• Maximum measurable humidity 93% supporting high-moisture environments
• Wind detection up to 67 mph allowing robust wind monitoring
• Accepts 16/32V DC supply for flexible low-voltage integration
• Complies with EN 50428 providing adherence to standardised requirements
• Compact footprint 108 x 227 x 121mm for space-constrained sites
• Maximum measurable humidity 93% supporting high-moisture environments
• Wind detection up to 67 mph allowing robust wind monitoring
• Accepts 16/32V DC supply for flexible low-voltage integration
• Complies with EN 50428 providing adherence to standardised requirements
• Compact footprint 108 x 227 x 121mm for space-constrained sites
Applications
• Suitable for building automation ventilation control systems
• Ideal for outdoor weather-dependent process control loops
• Used with HVAC units for humidity and wind-triggered responses
• Can be used for site environmental monitoring in substations
• Suitable for integration into industrial data-acquisition racks

What power options are available for installation?
It operates from a DC supply selectable between 16V and 32V to match common low-voltage control supplies.
What environmental extremes can it detect reliably?
The unit captures relative humidity up to 93% and wind speeds as high as 67 mph, making it suitable for corrosive or exposed outdoor conditions where elevated moisture and strong winds occur.
How does the sensor suit space-limited panels?
Its Compact rectangular form with external dimensions 108 x 227 x 121mm permits mounting in constrained enclosures or on slim mounting plates.
Which industries can adopt its measurement characteristics?
Fields requiring discrete humidity resolution and wind assessment—utilities, automation, and mechanical plant monitoring—can utilise its measurement capabilities.
