New P-Series LVDTs are Suitable for Use in Harsh Ocean Environments

Press Release Summary:

NewTek’s P-Series of High-Pressure and Water Resistant LVDTs are suitable for reliable position measurements in deep subsea environments and high-pressure applications such as pressure test vessels and hydraulic actuators. Constructed of 0.52 in. diameter heavy-duty alloy, units can be operated at temperatures up to -65° to 400°F and pressures up to 20,000 psi. The sensor provide ratiometric output with range of ±22.86 mm and linearity of < ± 0.15% full range.

High-Pressure and Seawater-Resistant Position Sensors from NewTek Perform In Deep Subsea and Other Extreme High- Pressure Applications

Pennsauken, NJ, June 12, 2018…NewTek Sensor Solutions offers the P-Series of High-Pressure and Water Resistant LVDTs for highly reliable position measurement in deep subsea environments and other extreme high-pressure applications such as pressure test vessels and hydraulic actuators. These sensors serve as ideal replacements for load cells, pots and magnetostrictive sensors in underwater use.

While other position measurement technologies such as load cells and pots fail over time in deep subsea environments, these highly durable, AC-operated linear position sensors are constructed of special heavy-duty, high-pressure alloys to operate reliably at pressures up to 20,000 psi and operating temperatures of -65° to 400°F (-55° to 200°C). Absence of electronics also makes the P-Series of High-Pressure and Water-Resistant LVDTs ideal for long-term operation in harsh ocean environments, especially important for industries requiring long-term sensor performance to avoid expensive hardware replacement or maintenance. 

Other significant features of NewTek High-Pressure and Sea-Water Position Sensors include:

  • Thick 0.52 inch diameter housing constructed of special alloys avoids corrosion for long-term operation
  • Nominal range of +0.90” (+22.86 mm) and more
  • Ratiometric output for reduced thermal sensitivity
  • Excellent linearity of < ± 0.15% full range
  • High-cycle life
  • High sensitivity and resolution

In addition to AC-operated sensors, NewTek also offers DC- operated LVDTs for high pressure or subsea use. DC-LVDTs with 4-20 mA output can reduce noise vulnerability and transmit the signal over long runs of cable - often a critical requirement of subsea measurement applications.

NewTek offers the P-Series High-Pressure and Water-Resistant Linear Position Sensors in custom and standard sizes. The company accepts small- to large-sized orders and manufactures prototypes to spec. All products are USA-manufactured.
