Universal calibrator - DIGISTANT® 4420

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

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 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

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"
