TESTING AND METROLOGY GMBH

The precision calibration unit combines high accuracy, low drift, low noise and superior long-term stability with multiple functionality and simple operation. Ramps, Δ+/Δ-, and multiple setpoint storage make the operation of the device easier for the user. For that reason the application possibilities are many: — Calibration of current and DC-voltage meters — Precise testing of thermocouple temperature measuring instruments — Calibration of controllers, sensors, detection devices and other devices used in process control — Open-loop process control with the aid of integrated ramp function Features: — High precision current and voltage source ± 52 mA, ± 30 V — Option: ± 22 mA, ± 60 V — Precision simulation for all conventional thermocouple types (optional) — Error limit 0.003 % Rdg. — Standard with RS232 and IEEE488 interface, USB and Ethernet (optional) — Current "SINK"

The DIGISTANT® model 4420 universal calibrator, built to use in the field, is ideal for checking and calibrating temperature measurement and control devices. The versatile functions of this portable unit allow to be used on-site or at a fixed location, on the test floor or in the laboratory. The unit allows the simulation and measurement of voltages, currents, temperatures and resistances.Simultaneous transmission and measurement allow, for example, controllers to be checked precisely. The automatic ramp function is used for controlling processes. The universal calibrator measures and simulates 14 models of thermocouples and Pt100. Features: Calibration and measurement unit for voltages, currents, temperatures and resistances All functions can be fully controlled and configured via RS232 interface Simultaneous transmission and measurement Automatic ramp function Simple menu assistance via display Voltage range ± 1 μV to ± 11.000 V Current range ± 200 nA to ± 22.000 mA

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).

Essential for direct reading and high-capacity torque wrench calibration! Mechanical loaders increase the accuracy ot torque test results while simultaneously reducing technician fatigue from pulling or pushing on torque wrenches during testing. A mechanical loader is the perfect accessory to increase the repeatability and productivity of the System 5 Digital Torque Tester. The drive system for each loader assures true 90-degree force application to eliminate force angle error in testing. In addition, the loaders mechanical advantage reduces technician effort and fatigue, particularly in high-capacity tool testing. SR Mechanical Loaders use the highest quality ball screws to assure smooth operation and extended service life. Welded steel frames and rigid transducer mounting plates assure torque load is properly resisted. Optimized gearing selection reduces physical effort to operate, enhancing productivity and ergonomic safety.
