Frequently Asked Questions
Q: What heating systems is this brass thermistor 10K3435 probe compatible with?
A: This 10K NTC thermistor probe is designed for wall-mounted boilers, tankless water heaters, and central heating systems that require a 10K 3435 NTC temperature sensor. Always verify your system's sensor specifications before purchasing to ensure compatibility.
Q: What does the 10K3435 specification mean for this temperature sensor?
A: The "10K" refers to the thermistor's resistance value of 10,000 ohms (10 kΩ) at 25°C, and "3435" is the B-value (beta coefficient) that describes how resistance changes with temperature. Together, these values define the sensor's temperature-response curve, making it a precise and predictable replacement for OEM boiler sensors with the same rating.
Q: Why is brass used for the probe housing?
A: Brass is chosen for its excellent thermal conductivity, which allows the sensor to respond quickly to water temperature changes, as well as its strong resistance to corrosion in wet heating environments. This makes it a durable, long-life choice for boiler and water heater applications.
Q: Can I purchase multiple probes in one order?
A: Yes! This listing is available in packs of 1, 2, or 3 probes. Buying a multi-pack is a great way to have spare sensors on hand for future maintenance or replacements.
