NewTek Sensor Solutions offers its hermetically sealed position sensors with a 4-20mA current loop output that has become the data transmission standard in the process control industry.

Offering rugged operations and high performance with low power consumption, Newtek’s HI Series of hermetically sealed 4-20 mA LVDTs ensure highly reliable and consistent data output for factory automation, materials testing and packaging equipment applications. Requiring less power than similar DC-operated LVDTs and signal conditioners, these 4-20mA sensors also satisfy low power budgets. 

Sustaining accuracy with no errors over long distance transmissions, the 4-20mA current does not degrade over long connections and is less sensitive to background electrical noise. Simple to connect and configure, the 4-20mA output position sensors offer plug and play compatibility with most PLCs and controllers. Units also require less wiring and connections than other signals to reduce startup costs. 

NewTek offers its hermetically sealed 4-20mA LVDTs with either a radially- or axially-mounted connector. Units are available in ranges of 0.1” (2.54mm) to 20” (500mm). In addition to being sealed to IP-68, windings of the HI series are potted inside the housing with a two-compound epoxy for maximum resistance against harsh environment conditions. Operating temperatures range from -15°F to 185F° (-25°C to 85°C).

NewTek hermetically-sealed 4-20mA position sensors are available for quick shipment.
