AI-TEK 70085-1010-249 Hall Effect Speed Sensor Product Description

OverviewAI-TEK 70085-1010-249 is a high-performance hall effect speed sensor manufactured by AI-TEK, a well-known brand for rotational speed monitoring. AI-TEK 70085-1010-249 detects the rotational speed of gear teeth or target bolts and outputs square wave pulse signals, which can be directly connected to speed monitors, PLC and DCS systems for rotating machinery speed measurement and overspeed protection. It is widely used in turbines, compressors, generators, pumps and fans. In recent overseas power and petrochemical projects, AI-TEK 70085-1010-249 serves as a core speed acquisition component for critical rotating equipment, supporting reliable speed monitoring and interlock protection. This hall effect speed sensor is a classic imported spare for heavy-duty rotating machinery monitoring.

FeaturesAI-TEK 70085-1010-249 adopts hall effect sensing technology, no magnetic drag effect and can work with non-magnetic targets under certain conditions. The hall effect speed sensor features stable pulse output, good anti-vibration and high-temperature resistance. It has built-in reverse polarity protection and short circuit protection for the circuit. The sealed stainless steel housing provides excellent mechanical strength and corrosion resistance. Threaded body design is convenient for gap adjustment during field installation. AI-TEK 70085-1010-249 can match various speed monitoring modules and overspeed protection systems, and complete test reports are available for project acceptance.

SpecsAI-TEK 70085-1010-249 hall effect speed sensor. The hall effect speed sensor sensing principle: hall effect. Output signal: square wave pulse. Sensing target: ferrous gear tooth or bolt target. Housing material: stainless steel. Mounting: threaded installation. Cable: integrated or flying lead. It is stocked as rotating speed monitoring spare.

Operating ParametersAI-TEK 70085-1010-249 supply voltage: 8–30V DC. The hall effect speed sensor ambient operating temperature: -40℃ ~ +125℃. Relative humidity: ≤95% non-condensing. Protection class: IP67. Working air gap: adjustable within the specified range. EMC: meets industrial heavy interference standards.

PrincipleAI-TEK 70085-1010-249 detects the change of magnetic flux when the gear tooth passes the sensing head. The hall effect speed sensor converts magnetic flux variation into square wave pulse signal. The pulse frequency is proportional to the rotational speed of the target. The rear speed monitoring unit calculates the actual rotation speed by counting pulses. The internal circuit continuously monitors the working state; if signal loss or power supply abnormality occurs, AI-TEK 70085-1010-249 stops pulse output and triggers fault alarm on the host side.

ApplicationsAI-TEK 70085-1010-249 is widely deployed in thermal power plants, refineries, chemical plants, gas compression stations and marine power systems. The hall effect speed sensor is used for speed measurement and overspeed protection of steam turbines, centrifugal compressors, generators and large pumps. It cooperates with speed monitoring instruments, safety protection systems and DCS to realize speed interlock and shutdown protection. AI-TEK 70085-1010-249 is a preferred imported spare for critical rotating equipment speed loops.
