Temperature Sensor Rittal SK external for Blue e+ cooling units model 3124400

External temperature sensor Rittal SK for Blue e+ cooling units (model 3124400) is a compact sensing accessory designed to measure ambient temperature in HVAC and cabinet cooling applications. Intended for integration with Blue e+ refrigeration units, the sensor supplies accurate temperature data to the cooling controller to support precise regulation of cabinet environment and protection of installed electronic equipment.

Advantages

The Rittal SK external temperature sensor delivers reliable, repeatable temperature readings that help maintain stable conditions inside server racks and electrical enclosures. Its external mounting option enables measurement at a representative location within the cabinet or room, improving control loop performance of Blue e+ cooling units. The sensor’s compatibility with Rittal Blue e+ systems simplifies installation and commissioning and reduces the need for additional adapters or configuration.

Suitable for

• Temperature monitoring in server rooms and data cabinets
• Integration with Rittal Blue e+ cooling units for feedback control
• HVAC applications where accurate cabinet temperature measurement is needed
• Electrical enclosures and control cabinets requiring environmental protection

When it may not be suitable

This external sensor is intended specifically for use with Rittal Blue e+ cooling systems; it may not be compatible with non-Rittal controllers or generic HVAC systems without appropriate interface hardware. It is a temperature sensing device only and does not provide humidity, pressure, or airflow measurement. For applications requiring multi-parameter environmental monitoring, additional sensors will be necessary.

Key specifications

• Sensing function: ambient temperature measurement
• Designed for external mounting in cabinets or rooms to measure representative temperature
• Electrical interface: designed to connect to compatible Blue e+ cooling unit controllers
• Form factor: compact sensor housing suitable for cabinet installation
• Use environment: indoor electrical enclosures, server rooms, and HVAC cabinets

How to use

Mount the sensor at a representative location inside the cabinet or in the area to be monitored, avoiding direct exposure to cooling airflow or heat sources that could skew readings. Connect the sensor to the Blue e+ cooling unit controller following the manufacturer’s wiring guidelines and secure any cable runs to prevent damage. After connection, configure the cooling unit controller to use the external sensor input as the control or monitoring source and verify correct temperature reporting through the unit’s display or management interface.

What to consider before purchase

• Confirm compatibility with your specific Blue e+ cooling unit model and controller inputs
• Ensure mounting location will provide representative ambient temperature measurements
• Check required cable lengths and routing for your installation environment
• Determine whether additional environmental sensors (humidity, airflow) are needed for your application

Usage recommendations

For best results, position the Rittal SK external temperature sensor away from direct vents, heaters, and power-dissipating components so the measurement reflects the average cabinet temperature. Regularly inspect the mounting and cable integrity during maintenance intervals and validate readings against a calibrated thermometer when setting control thresholds.
