NTC030HF01 - Carel PT100 NTC SENSOR China Original Manufacturer - Capteur de température, interrupteur thermique et fusible, fournisseur de thermostats

The Carel NTC030HF01 is an NTC temperature sensor for HVAC/R (Chauffage, Ventilation, Air Conditioning, and Refrigeration) systems. It is manufactured in China by brands such as Siemens and Honeywell. Please refer to the drawings and parameters for the NTC030HF01.

En termes simples, it’s a “sonde de température” with a 3-meter cable. To help you quickly determine its suitability, I have summarized the core parameters as follows:

Main Features and Application Scenarios

Parameter Items	Detailed Information
Marque	Carel
Type de produit	Passive NTC Temperature Sensor，(RTD) PT100, PT1000
Temperature Sensing Element	CTN (Negative Temperature Coefficient Thermistor), 10 kΩ @ 25°C, Valeur bêta 3435，PT100，PT1000
Plage de mesure	-50 à +90 °C (some sources mention up to +105 °C in air)
Installation Method	Strap-on type for securing the sensor to the pipe surface
Longueur de câble	3 mètres (flat black cable)
Indice de protection	IP67 (dustproof and briefly submersible)
Connexion	Stripped ends, 2-core wire

The main feature of this sensor’s design is its clamp-on mounting design, making it ideal for measuring the temperature of the outer walls of pipes, such as refrigerant lines, conduites d'eau, or other pipes in HVAC systems.

Another advantage is its high IP67 protection rating, meaning it is effectively dustproof and waterproof, and can operate reliably in humid industrial environments, even those occasionally exposed to water.

One important information discrepancy to note:

There is a misleading piece of information in the search results: some websites incorrectly describe “NTC030HF01” as a PLC (Programmable Logic Controller). This is clearly an information entry error, as at least eight sources from different distributors consistently confirm that it is an NTC temperature sensor. Donc, please refer to the sensor parameters in this reply when making references.

Recommandations de sélection:

If you need to use it to upgrade or repair Carel equipment, you can simply replace it. If you want to use it with controllers from other brands (such as Siemens, Honeywell, etc.), you can also do so, but you must ensure that the controller is compatible with the NTC 10k sensor; sinon, the readings will be inaccurate. For pipe temperature measurement scenarios, the clamp-on design of this sensor is very convenient for installation; cependant, it is not the ideal choice for measuring air temperature.

If needed, I can guide you on how to test the quality of this sensor or help you find a compatible controller model.
