Building Automation Products HVAC Sensors for Commercial and Industrial Building Systems

BAPI provides sensing and measurement products used in HVAC/R duct and room environments, including temperature, humidity, and pressure devices, along with related accessories and wireless test instruments. For LONG Building Technologies customers, these products are relevant when a building system requires practical sensing at the room, duct, surface, or pressure level, especially in facilities where control accuracy, physical installation conditions, or local operator interaction matter. LONG’s role is to help commercial and industrial facilities apply, engineer, integrate, and support these sensor-based building system components within larger HVAC and building automation environments.

BAPI Temperature, Humidity, and Pressure Sensors for HVAC Applications

BAPI’s product range centers on room and duct sensing, pressure measurement, and supporting accessories used in building systems.

Room sensing options include several temperature-focused devices for spaces where enclosure style matters. These include low-profile room sensors, wipedown room sensors, and models with local display and adjustment functions. Available configurations include temperature-only sensing, combined temperature and humidity sensing, setpoint adjustment, occupancy override, and optional fan speed control on specific models.

The line also includes surface-mounted temperature sensors intended for flat surfaces and areas that are harder to reach with more conventional probe styles. For duct applications, BAPI offers humidity sensors with optional temperature measurement.

Products on the pressure side include differential pressure sensors, adjustable pressure switches, outside pressure pickup ports, and duct total pressure probes. Together, these support pressure monitoring, airflow-related measurement, and pressure pickup in duct and outside-air applications.

BAPI also supplies test instruments used for temperature, humidity, and differential pressure measurement, as well as downloadable technical materials such as submittal sheets, pricing datasheets, installation documents, videos, application notes, catalogs, and service bulletins.

HVAC Sensor Applications for Duct, Room, and Pressure Monitoring

BAPI products are used in HVAC/R room and duct environments across a defined set of applications and facility conditions.

Environments include operating rooms, clean rooms, and elder care facilities where wipedown-compatible room sensing is relevant. Fan coil, heat pump, and unit ventilator applications for room devices provide local indication and user-adjustable functions.

Additional listed applications include industrial cooling-air circuits, ventilation ducts, and outside-air pressure measurement points mounted on rooftops, walls, soffits, or ceilings. Surface temperature sensing is also identified for windows, doors, solar panel modules, and other flat or difficult-to-access mounting locations.

Where these applications intersect with LONG’s work, LONG supports commercial and industrial facilities by applying and integrating sensing devices into broader HVAC and building systems, then supporting those systems over time through lifecycle service and technical support.

HVAC Use Cases for Room Sensing, Duct Monitoring, and Pressure Control

These products are relevant when a project or facility needs one or more of the following functions:

• Room sensing in areas that need surfaces suitable for regular cleaning
• Temperature sensing in visible interior spaces where a lower-profile appearance is preferred
• Discreet room temperature measurement using a paintable sensor footprint
• Surface temperature monitoring on flat surfaces or locations that are difficult to instrument with other sensor styles
• Duct humidity measurement, with the option to include temperature in the same sensing point
• Local display of room conditions with setpoint adjustment, occupancy override, and optional fan speed adjustment on supported models
• Monitoring of overpressure, vacuum, or differential pressure
• Air filter and fan status monitoring
• Airflow proving for heater control and frost prevention circuits
• Total pressure pickup in moving air within ducts when paired with zone pressure sensing
• Reduction of wind-related fluctuation at outside-air pressure pickup points

These are application-driven use cases drawn from the provided manufacturer inputs only. If a project requires integration into a broader BAS strategy or long-term support planning, LONG can help evaluate fit, apply the devices appropriately, and support implementation within the building system context.

Why Work With LONG

LONG Building Technologies supports commercial and industrial facilities as a technical partner for complex building environments. In the context of BAPI products, LONG’s role is not limited to supplying individual components. LONG helps apply these sensing products within HVAC and building systems, supports engineering decisions around where and how they fit, integrates them into the broader system where applicable, and provides lifecycle service and long-term support.

That matters most in projects where sensor selection affects control strategy, room conditions, duct monitoring, or differential pressure measurement across multiple system components. When product details, integration requirements, or application fit are unclear, contacting LONG is an appropriate next step for technical review and project-specific guidance.

About BAPI Sensors for Building Automation

BAPI is a manufacturer focused on HVAC/R sensing products used in room and duct applications, with product coverage across temperature, humidity, pressure, air quality, wireless devices, and test instruments.

Certain room models are built for wipe-clean spaces and include field-adjustable settings and local display features. Other room sensors are designed for lower-visibility installation where appearance is a consideration. Duct humidity products include features such as sealed probe installation details, mounting provisions, stated accuracy, and warranty coverage. The Modbus room sensor includes local display and user-adjustment functions. The pressure sensor inputs also identify selectable ranges and outputs, enclosure ratings, line-of-sight troubleshooting indicators, and optional NIST documentation on one referenced model. In addition, pressure accessories are noted for wind-stabilized outside-air pickup and configurable field adjustment on pressure switch products.
