Submersible Linear Sensors

Positek’s portfolio includes a range of high-accuracy linear sensors specifically designed for use in submersible applications. Made from marine grade stainless steel and offering the reliability that is not possible from a submersible LVDT or linear potentiometer, our sensors have served a host of different industries such as wastewater and offshore oil drilling. Another use […]

Torque Measurement with Angle Sensors

As collaborative robots expand into manufacturing environments the issue of safe motion continues to be a concern. Current design approaches involve adding force sensors, torque sensors, and sometimes proximity sensors. These adders along with more complex software control algorithms mitigate most of the concerns and result in slower operation. Unfortunately, these additional sensors also add significant cost and complexity.

Why Holistic Encoders are More Accurate

All absolute rotary encoders have a rotor which is attached to the rotating shaft and a stator which is attached to the housing holding the shaft. The interaction of these two components produces a measure of the shafts rotational angle. The most important parameters of absolute rotary sensors are resolution, accuracy and tolerance to misalignment of the rotational axes.

Improved Encoder Accuracy Brings Hidden Benefits

Capacitive rotary encoders such as those from Netzer Precision are known for their low profile, high noise immunity and excellent accuracy. As a result, they are an excellent choice for applications such as camera systems, radar, slip-rings and robotic joints. Often times in these tasks the encoder is used for velocity feedback, ensuring a smooth […]
