A method of manufacturing an aerosol provision apparatus and an aerosol provision apparatus

An aerosol provision apparatus for heating smokable material to volatilize at least one component of the smokable material, the aerosol provision apparatus comprising:

• a heater arrangement for heating smokable material contained in use within the aerosol provision apparatus, the heater arrangement comprising at least a first heating zone and a second heating zone for heating different portions of the smokable material;
• and
• a temperature sensor for each of the first heating zone and the second heating zone, each temperature sensor for providing temperature measurements to be used as input temperature measurements for a respective temperature control loop, each temperature control loop for controlling the heater arrangement to heat the associated respective first heating zone or second heating zone to a target temperature based on the input temperature measurements acquired by the associated temperature sensor;
• wherein each temperature sensor is positioned in an associated heating zone at a selected position so that, if the heater arrangement were to heat the first heating zone and the second heating zone so that the temperature sensors measure the same pre-selected target temperature, a temperature gradient across length of the first heating zone and the second heating zone between the temperature sensors would be optimized as being substantially flat.

A method of manufacturing an aerosol provision apparatus for heating smokable material to volatilize at least one component of the smokable material, the method comprising:

• providing a heater arrangement for heating smokable material contained in use within the aerosol provision apparatus, the heater arrangement comprising at least a first heating zone and a second heating zone for heating different portions of the smokable material;
• providing a temperature sensor for each of the first heating zone and the second heating zone, each temperature sensor for providing temperature measurements to be used as input temperature measurements for a temperature control loop, the temperature control loop for controlling the heater arrangement to heat an associated respective heating zone to a target temperature based on the input temperature measurements acquired by the associated temperature sensor;
• and
• positioning each temperature sensor in the associated heating zone at a respective position selected so that the temperature sensor for the first heating zone is positioned to measure the temperature at a part of the first heating zone with which that temperature sensor is associated, the part of the first heating zone being halfway between a first end of the heater arrangement and a center of the heater arrangement or is closer to the first end of the heater arrangement than to the center of the heater arrangement, and the temperature sensor for the second heating zone is positioned to measure a temperature at a part of the second heating zone, the part of the second heating zone being halfway between a second end of the heater arrangement and a center of the heater arrangement or is closer to the second end of the heater arrangement than to the center of the heater arrangement.
