The PAROS 20-IMV-1 Shipboard Barometer from AMETEK Inc. - compact marine sensor built for rough seas

The PAROS 20-IMV-1 Shipboard Barometer from AMETEK Inc. sits bolted to a steel bulkhead, its anodized housing cold to the touch and humming quietly with the ship's vibration. On the bridge display, crew see clean pressure data instead of flickering analog needles.

Compact barometer for harsh decks

AMETEK's PAROS 20-IMV-1 Shipboard Barometer is a compact marine sensor designed to measure atmospheric pressure on commercial and research vessels with high stability and low noise. It targets navigation systems, automatic weather logging and safety alarms on board.

The unit is built around a solid-state pressure transducer and signal-conditioning electronics, factory calibrated to marine standards for long-term stability. According to AMETEK, the enclosure is IP-rated and corrosion-resistant to cope with salt spray and constant vibration.

What AMETEK promises

Product manager Michael Bartholomew at AMETEK emphasizes that the PAROS 20-IMV-1 is tuned for shipboard integration rather than lab benches. That means a wide operating temperature range, robust mounting options and electrical interfaces ready for typical bridge systems.

The barometer outputs digital signals compatible with standard marine data networks, which helps yards and integrators tie it into multifunction displays and logging software. AMETEK positions the PAROS 20-IMV-1 alongside its other PAROS-branded barometers used in meteorological and oceanographic applications.

Installation and daily handling

On board, technicians typically install the PAROS 20-IMV-1 near the ship's bridge or in an instrument room, away from direct spray but still close to reference air pressure. The compact footprint helps when bulkhead space is crowded with radios and navigation gear.

Cabling runs from the sensor to the ship's data concentrator or directly to navigation computers, where software logs the pressure trend in hectopascals. Officers see a steady graph, giving them time to react to sudden drops that may signal a storm front.

Where it fits in AMETEK's line-up

AMETEK integrates the PAROS 20-IMV-1 into a broader portfolio of marine and process instrumentation, including level transmitters, thermometers and other sensors for harsh environments. The company segments these products under its electronic instruments group.

For ship owners, the advantage is a single supplier that can cover multiple sensor points, simplify maintenance agreements and provide documentation from one source. That can be valuable when classification societies require rigorous calibration records.

Company context and shares

AMETEK, headquartered in Pennsylvania, positions itself as a global manufacturer of electronic instruments and electromechanical devices, serving aerospace, power, process and marine markets. The PAROS 20-IMV-1 sits in a niche, but it contributes to the recurring revenue from instrumentation and service contracts.

AMETEK shares (ISIN US0311001004) trade on the New York Stock Exchange in US dollars, where investors track the company's portfolio of specialist products as a driver of long-term growth.
