✅ Product Overview

The Siemens QAE2120.010 is a passive immersion temperature sensor designed for accurate measurement of water temperatures in pipes, tanks, and heating systems. Featuring a 100 mm LG-Ni1000 sensing element, it delivers stable and linear temperature readings, making it a superior alternative to traditional NTC thermistors.

🔧 Key Specifications:

• Sensing Element: LG-Ni1000 – highly accurate with a linear resistance response

• Immersion Length: 100 mm

• Temperature Range: -30°C to +130°C

• Accuracy: ±1.3 K (typical ±0.5°C for Ni1000)

• Time Constant: 30 sec (with pocket), 8 sec (without)

• Protection Pocket: Stainless steel, PN10 rated

• Connection: Screw terminals with G ½” thread

⚙️ Ideal Applications:

• Flow temperature control in HVAC and BMS systems

• Return temperature limiting in industrial processes

• Domestic Hot Water (DHW) temperature management

• Suitable for both air and water measurement environments

🆚 Why Choose Ni1000 Over NTC or PT Sensors?

• Ni1000 vs. NTC Thermistors: More accurate and linear, ideal for precision control

• Ni1000 vs. PT100/PT1000: More cost-effective while offering sufficient accuracy for most HVAC applications
