AI-Tek Instruments (formerly Airpax) is a premier manufacturer of high-precision speed sensing and control solutions, essential for monitoring rotating machinery in power generation, petrochemical, and aerospace industries. This series specializes in magnetic pickups and Hall Effect sensors designed to withstand extreme temperatures, high vibration, and corrosive environments. AI-Tek tachometers, including the Tachtrol 10 and 30 micro-processor-based instruments, offer rapid response times and field-programmable logic for overspeed protection and rate monitoring. Their sensors utilize specialized housing materials and potting compounds to ensure signal integrity across wide air gaps and variable speeds. Whether integrated into a Bently Nevada vibration system or used as a standalone safety governor, AI-Tek components provide the millisecond-accuracy required for critical turbine and motor diagnostics.
