Precision temperature control starts with a precision temperature sensor. This is a ±1% thermistor that is 20 kΩ at 25°C.

Wavelength is transitioning to a small epoxy-coated bead head with a 2.4 mm maximum outer diameter for applications where embedding the thermistor is required. Old phenolic-backed stock will be depleted before shipping new epoxy-coated stock. The epoxy-coating ensures durability and protects against exposure to moisture, high and low pressure, and corrosive environments. It has solid nickel wires with Teflon® insulation to provide isolation when assembled in metal housings.

Dissipation Constant is ~1 mW / °C in still air.
Thermal Time Constant is ~1 second in stirred liquid.

It is ideal for sensing temperature when embedded in materials or small laser packages. A complete Resistance vs. Temperature chart is included in the datasheet. It is sold in packs of 10.

Free, effective, and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard product can be easily modified to meet your application requirements.

Wavelength Temperature Controllers include stable bias current sources of 10 µA and 100 µA. The following selection guide shows where the thermistor signal is within range of the controller inputs.
