AR1000 Laser Distance Sensor

Using a reflective target board, the sensor will measure distances up to 150 meters. Ideal for measuring fill levels and material height monitoring, the AR1000 sensor can hold up to very tough environments.

The AR1000 laser distance sensor is ideal for crane and hoist applications, position measurement, or for monitoring fill levels of bulk material. The unique sensor uses phase shift comparison measurement principles (of light) to accurately measure distances of 30 meters. Longer ranges to 150 meters are possible with the use of reflective target boards (3M Scotchlite 3279).

Typical speeds for the AR1000 laser distance sensor are 6 Hz, but 50 Hz sampling can be realized with white targets at close ranges with small target movements.

The sensor is designed for industrial environments with NEMA-4, IP65 enclosure ratings, permitting the sensor to be directly rinsed with water! Typical data outputs are serial RS232, RS422 (optional) and current loop 4-20 mA signals.

This sensor is highly versalite, able to measure distances both indoors and outdoors, but may have limitations to extremely dark targets or measuring through steam, fog and smoke where the signal is obstructed. However, the AR1000 measure to hot, glowing steel near 1000°C

A special AR1000H version is available with an internal heater, making the sensor suitable for operation to -40°C (-40°F). Users can configure the cycling of the heater through the serial interface.

Key Features

• Typical speeds are 6 Hz, but 50 Hz sampling can be realised with white targets at close ranges with small target movements.
• The sensor is designed for industrial environments with NEMA-4, IP65 enclosure ratings. Typical data outputs are serial RS232, RS422 (optional) and current loop 4-20 mA signals.
• This sensor is highly versatile, able to measure distances both indoors and outdoors
• The AR1000 measures to hot glowing steel near 1000°C and it can measure to any opaque surface even radiating steel.
• A special AR1000H version is available with an internal heater, making the sensor suitable for operation to -40°C (-40°F). Users can configure the cycling of the heater through the serial interface.
• The accuracy of the measurement is typically +/-2.5 mm, but it will depend on the reflectivity of the target surface, lighting conditions and temperature conditions.

OUTPUT INTERFACES

Acuity offers the following standard and optional outputs for the AR1000 laser rangefinder devices:

• Standard RS-232 Serial Output - All sensors come with an RS-232 serial output on the 2m (6 foot), 9 pin cable that connects to PC style serial ports after the user attaches a DB9 connector. Serial output is ASCII and may be configured as either decimal or hexadecimal. The maximum baud rate is 38400 baud.
• Standard RS-422 Serial Output - For long distance communications (more than 20 to 30 feet, depending on the baud rate), the RS-232 serial output may be replaced with an RS-422 serial output. The available sample rates, formats and software configuration commands are all the same as for the RS-232. Acuity recommends an RS422 to RS232 converter to monitor the interface from a PC computer serial port.
• Standard Current Loop Output - A 4-20 milliamp current output is a standard output for the AR1000 laser distance sensor. The zero and span for the current loop output may be set at any location.. The span point (20 mA) may be made closer than the zero point if desired. The 4-20 mA output has a maximum voltage capability of 10 volts, and it is suggested that a 400 to 500 ohm load be used at the reading instrumentation for best accuracy.
