Typical Applications

For temperature measurement of fluids within pipelines or tanks
such as hydraulic oil, cooling water inlets/outlets, and heating circulation loops. These sensors screw directly into place, and the -200 to 500°C measurement range covers the vast majority of industrial fluid applications. Protective sheath diameters of 6mm or 8mm are available; the 8mm version is suitable for pressurized environments, withstanding pressures up to 200 bar.
For OEM equipment integration
such as temperature monitoring points within compressors, pump sets, and air conditioning units. The advantage of Hirschmann connectors is their ease of connection and disconnection; sensors can be replaced during field maintenance without rewiring, making them particularly practical when cabinet space is limited.
Why Choose our products ?
The core technology of the HNT20 lies in the integrated combination of a high-precision PT100 platinum resistance temperature detector (RTD) probe and signal conditioning circuitry, enabling accurate and stable industrial-grade temperature measurement.
Sensing Element: High precision and stability of the PT100 platinum RTD.
Accurately capturing, amplifying, and converting the resistance changes of the PT100 into a standard industrial signal constitutes the core technical function of the HNT20 as a transmitter.
All-Metal Integrated Packaging: The sensing element and circuitry are housed together within an all-stainless steel (304/316) probe and casing; an IP65 protection rating ensures airtight integrity and long-term reliability in harsh environments characterized by moisture or corrosion.
Key Advantages
Wide temperature measurement range: –200 °C to +500 °C; a single sensor covers applications from cryogenic to high-temperature conditions, offering flexible selection.
Standard analog output: 4–20 mA (500 Ω load) or 1–5 V; wide-range 12–30 V DC power supply; directly compatible with PLC/DCS systems.
Diverse probe specifications: Φ6 / Φ8 thermowells with pressure ratings of 40 / 100 / 200 bar; 304 / 316 stainless steel construction suitable for corrosive media.
Flexible mechanical connections: Imperial threads, metric threads, and sanitary clamp fittings; compatible with European and Asian standards; custom lengths available.
Rapid thermal response: τ₀.₅ < 5 s (typically 2.3 s); suitable for dynamic processes and fluctuating operating conditions.
Traceable accuracy: Class A / Class B platinum resistance elements; tolerances of ±(0.15+0.002|t|) °C or ±(0.30+0.005|t|) °C; compliant with IEC standards.
Compact and robust: All-stainless steel welded construction; IP65 protection rating; vibration and shock resistant; suitable for long-term industrial field installation.
