Industrial Process Temperature Sensing Solution – BASF Catalysts EHK15-TW1 | 91090028 F977-R-10″
Where This Product Is Used
The BASF Catalysts EHK15-TW1 Thermocouple Probe (P/N 91090028, cross-references: 802-0051-00 / 502-0051-01 / 602-0051) is engineered for demanding temperature measurement in high-temperature, chemically aggressive industrial environments. Typical deployment scenarios include:
- Catalytic reactor beds – continuous monitoring of exothermic reaction zones in petrochemical and refining processes
- Chemical process vessels – precise temperature profiling inside reactors, autoclaves, and distillation columns
- Emissions control systems – SCR (Selective Catalytic Reduction) and oxidation catalyst units requiring stable, long-life probes
- Polymer & specialty chemical plants – polymerization reactors where temperature uniformity is critical to product quality
- Pharmaceutical manufacturing – validated temperature measurement in GMP-regulated process equipment
- Power generation – boiler and heat exchanger monitoring in utility and co-generation facilities

Application-Specific FAQ
Q: Is the EHK15-TW1 a Type K or Type J thermocouple?
A: The EHK15 designation indicates a Type K (Chromel-Alumel) thermocouple element, suitable for temperatures up to approximately 1260 °C in oxidizing atmospheres. Please confirm with your process datasheet before installation.
Q: Can this probe replace 802-0051-00 directly?
A: Yes. P/Ns 802-0051-00, 502-0051-01, and 602-0051 are all cross-references to the same physical assembly (91090028 / F977-R-10″). Verify thermowell bore diameter and insertion length before installation.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For out-of-stock situations, typical lead time is 2–4 weeks. Contact us for real-time availability.
Q: Do you provide calibration certificates?
A: Calibration certificates from the OEM or a third-party NIST-traceable lab can be arranged upon request at additional cost.
Q: Is this part RoHS compliant?
A: BASF Catalysts components are manufactured for industrial process use. RoHS compliance documentation can be requested – contact our technical team for the latest compliance declaration.
