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

The CCG Series of annular load cells are designed for the measurement of compressive forces, both continually and periodically, and are often used in critical bolted installations to monitor bolt tension. They are also used in cable tension applications where they are mounted at the anchor point. Their low profile makes them ideal for use where space is limited. The CCG series can be entirely customised to meet your specific requirements, including the IP rating to IP68 for fully submersible applications and temperature range up to 200˚C. The CCG Series can be supplied complete with accompanying instrumentation with a UKAS traceable calibration service, please contact our technical sales team.

The high-precision calibration laboratory is accredited according to DIN EN ISO/IEC 17025 for flow calibration of flowing gases. The EP calibration laboratory is accredited by the DAkkS according to DIN EN ISO/IEC 17025:2005 for calibrations of gases in-house and on-site under the procedure number D-K-21444-01-00. We offer calibrations for gas flow measurement as well as temperature, humidity and pressure measurements. In addition, we calibrate all measured variables of the test bench directly at your site. Our experienced technicians also check the harmonious interaction of all sensors, so that the entire system is perfectly tuned. The opening of our new calibration laboratory in Asia enables us to offer you even better service internationally.

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.

The portable, battery-operated KAL 84 calibration system combines a pressure transmitter and pressure gauge. These can be used to test and calibrate pressure sensors and other pressure gauges for low pressures both quickly and easily. A high degree of accuracy and excellent reproducibility of results combined with a robust design give the system all the functionalities required for laboratory and service applications. 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.
