Portable documenting calibrator

TRX II

A new standard for portable multifunction calibrators The Druck TRX II portable documenting calibrator is the

culmination of many years of combined field experience with the Druck and Unomat series of calibrators.

This one self-contained, battery powered package simulates and measures RTD’s,thermocouples and resistance, as well as sourcing and reading milliamps, millivolts, volts and frequency. The rugged design includes an impact resistant enclosure which is fastened to the carrying case for convenience and safety. Dedicated alphanumeric and documenting keypads surround a large LCD panel with dual readout and backlight. Connectors for source and measure are kept separate and a 24V output is provided for loop power.

The TRX II’s extensive measurement capabilities can include pressure measurement by connecting Druck pressure sensors which have been digitally characterized to give high accuracy.

This highly accurate and easy to use documenting calibrator provides improved data quality and quicker calibration time since data can be uploaded and downloaded via the PCMCIA card or the RS232 interface.

High performance and multi-functional

Remote pressure sensors: 1 to 10,000 psi including gauge, absolute

and differential Loop power: 24 Vdc Data storage: 1 Mbyte and 2 Mbyte PCMCIA cards Data transfer: RS 232 or PCMCIA card

Simple to operate

The combined Druck and Unomat knowledge of customer needs, and innovative design, results in a high performance, yet easy to operate, multi-function documenting calibrator.

The key to the simple operation of the TRX II is the structured menu. Input and output readings are displayed simultaneously for test modes such as T-I and P-I, allowing quick comparison of the values. Used in conjunction with Linkpak-W calibration software, or Intecal-W database software, the TRX II will perform automatic calibrations from predefined procedures, calculating and reporting errors to the operator and storing the results on a PCMCIA card. This intuitive approach, whether used manually or automatically, ensures correct set up for the job at hand and improves working efficiency and data accuracy.

The TRX II provides simple and flexible data transfer to fit in with most working practices. Information can be reviewed on screen or transferred to and from the TRX II using the RS 232 interface. Alternatively, without docking the instrument to a PC, data can be transferred by exchanging PCMCIA cards.

The operating system works in several languages and provides scaling, step and ramp features for calibration and maintenance. The TRX II, which includes extensive self-test routines, can be relied upon time and time again for field calibration in extreme conditions.

The TRX II has been designed for ease of use while meeting a wide range of application needs including calibration, maintenance and commissioning. The dual parameter display shows the measured and sourced values in large clear digits with all applicable information such as the units of measurement and range. With safety in mind, construction of the shoulder strap allows hands free operation while maintaining display visibility.

Measure/source mV/V ! Measure/source resistance ! Measure pressure: -14.7 to 10,0 00 psi ! Test switches: captures values on contact change

Easy to operate

The easy to operate menu driven software enables the calibrator to be set up very quickly. Simply scroll through the menus and select the appropriate parameters.

Operating and connection errors such as loop resistance mismatch and cold junction temperature sensor absence are reported. The

memory enables instant recall of previously stored user tests.

TRX II

Applications

MULTIFUNCTION PORTABLE CALIBRATOR

TEMPERATURE SENSOR SIMULATION AND LOOP CHECKING

The auto step and ramp modes enable a single technician to test and commission control loops. The calibrator is left to generate a pre-programmed output, while the technician checks the signal further down the loop.

End to end control loop performance can be checked with one instrument by simulating a temperature signal at the start of the loop.

When troubleshooting apply a three step approach.

Step one:

Measure the sensor output to confirm correct connection and operation.

Step two:

Check and calibrate the transmitter by simulating temperature signals and measuring the corresponding mA outputs.

Step three:

Feed the loop with a mA signal and check wiring and instrumentation further down the line.

CALIBRATION FOR ISO 9000

Direct connection of thermocouple compensation wires eliminates the need for special connectors and reduces additional cold junction errors. This is the most reliable and accurate method of monitoring cold junction temperatures in a portable field calibrator.

In calibration mode the display shows all the required information. Both mV and mA values are displayed in °F for easy comparison, along with the calculated error expressed as % of span or reading.

The TRX II will simulate the temperature signal to the transmitter to be calibrated and will simultaneously measure and display the output. A 24 volt power supply is provided for stand alone operation.

TEMPERA TURE TRANSMIT TER SIMULATION AND CALIBRA TION

The connection of 2, 3 and 4 wire RTD‘s is detected automatically, a feature unique to Druck portable field calibrators.

Dedicated keys for documenting field calibrations eliminate human errors and are available as standard. The ’AS FND’ (as found) and ‘AS LEFT’ keys start the respective procedures for storing calibration data which can be recalled using the ‘VIEW’ key.

Optional PCMCIA cards represent the most efficient data transfer media. Docking of the calibrator with the PC is unnecessary as a card containing calibration data can be exchanged for another containing new procedures/work orders, enabling technicians and calibrators to spend more time in the field.

Data is transferred to the PC from the PCMCIA card or the RS 232 interface for analysis, certificate printing and archiving. Exporting facilities are provided for wordprocessor and spreadsheet applications or in-house maintenance systems.

Remote pressure sensors offer a cost effective means of expanding the capabilities of the TRX II, for example:

n Calibration of pressure transmitters n Testing pressure switches n For differential pressure applications n For flow measurement calibrations

The capability of the TRX II can be extended by adding up to 8 external pressure sensors (connected one at a time). With ranges from 1 to 10,0 00 psi and all welded stainless steel and Hastelloy construction, sensors can be chosen to suit many applications. Remote pressure sensors require a mating cable approximately 4.5 feet in length. One end connection interfaces with the remote pressure sensor electrical input and one end mates with the TRX II remote pressure sensor electrical input (please refer to Option B2). Druck has applied the latest technology and production techniques to develop these sensors which are digitally corrected for nonlinearity and temperature effects.

Specifications

Over 50 sensor ranges are available including gauge, absolute and differential versions and with accuracy better than 0.05% FS, even the most up to date pressure instrumentation can be maintained and calibrated.

OPTIONS

(A1) Linkpak-W calibration software (P/N LINKW)

Linkpak-W calibration software has been developed to help meet the growing demand on industry to comply with quality systems and calibration documentation. Test procedures are created in a Windows based application and devices due for calibration are reported and grouped into work orders for transfer to one of three calibrators, the DPI 605, TRX-II and the MCX. Calibration results, including files from the DPI 610, are uploaded to the PC via the RS 232 interface or PCMCIA card, for analysis and to print calibration certificates.

(A2) Intecal-W calibration database software (P/N INTEW)

Intecal-W Windows based soft ware builds on the basic concept of Linkpak-W supporting both portable field calibrators and on-line workshop calibrators. Manual data entry is also a key feature for recording data. Intecal-W is an easy to learn and easy to use calibration management software for process plants, workshops, contractors, manufacturers and service companies. It offers high productivity of calibration scheduling, calibration work and documentation. Device information, calibration procedures and calibration results are stored in an instrument database and multiple databases can be created for organizing client accounts, processes or areas. Extensive management features are provided including a database search engine, time based calibration due queries and standard reports.
