February 19, 2019 - NewTek Sensor Solutions expanded the capabilities of its DC LVDT technology with 4-20mA output capabilities to meet the needs of industrial monitoring and feedback applications. In addition to offering 4-20 mA versions of its free-core and spring-loaded LVDTs, the company customizes 4-20mA position sensors to customer specifications.
The 4-20 mA loop-powered LVDTs are designed for use in liquid level gaging, robotic automation and industrial automation controls. The 4-20mA output signal provided by the sensors integrates with a variety of PLCs, digital indicators, computer-based data processors, and QC data collection systems.
NewTek offers hermetically-sealed versions of its 4-20 mA free-core and spring-loaded LVDTs capable of withstanding dirt, water, steam and other harsh elements. 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.
The 4-20 mA sensors offer high resolutions with a standard 0.25% and optional 0.1% maximum non-linearity .
Operating from 11 –28 VDC, the DC-operated linear position sensors are available in full ranges from 0.10” (2.5 mm) to 20” (500 mm). NewTek offers its 4-20mA output sensors with built-in surge and polarity protection to guard against voltage spikes and hookup errors.
