70085 Series Passive Speed Sensors

Control and protection circuits have relied on variable reluctance technology for years. With few components and no moving parts, the passive magnetic speed sensors can provide a signal from the inside of an aircraft engine at temperatures approaching 425 degrees C or from the hub of an automobile wheel at high shock and vibration. These sensors have high reliability, are easy to install due to easy alignment and can be designed for almost any environment. Due to their flexibility, you ...

RH Series Speed Sensors

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect sensors for harsh applications and has developed a line of durable products for industrial, rail, military and automotive use.

The RH series are single-element based, zero speed, single channel speed sensors and are an excellent choice for general purpose speed sensing. Unlike the DH series that requires rotational alignment at installation, the RH series requires no alignment. Air gap adjustment is precise and easy and similar to a ...

DH Series Speed Sensors

The DH series are differential based, zero-speed, precision, single channel, speed sensors. At power-up, they calibrate themselves to the unique magnetic signature of their installed application and continue to update the calibration as the sensor is running. This unique combination of differential sensing technology and calibration make these sensors highly tolerant of installation misalignment, target geometry and composition, target run-out, vibration and air gap changes. The DH sensors sense each change in target movement, regardless of speed, from near zero ...

BH Series Speed Sensors

Th BH series Bi-directional, zero velocity sensors are self-calibrating to the specific customer application and provide two independent frequency outputs and a direction signal output to indicate change in direction of the sensed, ferrous target. The sensors can also be referred to as a dual channel sensor since they utilize two Hall effect sensing elements, physically offset from each other. Each element generates a single channel of target information, identical in frequency and polarity, but offset in the time domain ...

Tachtrol Tachometers

The Tachtrol digital display tachometers are dual channel instruments that measures input frequency and convert the resulting quantities to an analogue output, and implement utility RS485 communication, solid state & mechanical relay functions. These instruments accept a wide range of AC or DC power and have greatly improved accuracy, processing speed and response time. They can be used in rate, period or counter mode and programming can be done via AI-Tek’s Tachlink, or through the integrated display panel. Typically, they ...

Tachtrol20 Tachometer

The Tachtrol20 is a single input digital display tachometer designed for any rate measuring application. Configurable to display application-specific rate information in raw frequency or engineering units such as RPM and FPM, the tachometer can accommodate magnetic pickups, logic sensors and NPN open collector sensors and is programmed through both the front panel buttons and DIP switches. With a NEMA4X/IP65 sealed bezel and extensive testing to meet CE requirements, the Tachtrol20 has been specifically designed for harsh industrial environments.
