Q1: What is the Siemens QAE2174.015?
It is an active immersion temperature sensor for measuring water temperature in pipes and tanks. It provides a 4…20 mA output proportional to temperature over a factory-set range of -10…120 °C .
Q2: Does this sensor support AC supply?
No. The QAE2174 series is DC-only (DC 13.5…35 V). For AC/DC supply, the QAE2164 series must be used .
Q3: What is the output signal?
The output is 4…20 mA, linear with temperature, with a maximum load of 500 Ω .
Q4: What is the measuring range?
The factory setting is -10…120 °C. Internal jumpers allow selection of 0…100 °C or 0…70 °C .
Q5: What is the sensing element?
It uses a Pt 1000 Class B element per DIN EN 60 751 .
Q6: Is a thermowell included?
No. The protective sleeve/thermowell is not included and must be ordered separately. The nominal pressure depends on the thermowell used: PN 10 with the standard brass thermowell, PN 16 with the stainless steel variant, or PN 16 with the AQE2102 clamping nipple .
Q7: What is the immersion length?
The immersion length is 150 mm .
Q6: What is the process connection?
The process connection is G ½" .
Q9: What is the protection class?
The sensor is rated IP54 per EN 60529 .
Q10: What is the ambient temperature range?
The operating ambient temperature range is -40…+70 °C .
Q11: What is the net weight and country of origin?
Net weight is 0.149 kg. Country of origin is China .
Q12: What should I verify before ordering?
Always verify the exact part number (QAE2174.015 for 150 mm, DC-only), confirm your control system provides DC 24 V (not AC), ensure the required thermowell or clamping nipple is ordered separately, and check that the 4…20 mA signal is compatible with your controller’s analog input.
