About BAPI – Building Automation Products, Inc.

Building Automation Products, Inc. (BAPI) has been a trusted name in HVAC/R sensing since its founding in 1993. What began as a small operation in Cross Plains, Wisconsin has grown into a globally recognized manufacturer headquartered in Gays Mills, Wisconsin, with a manufacturing facility in Poland and regional sales offices spanning Canada, the United Kingdom, Australia, and the United Arab Emirates. For over three decades, BAPI has built its reputation on one guiding principle: that accurate, reliable sensing is the backbone of any effective building automation system.

A Comprehensive Sensor Lineup

BAPI specializes in sensors and transmitters designed specifically for heating, ventilation, air conditioning, and refrigeration applications. Their product portfolio spans temperature, relative humidity, pressure, wireless, CO2, and VOC sensors, as well as test instruments, Electronics Technician Assistants (ETA), and a full range of accessories. Whether the application calls for a discreet room sensor, a rugged duct unit, an outdoor air sensor, or a specialty immersion probe, BAPI offers a solution engineered for that precise environment.

Among their most well-regarded product lines are their HVAC Temperature Sensors — a diverse family that includes room, duct, averaging, immersion, clamp, strap, and extreme-temperature variants. Patented designs like the BAPI-Stat "Quantum" and "Quantum Prime" deliver large, easy-to-read displays along with wipedown capability for demanding environments such as operating rooms and clean rooms. For aesthetics-conscious installations, low-profile "Button" sensors and Decora Style units blend seamlessly into any décor without sacrificing measurement accuracy.

What Sets BAPI Apart

BAPI's commitment to quality is embedded at every stage of production. Every manufacturing station uses computer-aided build documents, schematics, and 3D renderings to ensure each unit is built to engineering specifications. Select temperature, humidity, and pressure sensor models carry CE certification, and all manufacturing adheres to RoHS-compliant, environmentally responsible practices.

Where BAPI truly distinguishes itself from the competition is with its industry-leading warranty program. Most sensor manufacturers simply replace defective products — BAPI goes further. Their "BAPI-Backed" guarantee means that if a product fails within the warranty period, they will repair or replace it and provide a product credit to offset any incurred costs. A lifetime limited warranty is also available on many of their single-point, room, and non-room temperature sensors — a level of confidence rarely seen in the sensing industry.

Built for Building Automation Professionals

Hospitals, clean rooms, data centers, laboratories, commercial offices, and refrigeration facilities all depend on sensors that are not just accurate, but fully compatible with their building automation systems (BAS). BAPI's sensors are engineered for 100% compatibility, outputting industry-standard signals such as 4–20mA, 0–5V, 0–10V, thermistor curves, and RTD formats. Their wireless sensor system supports up to 28 sensors and is compatible with BACnet IP, BACnet MS/TP, and Modbus RTU protocols — giving facility managers and HVAC engineers the flexibility to expand and integrate without rewiring.

For professionals who demand precision and durability from their sensing equipment, BAPI continues to set the benchmark in building automation sensor technology.
