You can purchase H&B sensors and related instrumentation at competitive prices from our company. As a long-term partner with ABB, the company that acquired the original manufacturer of H&B products, we have the advantage of supplying both genuine legacy parts and modern, direct-replacement units. We can also assist with the selection and migration of these critical devices. A personal manager will explain the step-by-step process for purchasing H&B products.
“H&B” is a brand name that refers to Hartmann & Braun, a historic German manufacturer of process instrumentation and control systems. In 1999, Hartmann & Braun was acquired by Elsag Bailey and subsequently became part of ABB. While the original H&B brand is no longer in production, the legacy of its high-quality products continues, and ABB provides modern alternatives and support for installed H&B systems.
H&B Sensors Product Categories
While the original H&B product line is now considered legacy, the name is still strongly associated with a specific range of reliable sensors. Their main product categories include:
- Temperature Measurement: This is a core product line. H&B sensors are well-known for their RTD (Pt100, Pt1000) and thermocouple sensors. These were designed for rugged industrial applications and are still in use in many plants today.
- Level and Pressure Measurement: H&B also produced a range of level float switches and pressure transmitters, which are known for their simplicity and robustness.
- Controllers & Indicators: The original H&B product line included controllers and indicators used in process control loops, with brands like the Contronic series.
ABB’s Modern Replacements
For customers with legacy H&B systems, ABB provides a direct replacement path with their modern instrumentation lines, which offer enhanced features and performance.
- Temperature Transmitters: The new ABB portfolio, such as the TTH300 and TTR200 series, provides advanced features like digital communication (HART, FOUNDATION Fieldbus) and is often designed for seamless integration with legacy H&B wiring.
- Pressure & Level Transmitters: ABB’s 266 series of pressure and differential pressure transmitters can serve as a modern, high-accuracy replacement for H&B’s older transmitters.
- Control Systems: For legacy H&B control systems, such as the Contronic series, ABB offers upgrade and migration paths to their modern System 800xA distributed control system.
Key Features
H&B products were highly valued for the following characteristics:
- Robust and Reliable Design: H&B sensors were known for their rugged construction, which allowed them to withstand harsh industrial environments, including high temperatures and vibration.
- High Performance and Accuracy: The original products were leaders in their time for providing accurate and stable measurements in critical industrial processes.
- Long Service Life: The durability of H&B sensors means many are still in operation today, underscoring their quality and longevity.
To receive a commercial offer for the supply of an H&B sensor or its modern ABB replacement, please contact our specialists. To create a request, you’ll need to specify the product type (e.g., RTD sensor, pressure transmitter) and, if possible, the original part number or a detailed description of the application, including the media, required temperature/pressure range, and process connection details. Providing this detailed information is crucial to ensuring the product offered is the precise one for your needs.
