HVAC Sensors - Refrigeration and HVAC

Marine HVAC and refrigeration sensors monitor temperature, pressure, humidity, airflow, water leakage, and refrigerant conditions in accommodation, machinery spaces, provision rooms, and cargo areas. They provide inputs for control, alarm, and protective shutdown systems.

ProShipWorks provides end-to-end support to source and supply HVAC Sensors for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification	Applicable requirements may include IEC 60092 for electrical installations in ships, IEC 60533 for electromagnetic compatibility, and IEC 61326 for measurement and control equipment. Exact compliance depends on sensor type, installation, and manufacturer declaration.
Class Approval	Marine type approval is model- and application-dependent. DNV, ABS, Lloyd's Register, Bureau Veritas, and ClassNK may approve selected sensor products or the complete HVAC/refrigeration system. Verify the certificate for the specified model and vessel installation.

Installation, Maintenance & Safety Information

Installation Notes	Install at the manufacturer-specified sensing location using suitable marine-rated cable glands, brackets, and wiring. Observe polarity, sensor range, controller input type, and shielding requirements. Pressure sensors require compatible fittings and leak testing.
Maintenance Tips	Inspect wiring, connectors, mounting, and cable glands during planned maintenance. Check temperature, humidity, pressure, and differential-pressure readings against calibrated reference instruments. Replace damaged, corroded, contaminated, or drifted sensors.
Safety Notes	Isolate electrical power before wiring or replacement. Depressurize and recover refrigerant before removing pressure sensors or fittings. Use approved refrigerant procedures and personal protective equipment. Do not bypass sensor alarms or compressor safety controls.
