Frequency Response Analyzers
-
Frequency Response Analysis (also referred to as Transfer Function Analysis) measures the output spectrum of a system relative to a stimulus, and is used to characterize the dynamics of the system under test. The technique measures the magnitude and phase relationship between output and input waveforms as a function of frequency. The input signals may be from a wide range of sensors including acoustic (microphones/sonar), mechanical (accelerometers/displacement transducers), optical (photodetectors), and electrical (amplifiers).

Frequency Conversion Rotating Magnetic Fla
MT-2XCF
-
MITECH MT-2XCF rechargeable frequency conversion rotating magnetic flaw detector is based on principle that the leakage magnetic field can absorb the magnetic powder. Make use of magnetic yoke magnetized the workpiece of ferromagnetic material. If there has defects it will produce leakage magnetic field that will adsorb magnetic powder. We could detect the flaw by observing the density of adsorption magnetic powder. It adopts large capacity lithium battery. By the inverter and the phase shifted signal processor to provide power for the detector, it solves the shortcomings of traditional magnetic particle detector relying on the 220V power supply. It has low power consumption and can continuous work for more than 6 hours. And the battery can be charged when the detector is on and off. Especially suitable for the field testing. It can choose the current frequency according to the flaw depth with unique frequency conversion communication design, that improve the detection sensitivity. It’s widely used in aircraft manufacturing, boiler and pressure vessels and other fields. It is a necessary professional precision instrument of quality control, in-service safety monitoring and life assessment.

Radio Frequency Cable Tester
RFCT
-
Textron Systems’ Radio Frequency Cable Tester (RFCT) allows for on-site testing and maintenance for radio frequency (RF) transmission paths within a platform. Using preconfigured databases of sweep parameters and pass/fail criteria, the RFCT quickly determines the status of installed RF cables. The RFCT checks each cable’s performance characteristics to include voltage standing wave ratio (VSWR), insertion loss (IL), phase and phase matching. If a cable fails a test, the RFCT automatically determines the distance-to-fault (DTF). With its intuitive touchscreen-based user interface and lightweight, ruggedized packaging, the RFCT is the gold standard for operational-level RF cable testing.

Frequency Sensing Relay
-
This relay is a frequency monitoring relay with four stages of adjustable frequency pick up & drop out points. Each frequency set point can be set for under or over frequency operation & has an independent time delay driving an output relay. An undervoltage lockout is used to disable the four frequency outputs when the voltage falls below a preset level. Each of the four setting stages has a rate of change of frequency (ROCOF) element with an independent time delay.
