD, and an optional retransmission module simplifies distribution of the temperature parameter throughout the system. User-programmability provides maximum versatility and mini- mizes the need for spares. A solid-state design with no moving parts yields a highly reliable product, especially under condi- tions of shock, vibration, dust and moisture. Features such as linearization, sensor power, retransmission, and min/max readings make the “PRO” Series the ideal choice for your application.
