Neptronic SHS80 Humidistat
The Neptronic SHS80 is a high-limit duct humidistat engineered for precise humidity control in commercial and industrial HVACR applications. This duct-mounted humidity sensor operates on a 24VAC supply and provides a 0-10 VDC output signal for continuous monitoring or a dry contact for high-limit safety shut-off. Designed to prevent condensation within ductwork, the SHS80 features a fast-response capacitive sensor element that ensures rapid detection of high-humidity conditions. Its adjustable setpoint range and narrow differential make it an essential component for safeguarding downstream equipment and maintaining air quality standards. The rugged NEMA 1 (IP20) enclosure protects internal electronics while the stainless steel probe ensures long-term stability in high-velocity airflow. When integrated into a building automation system (BAS), this electronic humidistat delivers the reliability required for critical humidity management, ensuring the system operates within safe saturation parameters to prevent mold growth and structural damage.
Key Benefits for Contractors- High-limit safety integration: Provides reliable 24VAC output to interrupt humidifier operation when duct humidity exceeds the setpoint.
- Precision sensing technology: Utilizes a high-quality capacitive element for accurate RH monitoring with minimal drift.
- Field-adjustable settings: Allows technicians to calibrate the trip point directly on-site to match specific HVAC system requirements.
- Streamlined installation: The compact probe design and standard terminal block simplify wiring for HVAC control upgrades.
Where is the best location to install a high-limit humidistat?
The SHS80 should be installed at least 3 meters (10 feet) downstream from the humidifier steam manifold or atomizing nozzle to allow for proper moisture absorption and prevent false tripping.
Can the SHS80 be used as a primary controller?
While it provides a 0-10 VDC signal, its primary function in most mechanical plant rooms is as a safety high-limit to prevent over-saturation in the supply duct.
How do I verify the 24VAC output functionality?
Technicians should check for continuity across the dry contacts or verify the output voltage at the signal terminals when the measured humidity exceeds the manual setpoint dial.
