R36AS DC rvdt for harsh environments

R36AS DC rvdt for harsh environments

The R36AS RVDT (Rotary Variable Differential Transformer) is an angular position sensor that incorporates a proprietary noncontact design which dramatically improves long term reliability when compared to other traditional rotary devices such as synchros, 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 stator coil that together simulate the operation of a Linear Variable Differential Transformer (LVDT). Rotational movement of the rotor shaft results in a linear change in the amplitude of the output signal, directly proportional to the shaft angle change, while the phase of this signal indicates the direction of displacement from the null point.

Description

The R36AS RVDT (Rotary Variable Differential Transformer) is an angular position sensor that incorporates a proprietary noncontact design which dramatically improves long term reliability when compared to other traditional rotary devices such as synchros, 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 stator coil that together simulate the operation of a Linear Variable Differential Transformer (LVDT). Rotational movement of the rotor shaft results in a linear change in the amplitude of the output signal, directly proportional to the shaft angle change, while the phase of this signal indicates the direction of displacement from the null point. Non-contact electromagnetic coupling of the rotor provide infinite resolution. AC operation eliminates the need for integrated signal conditioning components, thereby offering the user a very wide operating temperature range of -55°C to +150°C. Factory calibrated to operate over a ±30 degree range, the R36AS offers a non-linearity of less than ±0.5% of full range. Extended range operation up to a maximum of ±60 degrees is possible with increased non-linearity. Packaged in Size 15 servo mount stainless steel housing, an MS style hermetic connector, and a shaft seal, the R36AS is the perfect choice for angular position sensing in harsh environments.
