Rotary Variable Differential Transformers (RVDT) by Positek, Ltd

P500  is a durable, affordable, high accuracy rotary sensor designed for industrial and scientific feedback applications. The P500, like all Positek sensors, is supplied with the output calibrated to the angle required by the customer, between 16 and 160 degrees. The sensor provides a linear output proportional with angle of rotation. There is a machined registration mark to identify the calibrated mid point.

It is particularly suitable for OEMs seeking good sensor performance for arduous applications such as industrial machinery where cost is important.

Overall performance, repeatability and stability are outstanding over a wide temperature range. The P500 has a rugged stainless steel body and shaft for long service life and environmental resistance. The mounting flange is anodised aluminum. The sensor is easy to install with flange or servo mounting options, it also offers a wide range of electrical options. Sealing is IP65 or IP67 depending on selected cable or connector options, and full EMC protection built in.

Positek offers a range of options for its standard sensors. Each sensor is manufactured to suit each customer's preferences. If your requirement is outside the options given below, Positek can modify/ redesign a sensor to suit your specific requirement. Standard options are available as below:


Measurement Range

Factory set to any length from ±8° to ±80° in increments of 1°. For example, if your application requires 90° measurement, then Positek will manufacture the sensor specifically for this angular range. The sensor will measure 90° however will still rotate through 360°.
