Digital Instrumentation

Over 35 years of design and application experience in engines and critical
machinery
Comprehensive understanding of ignition energy and its use as an instrument power source
Wide range of available instruments permit use in a variety of applications
Virtually all products certified for use in hazardous areas

Designed and manufactured in Girard, Ohio USA Altronic's digital instrumentation line began in 1977 with products designed to complement the already-established andsuccessful line of Altronic ignition equipment. In the following year, Altronic pioneered and patented the digital annunciator safety shutdown system to offer reliable protection to stationary gas engines, generators, compressors, and other critical rotating equipment.

This innovative system, and its successors, replaced a number of outdated electro-mechanical relays with one small, electronic unit operating with non-incendive circuits. Its high reliability, moderate cost, and simplicity of use have made it the industry standard for remote field compressors powered by natural gas engines. Current models include advanced features such as complete application configurability, comprehensive communications, and a simple means of integration into remote monitoring systems.

A complete line of digital monitoring devices is available for integration into Altronic annunciator systems, for stand-alone service, or for use in conjunction with other non-Altronic monitoring and control systems.

A partial list includes single and multipoint digital temperature gauges and scanners, pyrometers, pressure gauges and monitors, tachometers, and overspeed, and hourmeter devices. All are engineered and manufactured by Altronic offer the highest levels of quality for demanding, critical service applications as well as suitability for use in environmentally harsh or hazardous areas.

Design Principles

Altronic digital instrumentation has been developed with the following design principles in mind:

Low power source consumption and power source flexibility
Many Altronic digital instruments are designed to operate on very small amounts of power, often supplied by the engine ignition system. This permits instrument operation at all times, particularly during the critical start-up phase. Altronic offers the most comprehensive line of digital instrumentation powered directly from capacitor discharge (CD) ignition systems.

Hazardous area design
Non-incendive, non-arcing intrinsically safe instruments are offered for operation in hazardous areas. Innovative design techniques render these instruments safe for use in such areas without the need for or expense associated with explosion proof enclosures or purging systems.

Reliability and noise immunity
Often applied in areas exposed to high levels of electromagnetic interference (EMI), and radio-frequency interference (RFI), Altronic instruments are engineered and constructed to offer reliable, accurate service in high noise areas.

Corrosion resistance
Corrosion-resistant enclosures and finishes, gasketed seals, stainless-steel hardware, and conformally-coated printed circuit board assemblies insure continued service in harsh operating environments.
