Druck MCX II Documenting Process Calibrator
A CALIBRATION WORKSHOP IN A SINGLE INSTRUMENT
The Druck MCX II portable documenting calibrator is the most
comprehensive field calibration tool available. It is the culmination of
many years combined field experience with the Druck and Unomat series
of portable pressure, temperature and electrical calibrators. Designed for
field use, this rugged, self-contained, battery powered package simulates and
reads RTD’s, thermocouples and resistance, as well as sourcing and reading
milliamps, millivolts, volts and frequency. With interchangeable single and dual
sensor pressure modules over 90 input and output ranges are available.
The MCX II saves time and money with the calibration, maintenance and
commissioning of instrumentation for process plants, production lines, utility
processing and distribution by:
• Reducing the burden imposed by quality systems such as ISO 9000.
• Reducing calibration, maintenance and commissioning time.
• Reducing documentation time and errors
• Replacing several standard test instruments.
• Reducing test instrument calibration costs.
• Minimizing down time and maximising efficient field usage.
• Input/output mA
• Input/simulate 12 types of T/C
• Input/simulate 9 types of RTD
• Input/output frequency and pulse
• Simulate transmitter input and measure transmitter output
• Input/output mV/V
• Input/output resistance
• Measure pressure: -14.7 to 5000 psi
• Test switches: captures values on contact change
• Trim smart HART transmitters
For example, a typical thermocouple transmitter calibration can take one
hour using a mV source, look-up tables and a milliammeter. In just five minutes
the MCX II can make an automatic calibration and document the results while
virtually eliminating human errors. A PCMCIA memory card provides data
storage and gives total flexibility to suit different working practices. By simply
exchanging PCMCIA cards, the MCX II can remain permanently in the field and
when compared to serial data transfer methods this can save one to two hours
a day. With a single item to calibrate the cost of re-calibration is reduced and the
inconvenience of down time is minimized.
HART® communicator for SMART transmitters
The HART® communicator allows digital field adjustment of smart transmitters.
Typical adjustments to sensor and analogue trims can take up to 40
minutes using conventional test equipment and a hand held communicator.
With a single MCX II this time can be reduced to less than 10 minutes,
including a fully documented calibration.

Easy to use
The multi-lingual user interface is an easy to use Input/Output
menu with dual parameter readout. The Input and Output connectors are
standard 4mm gold plated sockets which are separated and clearly labelled.
The rugged impact resistant enclosure is surrounded by a durable protective
carry case which allows access to all the instrument features and provides
convenient pockets for storing test leads and accessories. Whether the
MCX II is horizontal orvertical the rotatable display provides the optimal
viewing angle. On the bench, test leads and pressure modules connect to
the front face. In the field, with the MCX II held vertically by the wide neck strap,
the connections are made to the rear face. With safety a major design concern,
these features reduce the possibility of dropping equipment as the operators hands
are kept free.
The MCX 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 input and output
values in large clear digits with all applicable information such as the
units of measurement and range. Using the rotating display, the rear
face electrical connectors and wide neck strap, the instrument can be
safely worn around the neck or fastened to a suitable pipe or valve.
This leaves the operators hands free at all times and prevents
dangerous dropages. The easy to operate menu driven software
enables the MCX II to be set-up very quickly. Simply scroll
through the input and output menus to select the required parameters.
Operating and connection errors such as loop resistance mismatch and
cold junction temperature sensor absence are reported. The
KEYSTROKING memory enables instant recall of previously stored
user tests.
