Product pages on DRIVEKNMS are designed to verify model, brand and series first, then move the buyer into one clean quotation path.
Technical Dossier
The R. STAHL 9182 Series is a family of intrinsically safe temperature transmitters engineered for deployment in Zone 1 and Zone 2 hazardous areas under ATEX and IECEx certification frameworks. These devices are installed across global heavy industry sectors including petrochemical refineries, offshore oil & gas platforms, nuclear auxiliary systems, and large-scale chemical processing plants. The 9182 series converts thermocouple (TC) and resistance temperature detector (RTD) signals into standardized 4–20 mA analog outputs, providing galvanic isolation and EMC-compliant signal conditioning for DCS and SCADA integration. Their compact DIN rail form factor and wide ambient temperature tolerance (−40 °C to +70 °C) make them a standard specification item in EPC contractor bills of materials for hazardous-area instrumentation projects worldwide.
The following SKUs represent verified models within the R. STAHL 9182 series, classified by input type and output configuration. Each entry reflects a distinct ordering code used in EPC and MRO procurement.

9182/20-55-11: Wide-range TC input (B/R/S types), 4–20 mA, high-temperature process applications.
9182/20-56-11: Millivolt input variant, 4–20 mA output, for non-standard sensor types.
9182/20-57-11: Potentiometer/resistance input, 4–20 mA, position and level transmitter interface.
9182/20-58-11: Universal input (RTD/TC/mV/Ω), HART, SIL 2, full-featured flagship variant.
The 9182 series presents specific quality verification requirements due to its intrinsic safety certification dependencies and analog signal chain precision. DriveKNMS applies the following test protocol to all 9182 units processed through its facility: (1) Visual inspection of terminal blocks, housing integrity, and label legibility against R. STAHL factory standards. (2) Insulation resistance test between input, output, and power supply circuits to verify galvanic isolation integrity (minimum 100 MΩ at 500 VDC). (3) Functional loop test: application of calibrated RTD simulation (Pt100 decade box) and TC millivolt source across the full input range; output current verified at 4.00 mA (0%), 12.00 mA (50%), and 20.00 mA (100%) with ±0.05 mA tolerance. (4) HART communication verification (where applicable): connection to HART communicator to confirm device descriptor, PV mapping, and alarm configuration registers. (5) Ambient temperature soak test at −20 °C and +60 °C to verify output stability across operating range. All test data is logged and available to customers upon request as a unit-level certificate of conformance.
