The company BA-Messtechnik (former Bruno Richter) is one of the leading manufactures of gauges for In-Line dimensional measurement in steel and metal industries.

We measure In Line in cold and hot rolling mills

• the DIAMETER and PROFILE of wire, bars, profiles, tubes, pipes…from 0,1 mm dia to 1000 mm dia. and more
• the WIDTH of sheet metals, stripes…from 1 mm to 3000 mm
• the THICKNESS of sheet metals and flat materials from 0,02 mm to 200 mm

With a reputation in measuring technics of more than 40 years, we are one of the pioneers in the field of laser application for contactless dimensional inspection of long products. Our gauges are in service working worldwide in hot and cold mills.

We have a solution for each measuring problem. From the static one-axis shadow gauge with a display only up to the rotating gauge including up to date  data processing and Statistic Process Control.

For each application, we can offer the optimum customer specific configuration.

Special features of the diameter gauges type DO – beside the self-evident high accuracy – are:

• Easy maintenance – e. g. for cleaning quick exchange windows can be removed in a few seconds.
• Low running costs – e. g. the gauges produce the necessary cooling and purging air themselves by integrated fans, compressed air from the plant is not necessary.
• High reliability in service – e.g. the rotating gauges have a wireless data transmission, not a sensitive sliding contact.
• Long service life – e. g. DO gauges, delivered 25 years ago, are still in use. Of course, we do have spare parts in stock for these gauges and serve them.

The gauges are modularly designed and can be adapted acc. customer requirements. Data indication and handling can be from a simple display up to complex data processing and visualization by industrial PC’s. Remote displays, connection to HOST-computers and integration to networks are available.

The gauges are available for cold and hot applications: (oscillating gauges available for cold appl. only)

Gauges for hot rolling mills have special features like cooling and purging air, heat shields, water cooling, 2 wave pyrometers, a. s. o.

The diameter gauge heads type DO can be combined to 2-axis (=xy), to 4- or even to 6-axis measuring systems.

For circumferencial measurements, the DO gauge heads are integrated in rotating systems. These rotating gauges have data transmission by Industrialized Wireless LAN technic.

New developed gauges using “Light Section Technic” measure complexe profiles e. g. rails, I-sections... with high measurement rate and accuracy.
