The FOXBORO FDC280 RH101FQ is a industrial-grade humidity and temperature transmitter designed for precise environmental monitoring in process control systems. It’s built to handle tough industrial conditions while delivering consistent, accurate data—something I’ve come to expect from FOXBORO’s instrumentation line. Personally, I found that this model stands out for its easy calibration process; unlike some transmitters that require specialized software, the FDC280 RH101FQ lets you tweak settings with a simple handheld tool, which saves a ton of time during on-site checks.
Le FOXBORO FDC280 RH101FQ est un transmetteur d’humidité et de température de gamme industrielle, conçu pour la surveillance précise de l’environnement dans les systèmes de contrôle de processus. Il résiste aux conditions industrielles difficiles tout en fournissant des données fiables et précises—un atout typique des instruments FOXBORO. Il se distingue également par sa facilité d’utilisation, même pour les équipes peu familiarisées avec les équipements de contrôle, grâce à une interface intuitive.

From my experience, the wide operating temperature range is a huge plus—we installed several of these in a chemical plant where temperatures swing drastically, and they’ve held up without any drift in readings. The ATEX certification also gave our safety team peace of mind, which is non-negotiable in hazardous areas.
Personally, the dual-protocol support was a game-changer for us. We have a mix of old HART-based controllers and new Modbus systems, and the FDC280 RH101FQ talked to both without any custom coding. That saved our IT team days of work.
If the FDC280 RH101FQ doesn’t fit your exact needs, these related models are worth checking out—all from FOXBORO’s FDC280 series, so they share the same reliable build quality:
L’installation du FOXBORO FDC280 RH101FQ est simple : les supports de montage muraux ou sur tuyau sont fournis, et le guide d’installation comprend des schémas clairs pour le câblage. Pour la maintenance, il est recommandé de vérifier la calibration每年一次 et de nettoyer le capteur avec un tissu sec (évitez les solvants agressifs). En cas de problème, le code d’erreur affiché sur l’interface HART aide à diagnostiquer rapidement la cause.
Installing the FDC280 RH101FQ is straightforward—all mounting brackets (wall and pipe) come in the box, and the wiring diagram is printed right on the unit’s cover, so you don’t have to fumble with a manual. I’ve walked through installations with our tech team, and the brackets line up perfectly with standard drill holes, cutting setup time to under 30 minutes per unit.
For maintenance, FOXBORO recommends annual calibration (using their handheld calibrator or a third-party tool) and occasional sensor cleaning with a dry cloth. Avoid harsh cleaners—we tried isopropyl alcohol once, and it didn’t damage the sensor, but the manual warns against it, so better to stick to dry wiping. The HART interface also lets you run diagnostic checks remotely, which means you don’t have to send someone to the field unless there’s a physical issue.
Le FOXBORO FDC280 RH101FQ bénéficie d’une garantie de 1 an à partir de la date d’achat, couvrant les défauts de fabrication et les pièces défectueuses. La garantie n’inclut pas les dommages causés par une installation incorrecte, un usage abusif ou des conditions hors spécifications. Pour demander une garantie, il faut présenter la facture d’achat et le numéro de série du produit.
FOXBORO backs the FDC280 RH101FQ with a 1-year standard warranty, covering manufacturing defects and faulty components. Having dealt with warranty claims before, their support team is responsive—we had one unit with a faulty analog output, and they shipped a replacement within 5 business days once we provided the serial number and proof of purchase.
Note that the warranty doesn’t cover damage from improper installation (like wrong voltage) or harsh chemicals beyond the unit’s specifications. We learned that the hard way once—someone used a solvent to clean a sensor, and it voided the warranty, so make sure your team follows the maintenance guidelines.
