Each application has unique thermal dynamic characteristics and the design of the probe assembly, both internal and external, is tailored to best meet the customer’s needs. Perhaps the most misunderstood parameter in temperature sensor design is the thermal response and/or thermal time constant. A sensor assembly that responds well in one application may not respond suitably in other applications. Littelfuse utilizes proprietary design and manufacturing methods to create temperature sensor assemblies that respond well to temperature changes affecting the principal sensing portion of the assembly, and at the same time are less influenced by thermal gradients affecting other areas of the sensor assembly or the lead wires connected to the temperature sensing assembly.
