DIGISTANT® Pocket Temperature Calibration and Measurement Unit
Model 4415

 

  
  • Calibration and measurement of 7 thermocouple types(K, T, J, R, S, L, N)
  • Internal and external reference junction
  • 2 progammable alarm functions and acoustic alarm
  • Storage of 50 measured values
  • Averaging of min./max values
  • Analog output
  • Hold function

Application

This portable and extremely handy temperature and process calibrator is ideal for use on location.Whether during servicing, commissioning or brief checks of measurement sequences on the test floor, the type 4415 always provides an economical solution for measurement and temperature calibration.The type 4415 DIGISTANT ® measures and simulates thermocouples of the types K, T, J, R, S and N in accordance with DIN/IEC 584 and L in accordance with DIN 43710.Measured and simulated values are indicated in °C or °F. The functions "Hold", "Memory", "Statistical" and "Alarm" make the quality test easy.The excellent stability of the output signal allows an effective test of the reliability on the controlled tools.

Description

The LCD display and the clearly arranged keypad allow easy programming (SET-UP) and operation of the type 4415 DIGISTANT ® . Operator prompting takes place in English.Measured values can be "frozen" with the hold function. Up to 50 measured values can be stored.The maximum, minimum and average values can be called up with the statistics function.Two alarms high and low can be programmed.The additional background lighting of the display and the automatic disconnection function render the DIGISTANT ® type 4415 a versatile measuring instrument.The pocket is powered by a 9 V dry-cell battery and the operating time is > 100 h.


High Precision Calibration Source for Voltage, Current and ThermocoupleDIGISTANT®
Model 4462

 
  • High precision current and voltage source± 52 mA, ± 30 V
  • Precision simulation for all conventional thermocouple types (optional)
  • Basic accuracy 0.005 % of reading
  • RS232- and optional IEEE488 interface

Application

The precision calibration unit combines high accuracy, low drift, low noise and superior long-term stability with multiple functionality and simple operation.Ramps, delta + / delta -, and multiple setpoint storage make the operation of the device easier for the user.For that reason the application possibilities are many:
- Testing current and 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 functions.
The DIGISTANT ® type 4462 can be used both as a stand-alone table-top device, as well as in automatic, computer-assisted manufacturing and testing systems.

Description

It is possible to set currents of ± 200 nA ... ± 52 mA, voltages of ± 1µV ... ± 30 V and, optionally, temperature setpoint values of 14 thermocouple types.The output value is fed back via the sensor line to eliminate voltage drops across the measuring leads.The device has an adjustable current/voltage limitation. An external voltage divider of 1 up to 1:1000 can be considered internally.With the thermovoltage sourcing option you can enter °C, °F and K, the temperature scales ITS 90 or IPTS 68 and the comparison point mode constant/external. Furthermore, when sourcing thermocouples a calibrated external comparison point can be used, whereby the data for calibration in the device can be taken into consideration.Indication of the source value is carried out in large 12 mm figures on an illuminated graphics-LCD.The device can be operated both via the keyboard as well as the interface.
