Thermal actuator temperature sensing element (wax motor)
"HYSTERESIS" Hysteresis is the temperature differential between the graphed upstroke and down stroke of a wax motor as a result through heating and cooling. Hysteresis is caused by the thermal inertia of the element and by the friction between the parts in motion internally. An actuator's piston extends when it senses thermal increase and retracts when it is cooled. The temperature points when this occurs are not identical. The difference between the two points is called "hysteresis". Hysteresis is deliberate and will prevent unnecessary switching/modulation between temperatures that frequently fall above and below a set point.
