Temperature
The first MTE-THOMSON operations coincide with the birth of the Brazilian automotive industry.
In 1955, the first engine was made in Brazil, for a Mercedes-Benz truck. From this industrial milestone on, a new expansion phase took place in the automotive market. The following year, 30% of imported vehicle components already had local suppliers. Later, in 1960, the federal government would demand that at least 95% of the passenger vehicles contained national components.
It was in 1957 that MTE inaugurated its production as Metalúrgica Termo-Elétrica, supplying the market with the first engine temperature sensors manufactured in Brazil.
The temperature sensor is responsible for measuring the temperature of coolants in liquid-cooled engines or the temperature of oil in air-cooled engines, thus working as a thermometer that transforms the temperature into electrical signals to be interpreted by the vehicle’s dashboard.
In 1975, a joint venture with American company Thomson International Co., gives birth to MTE-THOMSON as we know it. That is when the production of thermostatic valves starts, leading to the consolidation of the company as a reference brand and the most recognizable manufacturer of items for engine temperature control.
The thermostatic valve is responsible for this control, directing the coolant flow from the engine to the radiator.
In 1986, MTE-THOMSON begins to manufacture thermal switches, which activate various components of the cooling system according to the engine temperature. In 1990, with the development of new technologies, such as the application of automotive ceramics, the production of NTC and PTC thermistors begins. In Latin America, MTE-THOMSON is the only manufacturer of those internal components of temperature sensors.
In 2016, the company is the first to launch the EGTS, or exhaust gas temperature sensor, in Brazil, aimed at the medium/heavy duty market. This sensor is very important to help reduce exhaust gases, detect the temperature of gases, convert it into voltage (V), and inform the ECU so it can control the emission of pollutants.
With a pioneering spirit and a broad understanding of market demands, MTE-THOMSON has become a reference when it comes to all components of the cooling system – in charge of the temperature and thus the proper functioning of the engine.
