CALYS 150 field documenting multifunction calibrator is the top instrument of the range. It is the perfect tool for advanced process maintenance and use on test bench in all industries. Suitable for all field and lab measurements, it can simultaneously measure and generate over two isolated channels various signals of temperature, resistance, process, pressure and frequency in one single instrument. CALYS 150 does not only work as a simulator (IN / OUT) but also as a dual channel thermometer (IN / IN) to perform comparison calibration. It calibrates HART transmitters (HART communicator integrated into ACL500 modem) and thermistors. Providing extended functionalities (temperature simulation, scaling, steps, synthesizer, statistical functions…) and audit trails, CALYS 150 complies with both 21 CFR Part 11 and NADCAP Heat Treatment standards and makes advanced data exploitation and full data traceability easier. High performances for CALYS 150, for advanced use:

  • Temperature Up to 0.005 % RDG
  • Resistance Up to 0.006 % RDG and 50 KΩ range
  • Current: Up to 0.007 % RDG and 100 mA range + Loop Supply 24 V
  • Voltage: Up to 0.005 % RDG and 50 V range
  • Frequency: Up to 0.01 % RDG and 100 KHz range
  • Pressure: With an external pressure module (comparison calibration with a pressure pump)

Using this user-friendly instrument, calibration tasks can be quickly carried out over the whole process chain. Take the 900 g documenting process calibrator to the field with you during the whole week with 10 calibration procedures stored in the device. Run the procedure after connecting the probes to the instrument (Easy connect system®) and save the results for onsite easy and quick calibration. Back to the office, you can then upload the data on a computer in order to issue customized calibration certificates with dedicated calibration software DATACAL. IP 54, fully protected by an antichoc rubber holster, CALYS 150 integrates "easyconnect" terminals and a wide backlite display that makes it easy to use in any severe or dark conditions. When used with an external pressure module (ref. ACL433), CALYS 150 can measure and simulate pressure (comparison calibration with a pressure pump). CALYS 150 has also the capability to drive baths and dry-blocks when associated with the specific cable (ref. ACL600).

Easy connection system

CALYS_Easyconnect pressed_BD Connect your probes by simply pushing on the terminal top and insert wires of up to 3 mm or 10 AWG diameter and compensated thermocouple connectors. Wires are held tight between two brass plates ensuring thermal stability and a very good cold junction compensation for thermocouples. This system also enables 4 mm banana plugs and security connectors to be connected on the terminal top.

Further features

Scaling in measurement and simulation modesScaling allows process signals to be displayed in % of FS or in all other units. This function also allows sensors to be corrected after a calibration.
Relative measurementThe features allows the following :

  • Programming a reference value different from the one of the instrument (NUL function).
  • Subtracting of constant value by measuring or programming it from a measured value (TARE function).
Simulation menuSimulation value is set by entering value on keypad or by changing the specific digit with the cursor.
Square rootIn current measurement and simulation, this function allows taking into account a quadratic signal coming from transmitter of type ΔP.
Statistical functionsContinuous display of average, minimum and maximum value of the signal under monitoring, as well as number of measurements.
Transmitters testsTransmitters can be verified using user procedures. 20 procedures can be stored as well as test results. Deviation curves are displayed. Edition of comprehensive test reports.
Switch testIn temperature or pressure mode, CALYS 150 can control electronic thermostat and pressostat trigger levels.
Ramps generationStarting, ending and length time values of simple or cyclic ramps can be set to do simulation. Number of ramps can also be adjusted in case of cyclic ramps for any signals.
Steps simulation2 modes are available:

  • Program mode: Starting value, number of steps and the length time have to be set
  • Manual mode: User has about a hundred preset values

In current simulation, user will have some additional preset values in function of range and according to 0%, 25%, 50%, 75% and 100% from selected gauge. Choice is done between gauges: 0-20 mA: linear or quadratic 4-20 mA: linear or quadratic

SynthesizerWith 100 values manually set, CALYS 150 enables users to draw a generation curve.
Transmitter functionCALYS 150 is able to be used as a transmitter. Measurement input is copied on the output with scaling.
