Introduction:
Ultrasonic Partial Discharge Detector, this device can sense high-frequency signals generated by operating equipment faults, vibrations, leaks, and electrical partial discharges. It uses a unique heterodyne method to convert these signals into audio signals, allowing users to hear these sounds through headphones and see intensity indications on the meter. The heterodyne principle is like a radio, accurately converting signals into sound, making it easy for people to identify and understand. The advantage of using ultrasonic technology is that it is easy to understand and convenient. Ultrasound is a high-frequency short-wave signal that is not directly audible to the human ear. When we use the full-function ultrasonic detector, these sounds can be fully detected.
Product Features:
1. Can detect early fault phenomena before other detection methods such as infrared detection.
2. High sensitivity, capable of detecting weak signals like blinking.
3. Strong anti-interference capability, usable in complex environments.
4. Portable device, easy to carry and operate.
5. With long-distance probes or ultrasonic remote receivers, the detection distance of the instrument can be greatly increased, capable of detecting distances over 30 meters, and can detect distances over 45 meters.
