General Description

The MSE-AL30 Laser Level Sensor is used to measure the liquid level of molten aluminum and control the liquid level of aluminum in a closed loop control system. The MSE-AL30 operates over a measuring range of 0.1m to 10m (0.32ft to 32.8ft) off of molten aluminum alloys as hot as 900°C (1652°F) with an accuracy of 1mm (0.039in).

The MSE-AL30 Molten Aluminum Laser Level Sensor uses the phase comparison principle for distance measurement. The laser sensor emits visible laser beams of different frequencies, receives the scattered laser return signal from the measured object, compares the received laser signal with the reference signal, and then uses a microprocessor to calculate the distance between objects corresponding to the corresponding offset. The measurement accuracy can reach mm level..

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

Accuracy is 1mm (0.039in) with repeatability is 0.5mm (0.0197in) and the user scalable resolution is 0.1mm (0.004in).

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-AL30 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). An optional internal PTC heater is available for operation down to -40°C (-40°F. Optional Secondary Environmental Enclosures are available for additional protection for indoor, outdoor and elevated temperature applications.

The low cost MSE-AL30 Molten Aluminum Laser Level Sensor provides a highly accurate measurement reading. It is ideal to measure the liquid level of molten aluminum and control the liquid level of aluminum in a closed loop control system..
 
Supplied as standard with a either RS232 or an optional RS422/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.
