LVDTs provide critical measurements for steam turbines
Hermetically-sealed linear position sensors from NewTek Sensor Solutions tolerate the high temperatures and vibrations of steam turbines to deliver accurate and reliable position feedback on the position of the governor and throttle valves. Their high measurement accuracy also makes them ideal for monitoring turbine shell expansion and bearing vibrations as part of process control systems. […]
LVDT position sensor operates in high-shock environments with up to 10K psi
NewTek recently designed its 100th custom LVDT position sensors with a vented body and modified lead lengths to address the unique operating specifications for a downhole drilling application. Venting NewTek’s NT-R high-temperature sensor ensured reliable performance in a downhole drilling tool that operated in a high-shock environment with pressures up to 10,000 psi and temperatures […]
NewTek LVDT position sensors serves as long-life replacements for failing potentiometers
NewTek Pre-calibrated Linear Position Sensors serve as long-term replacements for potentiometers (pots) that become unreliable over time due to their contacting operation and effects from vibration and other environmental parameters. As potentiometers rely on mechanical contact to provide position feedback, components wear out and are affected by heat, vibration, and humidity, making output progressively noisier […]
LVDT Position Sensors handle extreme pressures, high/low cryogenic temperatures
NewTek offers a customized version of its high-temperature LVDT position sensor for material testing in environments with extreme pressures and high/low cryogenic temperatures. Configured to operate in temperatures exceeding 1000°F (538°C), the NT-HT-1000 Linear Displacement Sensor is used for materials testing in autoclaves and material deformation testing in labs and nuclear applications. Available in configurations […]
LZ-19 Series LVIT linear position sensor
The LZ-19 Series of LVIT (Linear Variable Inductance Transducer) position sensors are contactless devices designed for use in factory automation or assembly machinery applications where space is a premium, as well as for external mounting on pneumatic cylinders to sense rod position. The LVIT is offered in nominal full scale ranges from 2.5 to 750 […]
Signal conditioner handles digital/analog comm for AC-LVDTs, RVDT, or LVRT half-bridge sensors
The NewTek NTC-6000 Qwik-Cal LVDT Signal Conditioner completes the measurement system for AC-operated LVDTs by providing the excitation and digital output required by many of today’s laboratory, industrial automation, and process control applications. Without internal electronics, AC-LVDTs can operate in extreme environments but require the NTC-6000 Signal Conditioner to convert position feedback into readable output […]
ICs for interfacing inductive sensors, Part 1
Designers who use inductive proximity sensors have a choice of high-performance signal-conditioning interface ICs, each offering different sets of features, functions, and capabilities. In the two preceding features (see Related EEWorld Content), we looked at the inductive proximity sensor and its basic operation but did not look at the electronic interface circuit for this widely […]
How is LVDT technology used for sensing?
Linear variable-differential transformer (LVDT) technology’s capability to accurately measure linear movement is used to provide a position to electrical output for pressure, acceleration and force measurements. For example, in a pressure sensor, the sensing element is a diaphragm that moves a rod or cylindrical core inside the coils of a differential transformer to change the […]
