Wherever temperatures are measured, temperatures must also be simulated. The Pt100-simulator is suitable for a wide area of applications. It has a wide range of simulation, which is resolved in 0.1 °C steps and makes many assignments in chemistry-, measuring-, controlling-, medicine and household applications, food industry, vehicle construction, air- and space travel and power plants easy to solve. Often in the past several simulators had to be used alongside to achieve either resolution or the range of the relevant application. As an extra advantage to the user temperatures can be entered in degrees celsius. Additional extensive conversions and readings in tabulation sheets are no longer necessary. Features: — Simulation range -100 °C up to +500 °C — Resolution 0.1 °C — Calibration in accordance to DIN EN 60751 — Simulation of line resistance 10 Ω, 20 Ω or 30 Ω — Sturdy aluminium-housing

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).

The precision RTD simulator is used where measuring instruments or controlling means with high precision must be examined or calibrated. The simulator is suitable for calibration laboratory and service centers which need a computer-controlled resistance decade for the automation of calibration procedures. All standard platinum and nickel RTD can be simulated with very high accuracy according to scales ITS 90 or IPTS 68. Temperature regulators, transducers etc. often supply a pulsed signal current in order to reduce the self-heating of the RTD. Devices with electronic simulation of RTD are therefore inclined to swinging and do not function with this application. Features: — Simulation of Pt100, Pt200, Pt500, Pt1000, Ni100 and Ni1000 sensors — Accuracy 0.02 °C — Temperature scales ITS 90, IPTS 68 — Real Ohm simulation — Control manually or remotely via RS232/IEEE488/USB Converter

High-precision angle measuring system with +/-0.1s accuracy for measuring and calibration applications. The signal sampling is done by an interferometric operating principle (laserscale) The graduation period is 1µm, the generated signal period of the output signal is 250nm. Scale errors are self-compensated by using six reading heads in a special arrangement. The measured values can be output in csv format via the USB interface. The software for measured value acquisition and storage is included in the scope of delivery.

This high-precision calibration source is able to measure currents up to ±50 mA, voltages ±100 V and temperature setpoint values of 12 thermocouple types, including R, S, B, J, T, E, K and N. Voltage drops across the measuring leads can be easily compensated via the sense line. With “thermoelectric voltage simulation” you can enter °C, °F and K, the temperature scales ITS-90 or IPTS-68 and the reference junction type constant/external. Furthermore, when simulating thermocouples a calibrated external reference junction can be used, with the calibration data being taken into account in the device. The device can be operated both via the keypad and via the Ethernet and USB interface. Features: — DC voltage up to ±100.0000 V, ±0.002 % — DC current up to ±50.0000 mA, ±0.005 % - Thermocouple simulation of R, S, B, J, T, E, K, N, M, C, D, G2 - Automatic sequence function (ramp function)

The precision Pt100 simulator is used wherever measuring instruments or controlling systems have to be tested or calibrated with great precision. The standard version model 4506 simulates 24 set temperature values. Totally different temperature ranges are required in the case of special applications, such as in the food industry, the medical science etc. Model 4506 S is recommended for these applications and can be fitted with 24 temperature values according to customer specifications. A distinctive feature of these simulators is their simple operation. The resistance values required for simulation are directly set in °C. There is no need to use loof-up tables. Today in many cases a certificate is needed more than ever force measurements. This certificate is available under order code 45DKD-.. . Features: 24 set temperature values Calibration per DIN EN 60751 Resistor material: MANGANIN®, TK ≤ 10 ppm/K Pt100, Pt500, Pt1000 Available with DKD Certificate if required

Maintain the high accuracy of your BlowerDoor measuring technology by regularly submitting it to a calibration. Benefit from the high accuracy of the BlowerDoor measuring technology: At ± 4% or rather ± 5% (flow rings D + E), the accuracy of the BlowerDoor testing flow rings – as well as that of the pressure gauge DG-700 (± 1%) or DG-1000 (± 0.9 %) – clearly exceed the minimum legal requirements. The manufacturer’s calibration as well as the calibration with DAkkS-certificate, are subject to the highest quality standards. When calibrated, all measuring systems undergo a preceding functional test. If required, we will gladly provide you with a replacement device at favorable rates and conditions, while your BlowerDoor measuring system is being calibrated or repaired.

The KAL 100 / 200 calibration device combines a pressure transmitter and pressure gauge.

Calibration in mmHg (optional) makes the system ideal for applications in accordance with the regulations for users of medical products, e.g. blood pressure monitors and infusion/suction pumps.

To ensure that an instrument provides accurate measurements, regular calibrations are necessary. Calibration means to operate a target-performance comparision using a measuring instrument and a traceable reference. Calibration of instruments is essential in every area where sensitive measurement technology is used, e.g. in the manufacturing of sensors. It is the only way to guarantee quality standards and prevent defects arising in processes and products from the outset. For companies wanting to attain ISO 9001 certification, regular calibration of testing equipment is a requirement. halstrup-walcher has been accredited by the German calibration service DKD and Deutsche Akkreditierungsstelle GmbH (DAkkS) as a calibration laboratory in accordance with DIN EN ISO / IEC 17025 since 1999 – among other things for calibration of pressure measurements.
