HV Series Overview
The HV Series is built on Superior Sensor’s NimbleSense architecture, engineered for the measurement conditions that define commercial HVAC: low-pressure differentials in high-noise environments and long-term accuracy requirements that span months or years between calibrations. While most HVAC pressure sensors are adapted from industrial designs, the HV Series was purpose-built with multi-order digital filtering to suppress fan and blower noise, a stability specification measured in pascals, and Multi-Range technology that covers the full breadth of HVAC applications in a single device.
Multi-Range technology
A single HV Series device supports up to eight configurable pressure ranges, from the tens of pascals needed for air quality monitoring to the several kilopascals required for VAV control and filter monitoring. One part number replaces the sensor variants that would otherwise require separate selection, stocking, and qualification for each HVAC pressure range.
Advanced Digital Filtering
Fan cycling and blower operation generate pressure noise that contaminates low-pressure HVAC measurements at the signal level, where air quality and filter monitoring operate. The HV Series multi-order digital filter removes this noise before it reaches the measurement output, producing readings that reflect actual system conditions rather than the HVAC equipment’s acoustic signature.
Long-term stability
HVAC sensors in installed systems must maintain accuracy between commissioning cycles, which can span months or years without recalibration. The HV Series specifies long-term stability in pascals, ensuring that detection thresholds for filter blockage, duct pressure deviation, and VAV performance remain valid throughout the full service interval.
Integrated 50/60 Hz notch filter
HVAC environments concentrate electrical interference from motors, compressors, and variable-frequency drives at 50 and 60 Hz, the same frequency range in which low-level pressure signals operate. The HV Series integrated notch filter eliminates this interference at the measurement front end, preventing electrical noise from appearing as pressure variation in applications where the real signal is only a few pascals above the noise floor.

HV Series Benefits Summary
HV Series Frequently Asked Questions
How many pressure ranges does the HV Series support in a single device, and how are they selected?
The HV Series supports up to eight configurable pressure ranges in a single device, depending on the model. The active range is selected via the digital interface, allowing the same device to cover low-pressure air-quality applications at tens of pascals and higher-pressure VAV and filter-monitoring applications at several kilopascals without a hardware change. This eliminates the need to stock separate sensor variants for each HVAC pressure application.
What is the difference between the HV Series and the ND Series for low-pressure HVAC applications?
Both series share the NimbleSense architecture and Multi-Range technology but are optimized for different environments. The HV Series is temperature-compensated from 0°C to 50°C and includes digital filtering optimized for the fan and blower noise typical of commercial HVAC systems, with a 9-millisecond update rate suited to building automation. The ND Series is temperature-compensated from -20°C to 85°C and has a 2-millisecond update rate, making it the better choice for applications requiring faster response or wider temperature coverage, such as industrial environments.
How does the HV Series filter out fan and blower noise from real pressure measurements?
Fan cycling and blower operation create pressure fluctuations that appear at the sensor input along with the actual differential pressure being measured. The HV Series addresses this with two filtering mechanisms: a multi-order digital filter that removes broadband noise generated by fan operation, and an integrated 50/60 Hz notch filter that eliminates electrical interference from motors, compressors, and variable frequency drives. Together, these filters produce a clean pressure output that reflects actual system conditions rather than the noise environment of the HVAC equipment.
How is long-term stability specified for the HV Series, and what does it mean for a building automation system?
HV Series long-term stability is specified in pascals and as a percentage of full scale, measured after the first 12 months of operation. This means the sensor’s zero and span accuracy degrades by no more than a defined number of pascals over the monitoring period, regardless of the pressure range in use. For a building automation system, this means the sensor’s ability to detect filter blockage, duct pressure deviation, or VAV underperformance remains valid through a full annual service cycle without interim recalibration.
Does the HV Series work with the AZ100 auto-zero valve?
Yes. The AZ100 auto-zero valve is compatible with the HV Series and automatically zeros the sensor at configurable intervals, eliminating zero-point drift in installed HVAC systems where manual recalibration between commissioning cycles is impractical. The AZ100 is particularly useful in continuously operating building automation systems, where drift over time would otherwise degrade detection accuracy for filter monitoring and VAV control.
How do I choose between the HV110, HV120, HV160, and HV210 models?
The HV Series models differ primarily in their pressure range coverage and sensitivity. The HV210 covers the lowest pressure ranges, down to ±25 pascals, and is suited to air quality monitoring and high-sensitivity airflow applications. It also features position insensitivity, which is ideal for applications where the sensor’s orientation will change over time. Similar to the HV210, the HV110 covers low-to-mid pressure ranges and is suited to filter monitoring and air quality measurements. The HV120 and HV160 extend the range upward for VAV control and duct pressure monitoring. The HV160 supports up to eight pressure ranges, making it the most flexible model for designs that need to cover the full HVAC pressure range in a single device.
