Item #291B280A17, Weschler Conventional Analog Panel Meters - AC Voltage & Current
AC Panel Instruments Types 351 (3-1/2”), 371 (4-1/2″) Round and Rectangular
Weschler NA-351, NA-371, NC-351, NC-371, RA-351, RA-371, RC-351 & RC-371 meet all performance requirements of ANSI C39.1-1981 for round and rectangular panel instruments. They employ conventional Taut Band mechanisms enclosed in black fluted cases designed to match the appearance of Westinghouse switchboard instruments and relays and other devices used on traditionally styled control panels.
Features
High Torque To Weight Ratio: Ensures rapid, accurate readings with high damping and minimum frictional effect. Easy To Read Scales: Linear on dc. Virtually linear above 10% of full scale on ac. Self Shielding: DC types are magnetically shielded and calibration is unaffected regardless of material or thickness of the mounting panel.
