Profile: AI-TEK Instruments, LLC designs and manufactures electronic and electromechanical products which protect, monitor & control. We are an ISO 9001 and AS 9100 certified company. We offer fast response and high-precision tachometers for monitoring & protection. We supply magnetic speed sensors to the industrial, machine tool, petrochemical and aerospace industries. Our tachometer transducers are self-generating units when used with speed sensors. They are designed primarily to provide an easy means of attaching a pulse generating assembly to rotating shafts. Sensor gapping, shaft run-out and mounting problems are eliminated. This makes the unit especially useful for shafts with high run-out.
