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.
