Explosion-proof rated Ex/MBS Series miniature bearing sensors
The bearings of rotating equipment operate in arduous conditions, and the seals in typical sensors can break down over time, leading to oil leaking and wicking. This results in the potential for oil to ignite and catastrophic failure to occur at the junction box and surrounding area.
Conax Technologies’ Ex/MBS Series explosion-proof rated miniature bearing sensors are your NEVER-FAIL solution. Specially designed to excel in harsh environments where typical miniature bearing sensors fall short, these sensors utilize a proprietary redundant sealing process that eliminates the risk of oil leaking and wicking. Our Ex/MBS Series sensors have received the most stringent certifications, assuring they’re safe in explosive atmospheres. View a demo here.
Upstream: Exploration, Extraction and R&D
- Conax Down-Hole Semi-Rigid Cable Compression Seal Fitting—When installing long tubes, cables or items with connectors attached down hole, it’s inconvenient or impossible to feed these long-length items through fitting holes. Split fittings are a problem solver, because with the tight-toleranced internals removed, you can easily lower items down-well, then assemble the seal around the tubes/cables right where needed.
- Hazardous Location (HL) Compression Seal Fitting—Conax Technologies’ HL Compression Seal Fittings are designed for protection in a wide variety of hazardous environments. The Conax HL Fitting is pressure rated to 500 PSIg and has been CSA® certified in the U.S. and Canada for use in hazardous locations defined by the NEC® as Class I, Div. 1 and 2, Groups B, C, and D; Class II, Div. 1 and 2, Groups E, F, and G; and Class III.
- High Density (HD) Feedthroughs—Conax Technologies’ HD Series high density mechanically sealed feedthrough assemblies allow multiple insulated wires to be installed through a single port. These assemblies consist of a stainless steel tube swaged over bundled 24 AWG solid Teflon-insulated thermocouple wire or copper wires. The thermocouple pairs are available with or without junctions. HD assemblies provide an excellent means to pass numerous thermocouple, RTD and low voltage instrumentation wires through a vessel wall without breaching the wall in multiple locations.
- Multi-Hole Metal (MHM) Compression Seal Fittings—Conax MHM fittings can be customized to accommodate special hole patterns, irregular shapes and high density requirements. MHM fittings can be used to seal gradient thermocouple, RTD or thermistor probes, tube bundles, or a variety of devices within a single fitting. Our unique soft sealant technology seals against gases or liquids and resists element movement under pressure. Immersion lengths can be easily adjusted in the field. Individual elements can be set at different lengths to monitor multiple points.
- RTD & Thermocouple Assemblies for Hazardous Locations—Conax CBT 100, CBT 200, CBT 300 and CT 600 Series assemblies meet U.S. and Canadian standards (NRTL/C, CSA) for use in hazardous locations as defined by NEC Class 1, Division 1, Groups B, C and D; Class II, Groups E, F and G; and Class III.
- CBT 100 Series sensor-terminal head assemblies are available in all thermocouple calibrations and in RTD assemblies with 100, 200, 500 and 1000 ohm platinum, 10 ohm copper or 120 ohm nickel elements. Assemblies are available with stainless steel sheaths, a W8 mounting fitting and explosion-proof terminal head with terminal strip and 4-20mA transmitter.
- CBT 200 and CBT 300 assemblies are NEC-compliant replacement probes for use with UL and CSA-approved terminal heads in hazardous locations. CBT 200 provides a W8 fitting for attachment to the terminal head and to the vessel. CBT 300 provides a W7 fitting for attachment to the terminal head. A separate adjustable fitting is required to attach the probe to the vessel.
- CT 600 Series sensor-terminal head assemblies are available in all thermocouple calibrations and in RTD assemblies with 100, 200, 500 and 1000 ohm platinum, 10 ohm copper or 120 ohm nickel elements. Assemblies are available with stainless steel or Inconel sheaths, a spring-loaded mounting fitting (CSLW) and explosion-proof terminal head with terminal strip.
Downstream: Refining, Distribution and Storage
- Direct Immersion Grounded Junction Thermocouples—Conax Technologies has developed and tested a direct immersion, 1/8″ diameter grounded junction thermocouple design for operating pressures to 40,000 PSIg. Units have been proof pressure tested to 60,000 PSIg at room temperature. This design uses an economical proprietary method of silver brazing a high pressure fitting directly to the thermocouple sheath. Testing concluded that the thermocouple’s calibration (Type J Thermocouple) was maintained after silver brazing and pressure testing.
- Sample Probe Assemblies—Conax Technologies’ Sample Probe Assembly (SPA) is used to insert and retract an analyzer sample probe or injection quill into a pressurized process through a process isolation valve. Ideal for unique applications such as process analyzing, flare stack emissions, or hot tapping liquid or gas streams.
- Temperature Sensors with Thermowells—Thermowells are pressure-tight receptacles that extend the life of a temperature sensor in environments where the sensor is not chemically compatible with the process media or the sensor does not have the mechanical strength to withstand the process flow or pressure. Thermowells also facilitate removing, changing, checking or replacing sensors without draining the process system. The use of standardized thermowells throughout a plant permits easy relocation of sensors.
