ELEKTROPLAST MEHI49 Mechanical Hygrostat 86.49

The ELEKTROPLAST MEHI49 mechanical hygrostat is a precision-engineered device designed to monitor and regulate relative humidity levels within electrical enclosures, control cabinets, and various industrial environments. By continuously tracking moisture levels, this hygrostat ensures that connected heating or ventilation equipment activates automatically to prevent the formation of condensation and the subsequent risk of corrosion on sensitive electronic components. Its robust mechanical design provides reliable performance in demanding technical installations where maintaining a stable climate is critical for equipment longevity.

Advantages

The primary benefit of the MEHI49 hygrostat is its ability to provide autonomous climate control without the need for complex digital programming or external power sources for the sensing mechanism. Its durable construction ensures long-term operational stability in harsh industrial settings, effectively protecting expensive hardware from moisture-related damage. The device is straightforward to install and integrate into existing electrical systems, offering a cost-effective solution for maintaining optimal humidity levels and preventing electrical faults caused by dampness.

Suitable for

• Electrical control cabinets and switchgear enclosures
• Industrial automation systems
• Outdoor technical installations requiring moisture protection
• Telecommunications equipment housing

This device may not be suitable for environments with extreme temperature fluctuations that exceed the operating range of the mechanical sensor or in locations where high levels of corrosive gases or dust could interfere with the mechanical movement of the internal components. It is also not intended for use in residential HVAC systems or high-precision laboratory environments requiring digital accuracy.

Key specifications

• Type: Mechanical hygrostat
• Function: Humidity control and condensation prevention
• Application: Electrical enclosures and industrial cabinets
• Operating principle: Mechanical sensing element

To use the ELEKTROPLAST MEHI49, mount the device onto a standard DIN rail within the enclosure. Connect the hygrostat in series with the heating or ventilation equipment you wish to control. Once installed, adjust the setpoint dial to the desired relative humidity level. The device will then automatically switch the connected equipment on or off based on the ambient humidity detected inside the cabinet.

What to consider before purchase

• Verify that the enclosure size is compatible with the device dimensions
• Ensure the humidity range meets your specific environmental requirements
• Check that the electrical load of the connected equipment is within the device's switching capacity

For optimal performance, ensure the hygrostat is placed in an area with good air circulation, away from direct heat sources or air inlets that could cause false humidity readings. Regularly inspect the device during routine maintenance to ensure the mechanical sensor remains free of dust and debris.
