PRAS20 Magnetic Angle sensor
Absolute magnetic angle sensor up to 360 degrees in a flat housing
• Non-Contact, external magnet
• Only 6 mm thickness
• 0.5...4.5 V ratiometric
|
|
|
The QR angle sensor is designed to measure non contact rotary displacement from 0 to 360 degrees without mechanical stop. A magnet needs to be fitted to the rotating axle and the sensor can be mounted opposite with a maximum 5 mm gap. This gives plenty of room for mechanical tolerances in extreme circumstances. In combination with our robust QUADRO® (PDF) housing you get a accurate sensor that withstands a few knocks. We supply a range of electronic input / output options with 8, 10 or 12-bits resolution to cater for the wide range of applications. Custom design housing with or without integrated magnet are an option.

ASM introduces new POSIROT® Magnetic 360° Angle Sensor
ASM GmbH has expanded its innovative line of POSIROT® angular position sensors with the introduction of a new magnetic angle sensor in a 20 mm (0.8 in.) flat, 36 mm (1.4 in.) diameter servo flange housing. PRAS2 is a dependable, contact-free and wear-free sensor that utilizes an external permanent magnet to measure complete angular position from 0° to 360° with a typical resolution of 0.1°.
PRAS2 models are available with three different analog outputs: 4-20 mA, 0.5-4.5 V and 0.5-10V. The angle measurement circuitry is shielded from external environment conditions. It has also been designed to be highly shock- and vibration-resistant.
With its low 20 mm (0.8 in.) height, this new compact model, PRAS2, can be quickly installed without requiring much space.
Since this sensor is in a rugged IP 68 stainless steel housing, it can reliably handle the toughest industrial environments and makes it suitable for many applications such steering and tilt angle measurement on mobile construction equipment.

The new 424Dxxx Angle Sensor from elobau features high precision paired with extraordinary robustness.
Depending on the model, it can execute angle measurements ranging from 20° up to a complete circle ranging from 0° to 359°.
The non-contact design provides exceptional reliability. The measurements are made with a magnetic field whose rotation is detected with a non-contact Hall sensor. Another benefit of this construction principle: the sensor does not require a limit stop. Thanks to its IP 67protection class, the sensor is protected against all effects of dust and water which may be present in industrial processes and in vehicles. Other features are short-circuit protection, electromagnetic compatibility as per DIN 40389 for automotive applications as well as high-quality and durable ball bearings for the rotating axis. Operating temperatures range from -25°C to +85°C (-13°F to +185°F).
The unit’s resolution of 0.1 degrees with a signal refresh rate of 300 Hz is evidence of it high accuracy. The angle sensor also features a highly homogeneous signal curve with a maximum linearity error of ± 1 percent. The analog output optionally ranges from 1 to 5 V, 4 to 20 mA or 0.5 to 4.5 V. With these features, the 424Dxxx Angle Sensor can be used for almost any mechanical or automotive engineering application.

AC operated Rotary Variable Differential Transformers (RVDTs) measure rotary position up to +/-60degs. Like AC LVDT’s they contain no signal conditioning and are therefore chosen for their smaller size and use in hostile environments.
Description: RVDTs incorporate a proprietary non-contact design that dramatically improves long term reliability when compared to other traditional rotary devices such as syncros, resolvers and potentiometers. This unique design eliminates assemblies that degrade over time, such as slip rings, rotor windings, contact brushes and wipers, without sacrificing accuracy. High reliability and performance are achieved through the use of a specially shaped rotor and wound coil that together simulates the linear displacement of a Linear Variable Differential Transformer (LVDT). Rotational movement of the rotor shaft results in a linear change in the output signal, directly proportional to change in shaft angle, over ±60 degrees from the null position. The phase of this output signal indicates the direction of displacement from the null point. Non-contact electromagnetic coupling of the rotor provides infinite resolution, thus enabling absolute measurements to a fraction of a degree. The R30A and R36AS RVDTs are AC operated rotary transducers. AC excitation of 3 V rms results in a ratiometric AC output voltage that varies in direct proportion to the change in angular position of the transducer shaft.

No One Protects Large Turbines like GE
The transducers in this category measure changes in machine case positions as they expand or contract, rotary or linear position of control valves, or wicket gate position on hydroelectric turbines. They are typically used in conjunction with other transducers as part of a Turbine Supervisory Instrumentation (TSI) package, designed to monitor all critical machinery parameters on large steam, gas, or hydraulic turbines used in power generation applications.
The 3300 XL Rotary Position Transducer (RPT)
This innovative transducer incorporates a proximity probe observing an eccentric cam. The changing gap between probe tip and cam corresponds to degrees of rotation, and is specifically designed for valve position measurements. It is a superior alternative to older potentiometer transducers which have poor reliability.

Rotary Shaft Encoders are ideal for use on any rotating shaft to provide a digital output signal to tachometers, counters, speed switches, motor controls, or anything requiring a pulse input. Flexible shaft couplings are available as an option to compensate for shaft misalignment, and are recommended for most applications.
Electro-Sensors Rotary Shaft Encoders convert shaft rotation into square wave output pulses. They provide an accurate means of transmitting actual speed information for detecting rate, position, or direction of rotation. The shaft encoder produces an output signal by rotating a disc with clear and opaque segments between a light emitting diode and a photo-transistor sensor. The output signal from the encoder is then converted into a square wave signal by an internal squaring circuit. The number of output pulses per shaft revolution is determined by the number of clear and opaque segments on the disc. Quadrature (bi-directional) models have a second LED and sensor positioned 90-degrees apart to produce two square wave signals.
Features:
- Ideal for Use on Slow Speed Applications
- Provides Precise Pulse Train for use with Tachometers, Counters, Speed Switches and Speed to Analog Converters
- Multiple Mounting Configuration for easy Installation
- Wide Variety of Pulse per Revolution Counts are Available
- Please Specify PULSES PER REVOLUTION (PPR) When Ordering
