NTC030HF01 - Carel PT100 NTC SENSOR China Original Manufacturer - เซ็นเซอร์อุณหภูมิ, สวิตช์ความร้อนและฟิวส์, ผู้จำหน่ายเทอร์โมสตัท

The Carel NTC030HF01 is an NTC temperature sensor for HVAC/R (เครื่องทำความร้อน, 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.

พูดง่ายๆ, it’s a “โพรบอุณหภูมิ” 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
ยี่ห้อ	Carel
ประเภทสินค้า	Passive NTC Temperature Sensor，(RTD) พีที100, พีที1000
Temperature Sensing Element	กทช (Negative Temperature Coefficient Thermistor), 10 kΩ @ 25°C, ค่าเบต้า 3435，พีที100，พีที1000
ช่วงการวัด	-50 ถึง +90 องศาเซลเซียส (some sources mention up to +105 °C in air)
Installation Method	Strap-on type for securing the sensor to the pipe surface
ความยาวสายเคเบิล	3 เมตร (flat black cable)
การจัดอันดับการป้องกัน	IP67 (dustproof and briefly submersible)
การเชื่อมต่อ	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, ท่อน้ำ, 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. ดังนั้น, please refer to the sensor parameters in this reply when making references.

คำแนะนำในการคัดเลือก:

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, ฮันนี่เวลล์, ฯลฯ), you can also do so, but you must ensure that the controller is compatible with the NTC 10k sensor; มิฉะนั้น, the readings will be inaccurate. For pipe temperature measurement scenarios, the clamp-on design of this sensor is very convenient for installation; อย่างไรก็ตาม, 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.
