Product Description

Application: 
The sensors can be widely used at those work sites which need overheat protection. When the sensors are fixed in those facilities that need overheat protection, they are able to keep the facilities from accidents and damages caused by overheating. 

Features 
The sensors are the special ones used for overheat alarm and protection. They are made from the advanced technology introduced from abroad. PTC temperature-controlled sensors are made of mini heat-variable resistors. They are of small size, endurance strength, good stability and excellent sensitiveness. All the technical criteria have reached the level of the same products in the world. 

Usage 
In operation, you may use one piece or several pieces connected in series, which can control the temperatures at different points and are good to reduce the cost.

Technical data 
The controlled temperatures of the sensors range from TK60ºC to TK180ºCore. There is a 5ºC interval between the controlled-temperature TK according to the specification. We are able to make such sensors between one and six cores according to customers' requirements.
