AI-TEK T77530-10 TACHPAK® 30 Series Dual-Channel Digital Process Tachometer

The AI-TEK T77530-10 is a premier member of the TACHPAK® 30 Series, a family of advanced dual-channel digital process tachometers designed for industrial rotating machinery monitoring and protection . Manufactured by AI-TEK Instruments (formerly AIRPAX), a company with over 60 years of experience in speed sensing technology, this microprocessor-based instrument represents the gold standard for precision speed measurement, control, and alarm applications .

As a computing tachometer housed in a compact standard enclosure with DIN rail mounting, the T77530-10 measures input frequencies from two independent sensors and converts them into multiple output formats including analog signals, relay functions, and RS485 communication.
