Pipe and Tank Mounting (HANI)

When direct immersion is impractical, surface-mounted temperature measurement becomes a practical way to monitor process conditions without cutting into the line or vessel. Pipe and Tank Mounting (HANI) sensors are built for this role, helping engineering and maintenance teams capture temperature on pipe and tank surfaces while keeping installation simpler and less invasive than many in-line alternatives.

In process plants, OEM systems, utilities, sanitary production lines, and general industrial environments, this style of sensor is often used where fast deployment, serviceability, and repeatable mounting matter. The HANI range shown here focuses on clamp and bolt-on designs for pipes and tanks, with analog 4 to 20 mA output, making integration into PLC, BMS, SCADA, and other control systems more straightforward.

Designed for pipe and tank surface temperature monitoring

HANI sensors in this category are intended for applications where the process medium is typically water or water-based fluids, but the measurement is taken from the outside of the pipe or tank. This approach is useful when the process cannot be interrupted, when hygienic constraints limit intrusive fittings, or when retrofitting a temperature point onto existing equipment.

Compared with conventional insertion methods, a surface-mounted temperature sensor can reduce installation complexity and support maintenance access. It is especially relevant in skids, distribution loops, utility piping, washdown areas, and compact equipment where space, cleanliness, or process continuity are part of the design requirement.

Key mounting styles in this category

The products listed here cover several mounting formats within the HANI family. Clamp-mounted versions are available for plastic and metal pipes, while a bolt-on version is available for metal tanks. This makes the category suitable for a range of line materials and installation standards, from general industrial piping to more sanitary process environments.

For example, OMEGA models such as HANI-C-1.0I-P-MA and HANI-C-2.0I-P-MA are intended for industrial plastic pipe applications. For metal piping in industrial settings, models like HANI-C-2.0I-M-MA and HANI-C-4.0I-M-MA provide another fit. Where hygiene and cleanability are important, sanitary metal pipe clamp models such as HANI-C-2.0S-M-MA or HANI-C-4.0S-M-MA are aligned with food, medical, and pharmaceutical use cases.

Where these HANI sensors are typically used

The application scope in this category is broad. Industrial plastic pipe versions are relevant to HVAC, building services, clean water systems, fluid control, energy distribution, laboratories, and general manufacturing. Metal pipe and tank-mounted versions extend into chemicals, fuel and gas, oils, waste handling, and process utility systems.

Sanitary variants are particularly relevant where product safety, cleaning procedures, and external mounting convenience all matter. Food and beverage processing, pharmaceutical loops, and certain medical systems can benefit from a clamp-on temperature measurement approach that avoids direct contact with the process stream while still delivering a standard analog output for control and monitoring.

Selection factors that matter in real projects

Choosing the right model starts with the installation surface. Pipe material is one of the first checkpoints, since this category includes versions for plastic pipe, metal pipe, and metal tanks. Pipe size or tank geometry also matters because the listed models are sized for different maximum diameters, from smaller pipe runs up to larger process lines and compact tanks.

Next, consider response behavior, expected accuracy, and the environment around the sensor. Several models in this category offer accuracy down to ±0.5 °C, while some plastic-pipe models are specified at ±1.5 °C. Response time also varies, with some sanitary and metal-pipe units offering faster thermal response than plastic-pipe versions. For many buyers, the right choice is not simply the highest stated performance, but the best match between mounting surface, process conditions, and control requirements.

Electrical integration is another practical factor. These HANI sensors use 4 to 20 mA output and operate from 8 to 28 Vdc, which fits well into common industrial instrumentation loops. IP65 enclosure protection and M12 electrical connection details also support use in demanding field environments where moisture, routine cleaning, or mechanical handling are part of normal operation.

Representative products in the range

A few examples help show how the category is structured. The OMEGA HANI-B-TANK-M-MA is intended for metal tank mounting and can suit compact vessels in process and utility systems. For industrial metal pipe installations, HANI-C-3.0I-M-MA and HANI-C-2.5I-M-MA illustrate options for larger pipe sizes while maintaining the same general output philosophy.

On the sanitary side, HANI-C-1.5S-M-MA, HANI-C-2.5S-M-MA, and HANI-C-3.0S-M-MA reflect the availability of multiple pipe-size options for cleaner process environments. Buyers looking across the broader OMEGA product range can also compare these sensors with other temperature measurement formats when a project calls for different mounting or sensing methods.

How this category fits into a wider temperature sensing strategy

Pipe and tank mounting devices are often selected as part of a broader instrumentation scheme rather than in isolation. In some systems, they may be used for non-invasive trending, secondary verification points, or retrofit monitoring, while insertion probes or other sensor styles handle primary control tasks. That is why understanding the full measurement context is important before standardizing on one approach.

If your application requires alternative sensor constructions, it may also be useful to review related options such as C-type temperature sensors, D-type temperature sensors, or G-type temperature sensors. Each format serves different mounting, thermal contact, and installation preferences, so comparison can help narrow the right fit for the application.

Practical buying guidance

Before ordering, it helps to confirm five points: mounting surface material, line or tank size, expected temperature range, required signal interface, and the operating environment around the sensor. In this category, the listed products are generally intended for process temperatures up to 100 °C, with use on water and water-based fluids, so these should be checked against the actual service conditions.

It is also worth considering whether calibration in the installed condition is part of your maintenance practice. Some models note that improved accuracy may be possible with one-point or two-point in-situation calibration. For systems where external temperature reading is used for process consistency, energy monitoring, or quality support, that can be a meaningful advantage.

Conclusion

Pipe and Tank Mounting (HANI) sensors provide a focused solution for external temperature measurement on plastic pipes, metal pipes, and metal tanks. With clamp and bolt-on mounting styles, IP65 protection, and loop-powered 4 to 20 mA output, this category is well suited to industrial, sanitary, and utility applications where straightforward installation and reliable signal integration are priorities.

By matching the sensor to the pipe or tank material, size, and application environment, buyers can choose a model that supports both practical installation and useful process visibility. For teams building or upgrading temperature monitoring points, this category offers a clear starting place within the broader temperature sensor portfolio.
