Continuous measurements on industrial machines or the materials that these machines are making, moving, or processing can be categorized into two main types of sensors: position measurement sensors, and distance measurement sensors. It’s a somewhat subtle distinction, but one that … Continue reading
Linear encoders – absolute or incremental? Incremental encoders are simple, inexpensive, and easy to implement, but they require that the machine be homed or moved to a reference position. Absolute encoders don’t require homing, but they’re usually more expensive, and … Continue reading
External Linear Position Sensors: Floating or Captive Magnet? Linear position sensors that are designed to be mounted externally on a machine (as opposed to those designed to be installed into a hydraulic or pneumatic cylinder) are available in a variety … Continue reading
Linear position sensors that provide continuous, typically analog, feedback are used extensively in a variety of applications in many different industries and markets. Linear position sensors employ various technologies, but at the most basic level the technologies can be classified … Continue reading
In a previous Sensortech post entitled “Hydraulic Cylinder Position Feedback“, we discussed the basic concept of hydraulic cylinder position feedback. In case you might have missed that post, here it is for an encore appearance. Magnetostrictive linear position transducers are commonly … Continue reading
In a previous entry here on the SensorTech blog, we discussed the concept of liquid level sensing, and the difference between discrete liquid level detection and continuous liquid level monitoring. In this entry, we are going to talk about the … Continue reading
