What is the principle of handheld steel bar position measuring instrument?
The principle of handheld steel bar position measuring instrument is electromagnetic induction. It consists of transmitter and receiver. First, the transmitter will emit electromagnetic waves of a certain frequency and amplitude. When these electromagnetic waves propagate through the concrete structure, if they encounter steel bars, reflection and interference will occur.
A receiver then picks up these reflected and interfered electromagnetic waves and converts them into distance data. According to the received signal, the handheld steel bar position measuring instrument can calculate the distance between the steel bar and the instrument, thereby determining the position and direction of the steel bar.
