General Purpose Basic Carrier Demodulator
CD15
-
The CD15 Sine Wave Carrier Demodulator operates with variable reluctance transducers to provide a DC output signal for dynamics as well as steady state measurements. A 5kHz sine wave excitation is applied to the two inductance ratio arms of the transducer and the resulting output is demodulated and amplified using the latest integrated circuit techniques. The DC output is obtained from an active filter circuit and gives a uniform response from steady state to 1000 Hz. The low impedance sine wave excitation allows operation with the transducer located over 1,000 feet from the CD15.

HighReach Measuring & Controlling System Co.,Ltd
At The Radar Level gauge Antenna emits and Narrows at The Microwave Pulse. This Pulse propagates in Space AT at The Speed of Light. The When IT Encounters at The Surface of at The the Measured Medium, Part of the ITS Energy IS the REFLECTED the Back and Received by at The Same, Antenna. At The Time interval The Between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium.Because the electromagnetic wave propagation speed is extremely high, the time interval between the transmitted pulse and the received pulse is very small (on the order of nanoseconds). It is difficult to confirm. The 90X series 26G radar level gauge uses a special demodulation technology To accurately identify the transmitted pulse and the time interval of the pulse is received to further calculate the distance of the antenna from the surface of the measured medium.
