Thermokon AKF10+ PT100 300.06: robust temperature Sensor with extra-long measuring tube for HVAC and industry
The Thermokon AKF10+ PT100 300.06 is a versatile duct Sensor, immersion probe, and temperature Sensor in one. This Sensor is ideal for applications where deep and accurate temperature measurement is required, for example in large air ducts or tanks. The 300 mm long Sensor sheath made of high-quality stainless steel V4A (1.4571) offers excellent chemical resistance. All in all, this makes the Sensor extremely suitable for use in HVAC systems and industrial environments with aggressive media. In addition, the IP65 housing guarantees reliable operation under harsh conditions. On the other hand, the passive PT100 sensing element ensures simple, maintenance-free connection to existing control systems.

Frequently asked questions about the Thermokon AKF10+ PT100 300.06
Why choose a Sensor with a 300 mm length?
This length is ideal for applications where a deep or central measurement is desired, for example in wide ducts or larger tanks.
Is this Sensor suitable for chemically aggressive media?
Yes, because the sheath is made of stainless steel V4A (1.4571), the Sensor is resistant to aggressive liquids, vapors, and gases.
How do I connect this Sensor?
You only need to connect the PT100 probe via screw terminals to a measuring or control system. External power supply is not required.
Is an immersion tube necessary?
Although not mandatory, an immersion tube such as the THMS or THVA ensures faster replacement, better protection, and a longer service life in liquid systems.
Can I use this Sensor outdoors?
Unlike standard sensors, this model is also suitable for outdoor use thanks to IP65, provided it is installed and shielded correctly.
