Product Description

Product Overview

As a classic sensing device within the industrial automation portfolio, the QAE3174D.015 immersion temperature sensor is specifically engineered for precise liquid temperature monitoring. Boasting high stability and strong adaptability, it finds extensive application in industrial fluid control scenarios, serving as a core component for ensuring safe equipment operation and accurate process regulation.

Precise Temperature Monitoring
Employing a high-accuracy platinum resistance (Pt1000) sensing element, it covers a measurement range of -30°C to 130°C with Class A accuracy. This enables real-time capture of minute liquid temperature fluctuations, outputting a stable 4-20mA DC analogue signal. This ensures data transmission is free from delay or deviation, providing reliable temperature reference for control systems.
Robust Environmental Adaptability
The sensor probe, crafted from stainless steel (1.4571), exhibits exceptional corrosion resistance and impact resilience. It can be directly immersed in common industrial fluids such as water, oil, and ethylene glycol, accommodating pressure ranges from 0 to 10 bar. Even in humid or vibration-prone industrial environments, it maintains long-term stable operation with a service life exceeding 8 years.
Convenient Installation Design
Features a G1/2 threaded interface supporting vertical or horizontal immersion mounting, compatible with diverse pipe and vessel specifications. Sensor cable length defaults to 2 metres (customisable from 3 to 10 metres), utilising oil-resistant, ageing-resistant PVC sheathing. Requires no additional protection for complex installation environments, significantly reducing installation complexity.
Safety and Compliance Assurance
Complies with IEC 60751 international standards and EN 61326 industrial electromagnetic compatibility requirements, featuring robust electromagnetic interference (EMI) resistance for reliable operation in high-EMF environments (e.g., near frequency converters). Additionally certified to CE and UL standards, meeting global industrial market safety access requirements for multinational project applications.
