Marine environments combine seawater corrosion, vibration, shock, and humidity in ways that destroy conventional sensors. Thermometrics selects materials and constructions specifically for marine service: titanium sheaths for seawater immersion, Inconel for engine exhaust, and explosion-proof heads for hazardous zones.
Exhaust gas temperature, cooling water, lube oil, and bearing temperature sensors for main and auxiliary diesel and gas engines. MIMS Type K assemblies with Inconel sheath for exhaust service. Pt100 RTDs for water-cooled systems.
Titanium-sheathed RTDs for seawater cooling systems. Titanium Grade 2 and Grade 4 resist pitting corrosion and stress-corrosion cracking from warm seawater that degrades 316SS and even duplex grades in some environments.
Explosion-proof thermocouple and RTD assemblies for ATEX Zone 1 and Zone 2 (IECEx) offshore platform applications. Corrosion-resistant Hastelloy and Duplex 2205 sheath materials. Weatherproof connection heads with dual-conduit entries.
High-pressure thermowell-mounted sensors for marine boilers and steam distribution. Flanged thermowell systems rated to ANSI 900# and 1500#. Duplex element configurations for redundancy in critical monitoring points.
Flush-mount and multi-point tank temperature sensors for LNG carriers, chemical tankers, and crude oil tankers. MIMS multi-point assemblies provide temperature profiles at multiple depths within a single tank nozzle.
MIMS construction provides inherent vibration resistance that conventional wire-in-tube sensors lack. For high-vibration applications such as engine room installation, MIMS sheath OD and attachment method are selected to avoid resonance.
