Recognition by the water temperature thermistor type temperature sensor and thermistor bimetal, as shown in Fig. This is where the water temperature thermistor is sending pieces of information, bimetal electric wire as receiving elements, both series. Send items namely water temperature sensor installed in the waterway in contact with the cooling water, VDO sensor, when the water temperature is low, the thermal resistance value is high, in the loop current is small, small heat VDO sensor manufacturers, resistance wire, wholesale VDO sensor, bimetal slightly curved, indicating needle in a low temperature region (C region). When the water temperature is high, the thermal resistance value is small, low-VDO sensors, current loop through a large, heat resistance wire is larger, a larger bending bimetal indicating needle pointing to the high temperature region (H region). Water temperature sensor temperature gauge uses a negative temperature coefficient thermistor, which is installed in the cylinder head water jacket, water temperature with temperature sensors. 1 thermistor thermistor temperature measurement 1; ⒉ information transmission parts; three pairs of metal sheet; ⒋ indicator pin; 5 information receiving member 1 thermistor; 2 a conductive sleeve; 3 conductive spring; afternoon copper joint; sg tube ; 6 side button; ⒎ conductive rod; 8 wire temperature sensor with the water table, water table and its terminal phase, and the other end through the sensor housing Ground. Continuous running for more than 12h, the output power will be less than about 90% of the rated power of the diesel generator is generally single-cylinder or multi-cylinder diesel four-stroke diesel engine, here I only talk about the basic principles of the work of a single-cylinder four-stroke diesel engine: diesel engine starting diesel engine crankshaft is rotated so that the piston reciprocates up and down on top of a closed cylinder through human or other power. Four stroke piston complete in motion: the intake stroke, compression stroke, combustion, and for power (expansion) stroke and an exhaust stroke. When the piston moves down from the upper intake valve opens, the air filter filtered fresh air into the cylinder to complete the intake stroke. VDO oil pressure sensor _VDO (certified) _VDO sensor provided by the Dongguan City, South City Zhongxin Electrical and Mechanical operation. Dongguan Nancheng Zhongxin Electrical and operating (zhongxin888.net.cn) Dongguan, Guangdong, industrial products leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
