Certification Standard & Electrical Safety Performance

This certificate corresponds to the marking II 1G Ex ia IIC T4 Gb, belonging to Category 1 intrinsically safe equipment, applicable to Zone 0 permanent explosive gas environments. The sensing circuit is designed with limited voltage, limited current and limited energy structure to eliminate ignition risks caused by electric sparks or thermal effects under fault conditions. Built-in thermistor temperature compensation circuit will not produce energy overflow during operation. Each probe is inspected in batches against this certification standard before delivery, with calibration data traceable to NIST standards. The signal cable supports a maximum transmission distance of 610 m without breaking intrinsic safety characteristicsInstrumetr.... Operating temperature range: -20 ℃ ~ +60 ℃, safe working pressure up to 345 bar.

Structural & Environmental Adaptability

The probe body adopts sealed integral structure with 316 stainless steel / nickel alloy wetted parts, matched with sintered metal protective filter to prevent medium pollution while maintaining explosion-proof integrity. The overall structure passes anti-vibration and thermal cycle tests, IP66 protection grade, resisting damp, dust and weak corrosive gas interference in industrial sites. The threaded installation interface matches standard sampling loops, pressure regulators and filter assemblies without destroying intrinsic safety certification validity during field assembly.

Matched Equipment & Application Scenarios

Applicable sensing hardware: all M-series alumina probes including M21R, MS29, MS32, NC22, Ni2

Matching host equipment: MMS35, MTS6, HygroPro fixed moisture analyzers, PM880 portable dew point meter (must use certified intrinsic safety barriers for system matching)

Typical scenarios: natural gas pipeline dew point detection, power generator hydrogen cabinet monitoring, petrochemical process gas measurement, semiconductor high-purity gas, heat treatment protective gas monitoring. This certificate document is mandatory for equipment access, factory safety audit and project acceptance in European and domestic explosion-proof projects.

Stability & Maintenance Advantages

The intrinsic safety performance marked by BAS01ATEX1096X remains effective within the probe’s service life under standardized installation. Unified certification specifications reduce site safety verification workload during probe replacement. Original certified probes avoid hidden explosion hazards brought by unqualified generic sensors. Complete certification documents are delivered with goods for filing management. Shockproof sealed packaging protects probe safety during transportation and storage, and safety indicators keep stable in dry storage conditions.
