Pneumatic Deadweight Testers

The multipurpose digital indicator TRANS CAL 7281 can be used wherever there is a need to perform high-precision, in-situ calibrations of sensing components used in equipment such as presses, torque tools or pressure-regulating systems. An optional factory calibration certificate or German-accredited DKD/DAkkS calibration certificate can be provided when the measurement device needs to be used as a reference. This provides a quick and cost-effective way of assessing a system with traceable documentation of measurement results. If a reference measurement cannot be made because the sensor location is difficult to access, it is still possible to test the zero point, the input, output and isolation resistance as well as the calibrating offset of the fitted sensor. It is also possible to check the indicating device by measuring the excitation voltage and simulating the characteristic values (mV/V or V) of the sensor used.

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 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

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
