Dimetix DEH-30-500 Laser Distance Sensor

The selection should be based on the actual distance, tolerance, target speed, surface, and control system.

• For machinery, cranes and trolleys in hot plants where ±3 mm is sufficient.
• For metallurgical processes where the sensor can be kept away from the heat source and protected from radiation, dust, and splashes.
• For applications of 100…500 m that do not require 4-20 mA.
• For installations where a lower consumption version than the DPE models is desired.

Alternativas dentro de la Serie D: DPE-30-500 si se necesitan 250 Hz y -40 °C; DEN-10-500 si se necesita ±1 mm o 4-20 mA.

Ejemplos de aplicaciones documentadas con tecnología Dimetix, en las que la medida de distancia se usa para obtener posición, nivel, deformación o dimensión.

Transfer trolleys in steelmaking

A documented system replaced multiple microswitches with two laser sensors and reflectors mounted on the carriage. This solution allowed for variable stop positions and prevented impacts with end stops. The sensors were protected in housings with cooling and air purging to withstand heat and dust.

Hot metal level

Dimetix documents level measurement of cast steel and iron from a remote position to prevent overflows. The design must isolate the sensor from thermal radiation and consider dust, fumes, and ambient temperature; the +60 °C of the DEH is the permissible temperature of the sensor, not that of the metal being measured.

Crane positioning in heavy industry

The absolute measurement allows for control of bridge and carriage travel without relying solely on mechanical limit switches. In long bays, a reflector can be used to extend the signal range.

Machinery in dusty and hot environments

La Serie D admite carcasas y chaquetas de refrigeración por aire. La purga de la ventana óptica se emplea cuando hay deposición de polvo.

• Interfaces: RS-232, RS-422/RS-485 y SSI; USB para configuración.
• Salida analógica: No dispone de salida analógica integrada.
• E/S digitales: 1 salida digital + 1 entrada digital.
• Ethernet industrial: PROFINET, EtherNet/IP y EtherCAT mediante cubierta opcional.

• The DEH-30-500 does not have a 0/4-20 mA output. If an analog signal is required, select DPE, DEN, DAN, or DAE.
• Para calor radiante o temperaturas por encima de la especificación del sensor debe recurrirse a distancia, aislamiento, sombra o refrigeración. Dimetix ofrece chaquetas de refrigeración por aire para la Serie D.
• In atmospheres with dust, smoke, or particles, the optical signal may deteriorate; an air purge helps keep the window clean, but the solution must be validated in the actual application.
• A grandes distancias, la alineación y la estabilidad mecánica del soporte influyen en la medida.

En aplicaciones críticas conviene validar la superficie objetivo, luz ambiental, geometría, contaminación de la óptica, velocidad y atmósfera antes de fijar el rango útil.
