Avionics Digital Panel Meter

June 1, 2014

Specifically designed to replace “needle” meters in military aircraft, the new APM model from OTEK Corp. (Tucson, AZ) conforms to military and commercial 1"-diameter standards, as well as a variety of Mil-Standards, including 461, 704, 130, 810, and 889. The APM accepts 4-20mA or VDC signals (others upon request), 0-5VRMS/VDC for intensity (dimming) control, and 5-48VDC power input. The 4-digit (9.9.9.9) display is standard or NVG3-compliant. For new applications (not yet military-approved), the APM can be loop powered, eliminating the need for external power supply and wiring. The < 100mW loop power adds a burden under 5 VDC max to the loop, and has an operating range of 3-36mADC.
