Specialty and Support Sensors for Comprehensive Building Automation

From differential pressure sensors that help improve HVAC performance to IAQ monitors that support healthier environments, Honeywell's specialty and support sensors deliver precise data to help make the most of building automation systems. Our sensors integrate with existing building management system (BMS) platforms via Modbus, BACnet and Sylk protocols to help provide the continuous feedback needed to make informed, data-driven decisions that help improve both efficiency and comfort.

Precision environmental and HVAC sensors

Temperature, humidity and pressure sensing form the foundation of effective HVAC control. Honeywell's commercial building sensors offer precise, efficient solutions for a variety of needs.

Sensors work with HVAC controllers and direct digital controllers with multiple mounting configurations including wall, duct and outdoor options
Differential pressure sensors include the DPTE series for filter monitoring, DPT for clean rooms, and 629 series with 0.5% accuracy and NEMA 4X construction¹
Our sensors are built for reliable performance and ease of installation, with options to cover indoor and outdoor control applications

IAQ monitoring for healthier building environments

Supporting IAQ starts with precise detection. Honeywell's IAQ sensors provide continuous measurements to help facilities support healthier environments for their occupants.

TR50 series sensors monitor temperature, relative humidity, CO2, particulate matter (PM1.0, PM2.5, PM10) and total volatile organic compounds in one device
Customizable displays and thresholds are designed for stable long-term accuracy
Multi-sensors track PM2.5/PM10, CO2, TVOC, temperature and humidity simultaneously over RS-485 communication

BMS integration and scalable deployment

Sensor deployment shouldn't require extensive downtime. Honeywell's sensors are designed for smooth integration and scalable implementation with legacy BMS platforms.

Comprehensive protocol support (Modbus, BACnet, Sylk) provides connectivity to a wide range of existing BMS platforms
Split-core designs and tool-free mounting can enable installation without disconnecting power or extensive retrofit work
Field-configurable parameters help standardize hardware while adapting to site-specific requirements

Operational efficiency and predictive maintenance support

Unplanned equipment failures can drive up costs and disrupt operations. Honeywell's monitoring sensors help support predictive strategies that can help improve uptime across multiple systems.

Current sensors can facilitate early fault detection on motors, pumps and fans before failures occur
Load trending with 4-20 mA or 0-5/10 VDC outputs helps identify performance degradation and energy waste
Differential pressure monitoring can help improve maintenance intervals based on actual conditions

Application-specific sensors for specialized building needs

Many building applications demand specialized sensing beyond standard HVAC parameters. Honeywell's commercial building sensors help address a wide range of specific monitoring requirements.

Dew point sensors monitor cooling water pipes and chilled surfaces to help prevent condensation damage
Economizer sensors integrate with Honeywell's JADE economizer control to help improve free cooling and reduce energy consumption

Frequently Asked Questions About Specialty and Support Sensors

Differential pressure sensors continuously monitor pressure drops across HVAC filters, fans and ductwork to provide early warning of maintenance needs. For equipment monitoring, pressure differentials can indicate bearing wear or belt slippage before failure. Honeywell’s 629 series transmitters can deliver 0.5% accuracy with 4-20 mA output signals that integrate with existing BMS platforms to trigger alerts at preset thresholds.1 This helps teams schedule filter changes based on actual loading rather than fixed calendars.

Honeywell's sensors are designed for flexible integration with industry-standard protocols. Sensors communicate via Modbus, BACnet MS/TP or Sylk bus, providing connectivity for most BMS platforms. The TR50 IAQ sensors offer all three protocol options in configurable models. For simpler installations, sensors with analog outputs (0-10 VDC or 4-20 mA) connect directly to universal controller inputs. Split-core current sensors can be installed without disconnecting power.

IAQ sensors can help provide the continuous monitoring data that supports WELL, LEED and other certification programs. Honeywell's multi-parameter IAQ sensors can monitor temperature, humidity, CO2, PM2.5/PM10 and TVOC simultaneously —core parameters tracked by healthy building standards. Customizable displays can show air quality status to occupants, while integration with Honeywell's Healthy Buildings dashboards supports documentation and third-party verification in connection with certification requirements.
