Sensor profiles problem surfaces

A Panasonic Electric Works UK product story

Matsushita Electric Works has enhanced its range of measurement sensors by introducing the new SUNX HL-C1 laser measurement system.

Matsushita Electric Works has enhanced its range of measurement sensors by introducing the new SUNX HL-C1 laser measurement system.

Using charged coupled device (CCD) based technology, the sensor is able to quickly and precisely inspect surfaces that have historically posed problems for analogue based noncontact measurement equipment.

Black rubber and specular objects, including glass and wafers, can now be reliably and accurately measured using the new SUNX HL-C1 laser based measurement system.

Suitable applications for the HL-C1 series include measurement of the eccentricity of steel shafts, coplanarity of IC pins, thickness measurement of brake discs and tyre tread measurement.

Containing an extremely compact controller, the unit can accept the connection of up to two measurement sensor heads.

This allows thickness measurement to be carried out easily using built in calculation functions.

The sensor heads themselves are available in two styles: one for measurement of diffuse type surfaces, including black rubber and machined metal; and the other for specular objects such as glass and highly reflective surfaces.

Both styles offer two measurement ranges and are capable of measuring to accuracies of 1um.

Configuration of the controller can be performed using either a compact touch screen console or PC based configuration software via the built in RS232C communications port.

This port can also be used to transmit measurement data to a third party device, or the internal decision-making capability can be utilised and information accessed via digital I/O connections.
