Seametrics PS98i Submersible Level Sensor

from $3.71
Transducer & Cable:

Brand: Seametrics

Designed for long-term deployment, the PS98i uses a media-isolated pressure sensing element with NIST-traceable calibration for reliable, repeatable measurements.

The Seametrics PS98i Submersible Pressure Transmitter is a rugged, high-performance solution for accurate liquid level and pressure measurement in water, wastewater, environmental, and industrial applications. Designed with an industry-standard 4–20 mA output, this submersible level sensor delivers reliable, stable readings even in electrically noisy or harsh field environments.

Engineered for long-term deployment, the PS98i features advanced noise immunity, transient protection, and thermal compensation, ensuring consistent measurement accuracy across varying temperatures and conditions. Its durable construction—combining 316 stainless steel, fluoropolymer, and PTFE materials—provides exceptional resistance to corrosion and environmental stress.

FEATURES

  • Industry-standard, 2-wire, 4-20 mA configuration

  • 316 Stainless Steel, Standard (Titanium Optional)

  • Gauge or Absolute Pressure (PSIG or PSIA)

  • ± 0.25% FSO typical accuracy

  • Operates on low power

  • 1/4 NPT end cone adapter option

  • Narrow 0.75″ diameter, 8″ length

  • Reverse polarity protection

Shipping Note: This product ships in approximately 7 - 10 business days.
