Renishaw, the global metrology specialist, launches the innovative FORTiS enclosed linear absolute encoder series, for use in harsh environments such as machine tools. The FORTiS design is built upon industry-proven RESOLUTE encoder technology and provides high resistance to the ingress of liquids and solid debris contaminants. It features an extruded enclosure with longitudinally attached interlocking […]
Encoders + sensors (linear) + I/O
When is encoder resolution specified in bits, and what does that tell us?
Absolute encoders — whether rotary or linear — track the position of an axis by assigning a unique value to each position on the encoder, so that no matter where the axis being measured is located, its exact position can be determined. And because each position is uniquely identified, this holds true even if the […]
What’s the difference between minimum incremental motion (MIM) and resolution?
When we talk about the positioning capabilities of a linear motion system, we typically talk about accuracy and repeatability, and in some applications — especially those driven by stepper motors — we may also be concerned with resolution. But accuracy and repeatability define a system’s ability to reach its commanded position and to do so over […]
What are the differences between incremental and sine-cosine encoders?
Encoders that provide incremental position measurements (whether rotary or linear) output two signals, or channels, typically termed “A” and “B,” to provide position and direction information. These output signals can be in the form of analog sine and cosine waves or in the form of digital square waves. Those that produce digital output signals are typically […]
THK OMNIedge System provides predictive failure detection of linear motion components
THK’s innovative OMNIedge System enables predictive failure detection of linear motion components for improved productivity and reduced maintenance costs. The OMNIedge network sets up automatically and sensors are simply installed on existing components for convenient and easy remote monitoring of operating conditions. Data is securely collected through a dedicated closed IoT network for analysis and […]
What is a linear variable differential transformer (LVDT)?
In previous articles, we’ve covered a variety of technologies for measuring linear position: magnetic and optical encoders, magnetostrictive sensors, and even measuring systems integrated into linear guide systems. Another technology for measuring absolute linear position is the linear variable differential transformer (LVDT). A linear variable differential transformer is an induction-based measuring system that consists of […]
NewTek sensor addresses requirements for custom LVDT position sensors
As many industries continue to experience supply chain challenges, NewTek Sensor Solution is addressing more requests for custom LVDT sensors in short timelines in meeting unique and demanding position measurement requirements for applications in a range of industries including oil/gas, packaging, manufacturing and power generation. As travel bans, border closures and regulations associated with COVID-19 […]
AutomationDirect adds inductive linear position transducers
Linear Variable Inductance Transducers (LVITs) from Alliance Sensors Group convert the linear displacement of an object into a proportional electrical signal output of 0 to 10 V or 4 to 20 mA (depending on model). LVITs are contactless devices designed for dimension or position measuring applications where the sensing element cannot be attached to the […]
Balluff’s new magnetic encoders easily integrate with Siemens motion control systems
Balluff’s new absolute magnetic linear encoders with Siemens Drive-Cliq interface are designed to integrate perfectly into Siemens motion controller environments. Plug-and-play installation makes incorporating them into the drive system easy. The controller automatically detects the sensor and its basic settings. Its automatic status monitoring continuously checks the measurement quality, detecting any mechanical position shift during […]
New linear measurement solution offers programmable option
Encoder Products Company’s (EPC) new addition to their line of linear measurement solutions offers users a spring-loaded mounting bracket combined with a choice of measuring wheel. They then select the encoder to meet their exact application requirements. With up to 10 lb of adjustable spring tension, this spring-loaded mounting bracket fits 2.5-in. shafted encoders with […]
