Abstract

A temperature sensor of a simple construction using PTC devices which efficiently detects a temperature in a wide area of a planar heater is realized. The temperature sensor has excellent durability, manufacturability and installability and can be manufactured at reduced cost. For this purpose, the temperature sensor comprises a plurality of temperature detection chips formed flat, each using a PTC device, enclosed by a pressure resisting member, and connected in series by a temperature detection signal cable. The temperature sensor is further laminated between layers of an insulating film and, as a whole, formed like a ribbon.

Description

technical field

[0001] The present invention relates to a temperature sensor for detecting temperature changes in a flat heater for floor heating and various other heating, and to a heating system using the temperature sensor. Background technique

[0002] Various planar heaters are known for use in electric floor heating systems. A conventional example has rope heaters arranged in a zigzag on a plane of a predetermined size (for example, Patent Document 1). Another conventional example has a heating material mainly made of carbon printed on a thin layer of an insulating film such as PET (polyethylene terephthalate) in a predetermined width and thickness, at predetermined intervals, and in stripes or tapes. Ethylene glycol formate)) (for example, patent document 2).

[0003] Such a floor heating system uses an overheating prevention device or an excessive temperature rise prevention device (for example, Patent Document 1), which uses a bimetal thermostat, a thermal fuse, o...
