Glass dome in the pyrometer limits the response of spectral from 300 nm to 2800 nm from 180 degrees of view. It also protects the thermopile sensor from rain, wind, etc. This construction of the second dome gives extra radiation protection among the inner dome &sensorcompared to a single do...
The combination of two capacitors that are connected together is known as a ganged capacitor. 4). What are the two types of variable capacitors? They are tuning capacitors and trimming capacitors. 5). What is the capacitance values of a variable capacitor? Typically ranges from 100pF to 500pF...
