Brand: Seametrics

High-accuracy 4–20 mA level measurement with optional temperature output

The Seametrics PS9800 is a high-accuracy, submersible pressure transmitter for continuous water level and liquid pressure measurement. Its two-wire 4–20 mA output integrates directly with data loggers, PLCs, SCADA systems, process displays, and telemetry equipment.

Designed for long-term deployment in wells, tanks, surface water, wastewater, and environmental monitoring applications, the PS9800 combines ±0.1% full-scale accuracy with thermal compensation, electrical noise immunity, and built-in transient protection. Gauge and absolute pressure configurations are available, along with optional temperature measurement, titanium construction, and multiple submersible cable materials.

Key Features

  • ±0.1% full-scale pressure accuracy

  • Two-wire 4–20 mA pressure output

  • Optional temperature measurement

  • Gauge and absolute pressure configurations

  • 9–24 VDC low-power operation

  • Thermally compensated from 0–50°C

  • Built-in transient and reverse-polarity protection

  • Acetal and 316 stainless steel construction

  • Optional titanium construction

  • Polyurethane, polyethylene, or ETFE submersible cable

  • Slim 0.75-inch diameter for wells and narrow installations

  • Optional 1/4-inch NPT end-cone adapter

ORDERING GUIDE

How to Configure the Seametrics PS9800

Configure the PS9800 by selecting the pressure reference, measurement range, output, construction, cable material, and required cable length.

1

Select Gauge or Absolute Pressure

Gauge Pressure

Recommended for most continuous water-level applications. The vented cable compensates for changes in atmospheric pressure.

Absolute Pressure

Uses a sealed reference and does not require a vented cable. Barometric compensation may be required for accurate water-level calculations.

2

Select the Measurement Range

Choose a pressure range that exceeds the maximum expected water depth or operating pressure. Avoid selecting a range that is significantly higher than necessary, since a properly matched range provides better usable measurement resolution.

5 PSIG 12 ft H2O
15 PSIG 35 ft H2O
30 PSIG 69 ft H2O
50 PSIG 115 ft H2O
100 PSIG 231 ft H2O
300 PSIG 692 ft H2O

The ranges shown above are standard gauge-pressure configurations. Absolute-pressure configurations are also available.

3

Select the Measurement Output

Pressure Only

Provides a two-wire 4–20 mA output for continuous liquid-level or pressure measurement.

Pressure + Temperature

Adds an optional temperature measurement channel for applications that require both level and water-temperature data.

4

Select the Sensor Construction

Standard Construction

Acetal and 316 stainless steel construction for groundwater, surface water, tanks, and general water-level monitoring.

Optional Titanium

Select titanium when enhanced corrosion resistance is required for saltwater, brackish water, or chemically aggressive liquids.

5

Select the Cable Material

Polyurethane

A flexible, abrasion-resistant choice for most groundwater, surface-water, and general monitoring installations.

Polyethylene

Suitable when additional moisture resistance or compatibility with certain liquids is required.

ETFE

Provides enhanced chemical and temperature resistance for more demanding installations.

6

Specify the Cable Length

Select a cable length that reaches from the installed sensor to the termination point, data logger, control panel, or telemetry enclosure. Include additional length for routing, service loops, and future maintenance.

Avoid submerged cable splices. Whenever possible, use one continuous cable from the sensor to a dry and accessible termination point.
