Distance Laser Sensors

Metrology Resource sells laser measurement sensors for accurate laser distance measurement using phase shift technology. We provide products described as laser distance measuring device, non-contact measurement sensor, laser measuring device, laser measurement sensor or rangefinders.

Distance laser sensor MRL2 modelThe MRL3 Laser Measurement Sensor is a powerful and robust laser measuring module designed to meet the demands of the industrial measurement market. They accurately measure to any opaque surface. These laser measurement devices offer many outstanding features including compact size, simple interfacing via serial RS-232 or analog outputs and a visible laser spot. Read the technical specifications in the data sheets.

The MRL3-H model is identical to the MRL3 sensors except, it has an extended temperature range down to -40C.

MRCs two MRL3 models have laser measurement ranges from 0.05 m to 150 m. All models are standard with RS-232 serial interfaces, digital outputs and programmable digital inputs. All models are made to IP65 specification.

Principles of Operation

The MRL3 device is a phase shift laser measurement device that compares the outgoing and returning wave signals to determine the distance to a target. These frequency waves are timed to an internal clock to measure the time it takes for the laser light to go out and return to the sensor. This phase shift is often calibrated based on ambient lighting conditions and temperature. Click to read more about phase shift technology.
