Rotary inductive position sensor is accurate, roust and economical
Pewatron is launching the P500 RIPS (Rotary Inductive Position Sensor), which it describes as a durable, affordable, high-accuracy rotary sensor for industrial and scientific feedback applications. It is supplied with the output calibrated to the angle required by the customer, between 20 and 160 degrees. The sensor provides a linear output proportional to the angle of rotation, with a non-linearity at 100 degrees of better than 0.25 degree.The standard version is powered by a 5V supply, giving an output signal of 0.5-4.5 V. Optionally, there are several output stages available for signals of 0.5-9.5V, +/-5V, +/-10V or 4-20mA (two or three wires), which are powered by +/-15V DC or 24V DC typically. The operating temperature range is -40 to +125 degrees C for the standard version (5V, unbuffered) and -20 to +85 degrees C for the buffered versions.
P500 sensors have a rugged stainless steel body and shaft for a long service life and environmental resistance. They are easy to install, with flange or servo-mounting options in anodised aluminium (or stainless steel for the E500). Sealing is to IP67 (for the cable version) or IP65 (for the connector version), and full EMC protection is built in.
Sensors are also available in intrinsically safe versions, designed for use with a galvanically isolated three-port barrier installed in the safe area to supply the sensor with 5V at a cable length up to 150m. There is a choice of 0.5-9.5V (Model BX002) or 4-20mA (Model BX003) transmission outputs from the barrier. To ensure an exact calibration, the sensor and barrier are calibrated directly at the factory.
The X500 model is Atex-approved to EX II 1G for use in potentially explosive gas/vapour atmospheres, while the E500 is IP67 and Atex-approved to EX II 1GD for use in potentially explosive gas/vapour, dust atmospheres.
