Accessories, Spare Parts & Consumables

One partner for every installed part.

What It Is & How It Works

Cognesense is the single partner for OEM spare parts, accessories, consumables, and upgrade hardware across the installed base of every heritage capability including Varec, L&J Technologies, Shand & Jurs, Shand & Jurs Biogas, Sonitus Systems, Pyroban, Pyropress, Petrel, Ex-tech, and ExSolutions.

Each installed unit carries a unique configuration: model and revision, tag number, hazardous location class, soft-good material, and factory calibration. Spares and accessories are matched against the engineering record on file rather than selected from a generic catalog. That is what keeps performance, certification, and approvals valid through the maintenance cycle, and what protects the safety of your installation.

Provide the tag, serial number, or original purchase order, and we identify OEM spares, accessories, and upgrade options for your equipment, including connectivity upgrades, board-level retrofits, mechanical part replacements, and soft goods for installed vents and tank protections equipment. For aging assets with incomplete documentation, our service team can identify parts from nameplate data, site survey photos, or a field visit.

Varec: Spare parts and upgrades for gauge boards, float-and-tape gauges and transimtters, 8810/9810 RTUs, FuelsManager®, and TacFuels® components.
L&J Technologies: Electronics boards, wireless upgrades, components, and retrofit adapters for gauges, transmitters, temperature probes, switches, and alarms.
Pyropress: Diaphragms, microswitches, transmitter modules, and valve internals for installed Ex d, Ex ia, and industrial pressure/temperature instruments.
Petrel: Lamps, LED modules, drivers, lenses, gaskets, and brackets for installed ATEX and IECEx hazardous-area lighting and signaling fixtures.
Shand & Jurs: Insulation jackets, swing joints, soft goods, pallets, screens, and gaskets for installed vents, arresters, valves, and gauge hatches.

Environmental Monitoring & Hazardous-Area Compliance

Sonitus Systems: Microphone cartridges, calibration accessories, mounting hardware, and dashboard upgrades for installed noise, dust, vibration, and air quality stations.
Pyroban: Gas detection sensors, conversion-kit consumables, and certification renewals for Ex-protected vehicles, engines, GSE, HVAC, and stationary systems.
Ex-tech: Glands, gaskets, viewing windows, terminal blocks, and components for Ex enclosures, control cabinets, junction boxes, motor starters, and switches.
ExSolutions: Compliance services rather than parts: ignition hazard assessments, ATEX and IECEx design reviews, training, and audit support for aftermarket work.

Why It Excels

Configurations Matched to Your Installed Unit

Parts sourced against the tag, serial, or purchase order on the engineering record — not against a generic part number.

Certifications Preserved

ATEX, IECEx, OIML R85, custody-transfer, and overfill-prevention approvals remain valid because the replacement part carries the same engineering record as the original.

Modernization Without Replacement

Board upgrades, protocol changes, and retrofit hardware extend installed assets without removing them from service or rewiring your site.

One Partner Across Every Heritage Capability

Cognesense supplies parts for every brand in the portfolio through one channel, with the original engineering records on file and the compliance services to verify aftermarket work.
