Flying lead temperature sensor | NTC 3 Kohm | metal probe | 1 m
Product description
The FLTSN-N is a stable passive temperature probe that measures ambient temperature using an NTC (Negative Temperature Coefficient) thermistor. This NTC 3 kΩ sensor element has a negative temperature coefficient, meaning its resistance decreases as the temperature rises. It also offers a fast response time of less than 1 second in liquids.
The platinum sensor element is resin-encapsulated inside a 53 x 8 mm stainless steel tube, ensuring long-term stability. The probe includes an integrated 1-meter long, extendable cable. This unshielded, 2-pole twisted cable (2 x 0.5 mm²) has alloy lead wires to ensure low thermal conductivity.
With a robust construction and precise measurement capabilities, this probe operates within a temperature range of -20°C to 60°C and a relative humidity below 95% rH (non-condensing), making it ideal for a wide range of applications.
Additional specifications and description
How Does This Temperature Probe Work, and What is NTC?
This temperature probe measures ambient temperature via a platinum element (NTC). This sensor element has an electrical resistance of 3 Kohms at 25 °C. It has a negative temperature coefficient. This means that the resistance decreases when the ambient temperature rises. Any device with an input for 'NTC passive temperature sensors' can read out the measured temperature.
What are NTC Thermistors, and Why are They So Important in HVAC Systems?
NTC thermistor probes measure temperature in various industries - from automotive, through green energy to domestic appliances, and even though their applications are endless, they are indispensable for HVAC.
The NTC thermistors increase or decrease their resistive value as the operating temperature around them fluctuates. They are extensively utilized as temperature sensors across a broad spectrum of equipment and systems, making them the preferred choice in virtually all applications where temperature monitoring is essential.
NTC thermistors are characterized by a negative resistance-temperature relationship. Their negative response enables them to exhibit significant variations in electrical resistance with even minor fluctuations in temperature. This property makes them well-suited for precise temperature monitoring and control application.

How is the Sensor Cable Extended, and How Does Length Affect Measurement?
This temperature sensor has an integrated cable. This unshielded 2-wire cable has a length of 1 m. The wires have a cross section of 0,5 mm². If necessary, this cable can be extended. The longer the cable length, the higher the influence of the resistance of the cable on the measurement readout. This sensor doesn't require a separate power supply.
What are the Temperature Probe's Integration and Protection Ratings?
Sentera’s thermistor probe is a negative temperature coefficient (NTC) thermistor chip, encapsulated in epoxy and potted in a steel tube housing with two wire leads. The stainless steel tube (53 x 8 mm) offers an IP65 protection degree against ingress of dirt and water.
