NewTek Sensor Solutions now offers loop-powered 4 – 20 mA outputs on its free core, spring-loaded, hermetically sealed and custom LVDTs in providing a robust measurement signal for integration into a variety of PLCs, digital indicators, computer-based data processors and QC data collection systems. The 4-20mA Position Sensors can be used for industrial monitoring and feedback applications such as liquid level measurement, robotic automation, manufacturing processes and other industrial automation controls.
Key performances
The 4-20mA current is less sensitive to background noise and reduces voltage drops in analog voltage signals. As a result, users can run longer cable runs, such as those required in subsea applications, without the effects of EMO or noise on the signal. With the frictionless operation and better performance associated with LVDT technology, the 4-20 mA Displacement Sensors offers high resolutions with a standard 0.25% and optional 0.1% maximum non-linearity.
Robustness in all applications
Constructed of TIG welded stainless steel, these DC-operated Linear Position Sensors operate in hostile environments while the loop wiring connects to instrumentation remotely positioned in benign locations. Hermetically-sealed versions of 4-20 mA LVDTs are capable of withstanding dirt, water, steam and other harsh elements.
NewTek 4-20mA output sensors are designed with built-in surge and polarity protection to guard against voltage spikes and hookup errors. The domestic sensor manufacturer also customizes its 4-20mA Position Sensors with high stroke to length ratios, corrosion-resistant materials, extreme temperature parameters, custom signal conditioning and more to meet the requirements of nearly every application.
