ELSNER 70158 KNX W sl Wind sensor for KNX

The ELSNER 70158 wind sensor is a device designed for the KNX building bus system, specialized in measuring wind speed. This sensor is ideal for outdoor applications, thanks to its robustness and reliability even in extreme weather conditions.

Technical characteristics

The ELSNER 70158 wind sensor measures wind speed electronically, ensuring a silent and reliable measurement, even during hail, snow and sub-zero temperatures. The measurement also includes turbulent winds and anabatic winds in the vicinity of the weather station.

Wind Measurement

The wind speed is measured in the range of 0 to 35 m/s. If the wind measurement value does not vary by more than ± 0.5 m/s within 48 hours, an error message is generated with a maximum value of 35 m/s. All wind alarms with limit values below 35 m/s become active accordingly.

Threshold and Logic

Up to 3 threshold values are configurable for each parameter, both through communication objects and through local settings. The sensor also includes 8 AND logic gates and 8 OR logic gates.

Physical Characteristics

The sensor is made of plastic material, with a white or translucent color. The mounting can be done both on the wall and on the pole, thanks to the two included stainless steel installation bands.

• Dimensions: approximately 96 × 77 × 118 mm (W × H × D)
• Weight: about 170 g
• Degree of protection: IP 44
• Ambient temperature: Operating -30°C to +50°C, storage -30°C to +70°C

Food and Communication

The sensor is powered at 20-30 V DC, with a maximum consumption of 30 mA and 0.4 W. The connection is made via a KNX +/- bus terminal.

• Cable cross-section: massive conductors up to 1.5 mm² or conductors with fine wires
