Opsens’ OTG-A fiber optic temperature sensor offers the highest performances in the industry. The OTG-A sensor uses the well proven technique based on the temperature-dependent bandgap of Ga. As crystal as the temperature transduction mechanism. Its small sensing Ga. As crystal located at the tip of the optical fiber makes it convenient for tip measurement applications. Combined with Opsens’ Ga. As signal conditioning technology and with the inherent advantages of fiber optic, the OTG-A delivers unprecedented repeatability and reliability in the most adverse conditions such as high level of EM, RF, MR and microwave field environments. The standard operating range of the OTG-A is from 40 °C to +250 °C. Higher temperature ranges up to 350 °C are available upon request.
Wavelength of maximum Absorptivity difference λ 1= 660 nm
In a carbon arc lamp, the electrodes are carbon rods in free air. To ignite the lamp, the rods are touched together, thus allowing a relatively low voltage to strike the arc. The rods are then slowly drawn apart, and electric current heats and maintains an arc across the gap. The tips of the carbon rods are heated to incandescence, creating light. The rods are slowly burnt away in use, and need to be regularly adjusted to maintain the arc.
The situation before the light switch is turned on. No power is applied and the lamp is OFF
