Laser Ranging Sensor
The model LRF laser ranging sensor is a non-contact ranging sensor that uses the laser phase method to measure the distance between the sensor and the object being measured. The sensor measurement range is 0.5m to 30m, and the indoor accuracy can reach ±1.5mm. The laser range finder has the characteristics of fast measurement speed, high accuracy, small product size, and easy use. It can be used in application scenarios such as tunnel vault settlement and arch waist convergence monitoring, bridge pier settlement monitoring, and object distance monitoring.

The model LRF laser ranging sensor is a non-contact ranging sensor that uses the laser phase method to measure the distance between the sensor and the object being measured. The sensor measurement range is 0.5m to 30m, and the indoor accuracy can reach ±1.5mm.

It can be used in application scenarios such as tunnel vault settlement and arch waist convergence monitoring, bridge pier settlement monitoring, and object distance monitoring.
The phase laser ranging sensor uses the frequency of the radio band to amplitude modulate the laser beam and measure the phase delay generated by the modulated light traveling back and forth to the measurement line once, and then converts the distance represented by this phase delay based on the wavelength of the modulated light. It uses an indirect method to measure the time it takes for light to travel back and forth from the measurement line. It is a photoelectric distance meter that indirectly measures time and is usually used for high-precision measurements.
