Linear encoders are often essential. Even where they’re not, benefits they offer can justify the additional cost they incur. Linear encoders bypass the mechanical linkages of rotary-to-linear motion axes to directly measure positions of loads. That avoids the effect of backlash, pitch errors, vibration problems, and the way in which heat causes expansion and geometrical […]
Encoders + sensors (linear) + I/O
How some sensors use giant magnetoresistance
So, what if an application needs a sensor to track an axis 360° and beyond? Absolute encoders need a power source and (for some designs) can be prohibitively costly while potentiometers can lack sufficient resolution. So, for applications not satisfied by these other options, multiturn shaftless rotary sensors are a leading option. These multiturn sensors: […]
NewTek NTC-6000 adds digital outputs for legacy LVDTs
NewTek has released the NTC-6000 Qwik-Cal LVDT signal conditioner, which adds digital outputs to existing LVDT sensors. The unit lets facilities connect legacy LVDTs, RVDTs and LVRT half-bridge sensors to digital control systems, automation networks or IIoT platforms without replacing the sensors. Many analog sensors can be difficult to connect to modern control systems, and […]
Linear position sensors with signal conditioning
The TE1 Series of absolute linear position sensors from Novotechnik U.S. feature an integrated microprocessor and associated circuitry to provide signal conditioning for a current or voltage output signal. The signal conditioned output enables the TE1 Series to have long cable runs without substantial signal loss and can be connected directly to the analog input […]
High-accuracy position sensors unaffected by magnetic fields
Novotechnik U.S. has introduced the LS1 series of advanced inductive linear position sensors, with stroke lengths of these non-contact sensors from 25 to 200 mm. Absolute linearity of the LS1 Series is to ≤ 0.1 % of full scale with repeatability to < 3 µA or 3 mV, depending on current or voltage output selected. […]
Displacement sensors with integrated inclination sensor
ASM’s new posiwire sensors, the WST61, WST85 and WST21, combine linear position determination and inclination measurement, ensuring easy installation and cost-effectiveness. In many applications, such as telescopic crane booms, transport cranes, machines for the pharmaceutical industry and in medical technology, both linear position and inclination need to be determined. As a rule, two different sensors […]
Measuring wheels enable linear position and speed sensing with rotary encoders
POSITAL’s measuring wheels and accessories, combined with the company’s versatile IXARC encoders, can be a convenient and accurate way of measuring linear motion in applications such as conveyer systems or the manufacture of rolled products. Recent enhancements to POSITAL’s programmable encoders have made it simpler to configure wheel-equipped encoders to meet users’ exact requirements. “Encoders […]
Position sensors with 400 °F temperature range tolerate temperature spikes
NewTek Sensor Solutions offers several LVDTs with an extended 400 °F temperature range for use in applications where temperature spikes are possible. The high-temperature, ac-operated position transducers ensure reliable position measurement without failure in applications with fluctuating temperatures where standard-temperature sensors can fail, due to deteriorating insulation and intermittent connections. For example, standard-temperature position sensors […]
AMETEK offers reduced lead times for LDTs
AMETEK Factory Automation has further reduced the lead time for the 953A Linear Displacement Transducer (LDT). AMETEK is committed to streamline the production processes and optimizing supply chain management, and this has resulted in a substantial decrease in the time it takes to deliver this critical component to customers worldwide. The market for position sensors, […]
New linear position detector series from Nidec
Nidec Machine Tool Corporation will launch the MPLS series, an inductive coupling principle-type linear position detector that determines a machine’s position and detects its feed digitally, on November 1st. Intended for compact machine tools, it uses a signal-detection method and integrates numbers of substrates to realize a simple structure that does not require scale wiring […]
