A hygrostat—specifically the Rittal Hygrostat—is a compact, precision humidity control device designed to monitor and regulate the relative humidity within electrical enclosures. Its main purpose is to prevent condensation and moisture build-up, both of which can cause corrosion, short circuits, and damage to sensitive electronics and control equipment.
How Does a Rittal Hygrostat Work?
The Rittal Hygrostat constantly measures the relative humidity inside an enclosure. When humidity rises above a user-set threshold (typically adjustable between 50% and 100% RH), the device automatically activates a connected heater or fan. By switching on these devices, the hygrostat reduces the relative humidity level and keeps it safely below the dew point, eliminating the risk of condensation on assemblies or electronic components.
Features and Benefits
- Reliable Humidity Response: Ensures that the enclosure environment never reaches damaging moisture levels.
- Flexible Mounting: Suitable for DIN rail, enclosure frame, or mounting plate installation.
- Wide Voltage Range: Operates on 24–250 VAC or 24–48 VDC, offering installation flexibility for different applications.
- Easy Integration: Terminal strip or screw connection for rapid wiring.
- Precise Control: User-adjustable humidity setpoint (commonly 50–100%), with fast switching to activate climate control equipment promptly.
- Compact Size: Fits neatly inside even small control cabinets.
Why Use a Rittal Hygrostat in Electrical Enclosures?
Electrical panels, particularly those installed in environments with temperature fluctuations or high humidity, are vulnerable to condensation—a factor that can silently degrade performance and reliability over time. By actively monitoring and responding to humidity changes, the Rittal Hygrostat helps:
