Controlador de temperatura uniforme
(Universidade Tecnológica Federal do ParanáMedianeira, 2012-10-05)
Temperature control is often required in some processes. In the middle factory, usually, there are devices known as temperature controllers that have a control on the output type 0 and 1 (on / off). However, this type of ...
Digital control system using a thermoelectric cell for temperature electronic devices testing
(Pato Branco, 2010)
This paper presents a temperature digital
control system for performance evaluation of electronic devices under different operating temperatures. The system is based on a thermoelectric module of Peltier effect, which is ...
Sistema de controle de temperatura de ar condicionado automotivo
(Universidade Tecnológica Federal do ParanáPato Branco, 2013-09-11)
This paper presents the development of a prototype system for temperature control automotive air conditioning which is designed to control temperature inside a vehicle through a temperature sensor. A system microcontroller ...
Determination of piglets' rectal temperature and respiratory rate through skin surface temperature under climatic chamber conditions
(2015-01-01)
In animal farming, an automatic and precise control of environmental conditions needs information from variables derived from the animals themselves, i.e. they act as biosensors. Rectal temperature (RT) and respiratory ...
Dynamic response analysis of a digital temperature controller with fiber optic sensor
(Pato Branco, 2010)
The aim of this study is to analyze the dynamic response of digital temperature controller using fiber optic sensors based Bragg grating. The controller designed using a fiber Bragg grating in feedback control loop, instead ...
Skin temperature of piglets as a biosensor for controlling the heating system in creeps with low power consumption
(2021-10-01)
A new technology, which uses suckling piglets as biosensors for the control of heating systems in creeps, is shown to be feasible regarding the thermal point of view and efficient use of electricity. This study describes ...
Sistema de monitoramento de temperatura e umidade para um silo
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de InformáticaEngenharia de ComputaçãoUTFPR, 2017-06-27)
Temperature monitoring in a silo is necessary because temperature is the main factor involved in the deterioration of stored grain. By controlling the temperature it is possible to reduce losses due to the proliferation ...
Incubation and rearing temperature effects on Hsp70 levels and heat stress response in broilers
(Agricultural Inst Canada, 2003-06-01)
Incubation temperature (IT) was changed to evaluate if 6-wk-old birds become more tolerant to heat stress. After 13 d of incubation, 470 eggs were submitted to low (36.8degreesC), normal (37.8degreesC) and high (38.8degreesC) ...
