A simple voltage feedback loop stabilizes the bias of the directly coupled field effect transistor and bipolar transistor stages. The use of a constant current source maintains the stability of the bias voltage of the base 03. The DC voltage feedback of the emitter of the bipolar transistor can be used to control the value of the constant current by selecting the appropriate resistor value.
Explosion Proof Temperature Sensor
The model of explosion-proof temperature sensor is wzpk-22i-b, which is made of stainless steel and has explosion-proof performance. If you want to conduct reliable temperature measurement, you first need to select the correct temperature instrument, that is, the temperature sensor. Thermocouple, thermistor, platinum resistance (RTD) and temperature IC are the most commonly used temperature sensors in testing.
The changes of physical parameters with temperature include expansion, resistance, capacitance, electromotive force, magnetic properties, frequency, optical characteristics, thermal noise and so on. With the development of production, new temperature sensors will continue to emerge.
