Model 9180 supports force, pressure and torque sensors operating on the strain gauge principle, as well as the connection of position and angle sensors in potentiometer or DC/DC configuration. It also allows the measurement of process signals ± 1 V/ 5 V/ 10 V or 0 ...1 mA, 0(4) ... 20 mA. The current measured value is indicated on the 14 mm high LED main display, while a second display located directly below provides a reading of the peak value. The display is particularly suitable for highly accurate measurements due to the high accuracy of 0.1%. It is also possible to monitor up to 4 limit values and provide the results via relay or transistor outputs. Thus the process value display can be used for classification, process and control tasks. The current measured value is frozen on the display by activating an external HOLD signal. The TARE function is useful for balancing out previous loads for example.

Automatic inspection and test unit: Automatic choice of measuring ranges from 200 μΩ to 20 kΩ Resolution up to 1 nΩ Standard interfaces IEEE488, RS232, RS485, (USB and Ethernet option) Checking of tolerances, classifi cation with statistics Highest measuring accuracy: Measuring error ≤ 0.01 % Future-orientated measuring method with thermal e.m.f. compensation. High level of stability due to constant comparisons with internal reference values. Inductive probes: Current regulation results in voltage-free disconnection, calculation of cooling curves of coils. Menu control: Setting for measuring current entry for absolute or relative limits, classifi cation with statistics, bar display for calibration of measuring probes, determination of resistivity, and many other functions. The operation of the measuring section of the RESISTOMAT® model 2304, 2305 high-precision inspection and test unit is based on an upgraded 4-wire design.

Based on its specifications, this device can be used in various applications. It is especially suitable for resistance measurement on insulating materials such as e.g. cable insulations, foils, textiles, surfaces, insulating liquids,etc. With a test voltage of 45 V, 100 V, 250 V and 500 V the device fulfi ls most test specifi cations such as e.g. DIN 51953, 53482 and 54345. The guard switching allows single resistance measurements in a triangle wiring. This could be e.g. a two line cable with common shield or the measurement of insulating materials on a guardring measurement cell. The selection of the measurement range is done manually or automatically. Fast subsequent measurements can be realized by the internal limit value indicator. When the measured value exceeds the limit the limit value indicator switches and activates a potential-free relay output. The megohmmeter RESISTOMAT® model 24508 is the right instrument for its use in laboratory as well as in industrial applications.

The SENSORMASTER 9163 covers a wide range of applications in which process values need to be measured, displayed, analyzed and transferred to higher-level control systems. Typical applications include measuring geometric values in production, for instance differential measurements, or testing material properties in the laboratory. The measured values can be transferred via USB, RS232 or analog output.

Inside the multi-component force transducer are two webs, each offset by 90°, each with a strain gage full bridge, which convert the radially acting X / Y forces on the guide bush into an electrical signal. Due to the sensor body made from a block with its special structure, the sensor has a very high degree of dimensional accuracy and low crosstalk between the two forces. Due to the special design, the sensor has excellent linearity properties and is designed for a long service life in dynamic applications. The two independent signal connections allow flexible adaptation and further processing. Features: — Measuring ranges: 0 ... 4448 N / 0 ... 2224 N (0 ... 1000 lbs / 0 ... 500 lbs); 0 ... 8896 N / 0 ... 4448 N (0 ... 2000 lbs / 0 ... 1000 lbs) — Further measuring ranges on request — Non-linearity < 0.1 % F.S. — Low cross talk < 0.75 % F.S. — High dimensional accuracy, because sensor is made from one part — Excellent price/performance ratio

The RESISTOMAT® model 2320 is a universally applicable and easy to operate measurement device for low-ohmic resistances. The light and handy device in a stable IP54 plastic housing with membrane keypad is likewise suitable for use in service, laboratory or on the production floor. The power supply is done via built-in rechargeable battery packs or by standard batteries. If need be, the temperature of samples can be measured and the sample resistance is subsequently compensated to fit the value at 20°C. This applies for samples with resistances depending on the sample’s temperature. The temperature coefficients for copper and aluminium are included as standard. A third and fourth coefficient may be set individually for any given material to be measured. Features: — Measuring ranges from 40 mΩ to 4 kΩ — Resolution up to 10 μΩ — Measuring accuracy 0.05 % Rdg. — Autorange — Temperature compensation — Bipolar measurement — Input voltage protection up to 415 Vrms

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.

As an angle sensor that is both accurate and economical, this rotary potentiometer is suitable for all types of analog angle measurement up to 350°. Typical fields of application include: —Position feedback in servo-systems —Pendulum weighing machines —Cam and butterfly flap positions —Jockey roller controllers —Measuring the tension of threads and tape —Trigonometric measurements at joints The heart of the potentiometric angular displacement sensors is an extremely precise, low-wear resistor track made of plastic. Due to its high resistance to abrasion, the sensors are particularly suitable for measurements for the purpose of quality assurance in ongoing production, where a long service life and large numbers of rotations are required. The potentiometric angular displacement sensor uses a multi-finger slider system with precious metal contacts. This ensures good contact even when moving at high speed and in the presence of vibrations.

The 0.02 class calibration resistors excel in their modern design and small mechanical dimensions. Their ruggedness also ensures a long life. Calibration resistors of the 1240 series are used wherever very constant operating standards are required. Typical main areas of application therefore include: — When normal resistors prove to be too large scale — For test and calibration of resistance measurement devices — For tests on electrical temperature measuring equipment — For laboratory setup of a Wheatstone bridge — As shunt resistor for accurate current measurement — As part of standard equipment in research laboratories — For a large part of measurements in calibration laboratory. Features: — Range 10 μΩ ... 100 kΩ — Low capacitance and low inductance design — Suitable for direct current and technical frequencies — High stability < ± 0.01 % over years

The force measuring chain is an universal reference measuring chain for the calibration of press-fit force measuring equipment. It finds applications in the quality assurance, commissioning and equipment monitoring fields. A DAkks calibration certificate is included so that the force measuring chain can be traced back. The calibration is traceable through accreditation at the German Accreditation Body. The calibration certificate records the displayed values for mounting positions at 0°, 120° and 240°. During calibration in field, the reference load cell is inserted in line with the flux of the press-fit measuring equipment. The force application is of central significance here for the quality of the measurement. Special force application parts are required, so that the line of action of the force agrees as exactly as possible with the geometrical axis of the load cell that is to be measured (central loading).
