10K Precision Metal Head Thermistor - 3950 NTC

Waterproof Stainless Steel Probe: Encapsulated in a corrosion-resistant metal cylinder housing to enable immersion temperature sensing in liquids, soil, or high-humidity environments.

Standard 3950 NTC Thermistor Curve: Utilizes a high-precision 10kΩ NTC thermistor element with a 3950 B-value constant for accurate, predictable temperature-to-resistance calculations.

High Thermal Conductivity: Heavy-duty metal head casing ensures fast heat transfer and rapid thermal equilibrium response times.

Durable Lead Cable: Features flexible insulated lead wiring for simple routing through conduits, enclosures, and liquid reservoirs.

Broad Measurement Range: Accurately measures temperatures across a wide range from -20°C to +105°C, making it ideal for fluid heating and cooling monitoring.

Housing Material: Stainless steel metallic probe head with PVC-insulated flexible lead wire.

Technical Specifications:

Sensor Type: NTC Thermistor (3950 Beta Value).

Nominal Resistance (R_25): 10 kΩ -+ 1% at +25°C.

B-Value: 3950K -+ 1%.

Probe Dimensions: Stainless steel cylinder head (5 mm x 25 mm approx.).

Operating Temperature Range: -20°C – +105°C.

Color: Metallic Silver Probe Head with Black Lead Cable.

Usage Advice: Connect in series with a fixed 10 kΩ pull-up resistor to form a voltage divider into standard microcontroller ADC pins; apply standard Steinhart-Hart or B-parameter code formulas.

Maintenance: Ensure the stainless steel probe tip remains free of heavy scale or chemical buildup; avoid exposing the non-waterproof cable wire joints to continuous liquid immersion.

Essential Liquid & Immersion Thermal Probe: Position as the go-to waterproof thermal sensing probe for aquariums, water heaters, solar thermal collectors, HVAC ducting, and 3D printer hotbed applications.

Highlight Stainless Steel Durability: Emphasize how the sealed metal head provides rugged protection against physical wear and direct fluid exposure compared to bare epoxy thermistor beads.

Recommended Cross-Sell Add-ons: Pair with 10K Ohm NTC Thermistor (5mm), 3PIN NTC Thermistor Temperature Sensor Module, 5V Temperature Sensitive Relay Module, and ESD antistatic mat 50x40CM PCB Welding Mat.
