In the field there is a frequent need to measure sensor readings rapidly and easily right at the sensor and to transfer them directly to a PC without additional amplifiers or converters. The 9206 USB sensor interface can satisfy this requirement admirably, thanks to its „plug & measure“ design. The USB connection means installation could not be simpler. Typical applications: —Mobile test measurements via laptop —Laboratory test set-ups —Instrumentation and control —Diagnostic measurements in the chemical industry —PC-based recording of expansion figures in bio engineering The USB sensor interface takes its supply from the connected PC via the USB port, and uses it to generate the power supply for the sensors. The initial settings and sensor settings are made by burster in-house and saved in the USB sensor interface. These can then be fine-tuned by the customer.

The incremental digital displays are used in combination with our high-precision displacement sensors 8738. The digital technology of these measuring systems satisfies high demands for precision and long service life, as is required more and more nowadays — in measuring laboratories — in production — in testing laboratories — in workshops and many other areas. Typical uses: —Automatic assembly machines —Semiconductor industry —Keyboard tests —Robot controllers —Testing of shafts and planes —Measurement of differential displacement With its phenomenal resolution of 0.1 µm and the high response frequency of 20 MHz, the 9140 is a powerful display unit with a compact design. The comparator function integrated as standard allows for direct evaluation of measurements almost in real-time; these can be processed further by a higher-level controller. A rather more comprehensive acquisition method is also integrated into the system.

The range of functions has been limited deliberately to ensure operation is simple and self-explanatory. With its unique, large and clear digit height of 20 mm, the digital display can be installed easily in process control panels and control cabinets. Thanks to the large choice of measurement signals that can be indicated, the display is ideal for use in a huge range of industry-based applications. As a simple and compact digital display, it can also be used as a multi-channel solution in laboratory or test systems, where several different measurements may need to be taken and displayed simultaneously. Specific characteristics: — Less expensive digital display — For force, pressure or torque measurements using gauge sensors — Two limit alarms optionally available — Extremely easy-to-read display with 20 mm digit height — Display range -1999 to + 9999 — TARE function — Scaling possible using teach-in procedure or by entering sensor data directly

The range of application for the high-precision resistance decades models 1406 and 1407 stretches from reference standard for precision measurements up to simulation ot a host of measuring transducers. They can be used for control in complicated equipments and systems, such as equivalent circuit in resistor networks. Another application is the use in switching circuits, as reproducible variable in laboratory and test assemblies. The decade resistors meet all the requirements of these differing functions as well as the resulting demands. The high-precision resistance decades models 1406 and 1407 are designed to meet the highest demands with regard to precision, temperature and long-term consistency. Many years at experience, tried-and-tested technology and the use of fieldproven materials guarantee the high level of precision. The decade resistors consist of low-capacity and low inductance wire windings of MANGANIN®.
