Radar Tester

Many people question whether there is any danger for the person using GPR equipment, and the answer is no. Although “ground penetrating radar” may sound like a hazardous technique, it is extremely safe and emits roughly 1% of the power of a cellular phone signal.

The term bandwidth is the frequency difference between upper frequency and lower frequency on EM spectrum radiation. It is expressed in Hz.

All these are units of power measurement , dBm refers to decibel related to 1 milliwatt, dBW refers to decibel related to 1 watt

Vibration Analysis (VA), applied in an industrial or maintenance environment aims to reduce maintenance costs and equipment downtime by detecting equipment faults. VA is a key component of a Condition Monitoring (CM) program, and is often referred to as Predictive Maintenance (PdM).

The vibration velocity, acceleration, and expansion in a frequency range of 10 Hz to 1 kHz can be measured. The cables of the vibration sensors are 1.2 m long, so the vibration measuring device is able to record vibrations at different points of the component to be tested.

Vibration sensors are sensors for measuring, displaying, and analyzing linear velocity, displacement and proximity, or acceleration. Vibration — however subtle and unnoticed by human senses — is a telltale sign of machine condition.

The term Duty factor is the amount of time radar transmits compare to listening time. It is often expressed in percent. It is calculated by multiplying PRF and pulse width OR

by dividing pulse width with PRT
