Siemens QAE2120.010 Immersion & QAM2120.040 Duct Temperature Sensor Lot
Ni1000 temperature sensors for HVAC immersion and duct-mounted applications — priced per lot
Overview
This lot bundles a Siemens QAE2120.010 immersion temperature sensor with a QAM2120.040 duct temperature sensor, both using LG-Ni1000 sensing elements for reliable, accurate temperature measurement in HVAC systems. The QAE2120.010 is designed for immersion into pipes or vessels, complete with a stainless steel protection pocket rated PN10, while the QAM2120.040 is a duct-mounted probe with a 400mm capillary/probe length for airflow temperature sensing. This item may have broken or missing parts — please review the provided photos carefully, as the listing reflects the item's exact condition. Priced and sold as one complete lot.
Key Features
- Immersion sensor with protection pocket: QAE2120.010 includes a stainless steel PN10-rated protection pocket for durable, serviceable installation in liquid or steam applications.
- Wide immersion temperature range: Measures -30°C to 130°C with ±1.3K accuracy across the full range.
- Duct-mounted probe: QAM2120.040 offers a 400mm probe length for airflow temperature sensing, measuring -50°C to 80°C with ±1.8K accuracy.
- Reliable Ni1000 sensing element: Both sensors use the LG-Ni1000 element, known for stable, repeatable temperature measurement.
- Threaded connection: QAE2120.010 uses a standard G ½" connecting thread for straightforward pipe/vessel installation.
- Screw terminal wiring: Simplifies electrical connection and maintenance for the immersion sensor.
