General Description

The MSE-LD20HR Laser Distance Measurement Sensor operates up to a 20m ((65.6 ft) range off static or passing hot steel seamless rolled ring in difficult areas and in harsh hazardous environments. The MSE-LD20HR measures distances off of hot natural surfaces that are as hot as 1200°C (2192°F).

Designed specifically and optimized for measuring the distance to hot steel and steel seamless rolled alloy rings in ring rolling mill applications to determine the rolled ring diameter. The MSE-LD20HR provides precise detection and measurement of Hot Seamless Rolled Steel Rings from 600°C (1112°F) to 1200°C (2192°F)

For lower product temperatures the Model MSE-LT150 is available for measurement of cold/hot product at product temperatures up to 600°C (1112°F).

Straightforward alignment is easily accomplished via the visible red laser measuring beam.

Accuracy is ±1mm to ± 2mm (±0.039in to ± 0.079in) according to ambient temperature and surface reflectivity. Repeatability is ± 0.5mm (± 0.0197in) and the user scalable resolution is 0.1mm (0.0039in)

The zero offset and the span of the 4 - 20mA analog output are both user programmable. The distance offset is also user programmable, this allows the user to define a zero point independent of the analog output zero offset.

Provided with a user programmable digital switching output which is triggered by exceeding in the positive or negative direction a user programmable distance threshold. The hysteresis of the digital switching output is also programmable.

The MSE-LD20HR is provided in a robust dust and waterproof protected IP66 enclosure. Standard operating temperature range is -10°C to 50°C (-4°F to 122°F). As standard the MSE-LD20HR is supplied with water cooling and separate air purging. In this arrangement, a sealed water coolant radiator is provided. The allows for operating temperature range to +80°C (194°F) with water cooling chilled at 20°C (68°F). An air purge inlet is fitted in the front nozzle of the housing and air is vented out the front of the nozzle and in front of the lens providing positive pressure too help keep the lens clean. As an alternative to water cooling Vortex cooled air can be used. An optional internal PTC heater is available for operation down to -40°C (-40°F). An optional protective heat shield or a kevlar heat reflective protective cover is available for additional protection for elevated temperature applications.

The low cost MSE-LD20HR Laser Distance Meter provides a highly accurate measurement reading. It is ideal for diameter determination, and checking position of the hot rolled ring.
 
Supplied as standard with a either RS232 or an optional RS422 or an optional RS485 serial interface with a 2400 to 38,400 Baud Rate & a programmable 4 - 20mA 16 BIT analog output.

Optional ProfiBus DP, ProfiNet, and Ethernet TCP/IP Field Bus Interface Options are also available. DeviceNet and EthernetI/P Field Bus Interface Options will soon be available.
