AMETEK ATMi Series Crystal ATMi Intrinsically Safe Temperature Module Instruction Manual

AMETEK ATMi Series Crystal ATMi Intrinsically Safe Temperature Module

Overview

INTRODUCTION

The Crystal ATMi series of intrinsically safe temperature modules allow you to add temperature measurement capability to your HPC50 pressure calibrator. The ATMi uses the same reliable, high accuracy, digital temperature compensated technology found in other Crystal instruments, housed in a rugged enclosure with a selectable length cable to connect to your HPC50 calibrator. Two ATMi modules can be connected to a single HPC50 calibrator.
Note: Currently, the HPC50 is the only Crystal calibrator supported by the ATMi pressure module.
Note: This manual includes information on the ATMi modules only. For details on the operation of the HPC50 Series, please refer to the User Manual.

What’s Included
Each unit includes an ATMi temperature module, an interface cable of your choice (1, 3, or 10 meter), ISO 17025 Accredited Calibration Certificate, NIST traceable calibration certificate, and AMETEK product CD. Crystal Engineering calibration facilities are A2LA accredited, (#2601.01) which is internationally recognized by ILAC. See ordering information information below for probe options.

CERTIFICATIONS

We declare that the ATMi is in accordance with the Electromagnetic Compatibility Directive per our declaration(s).

This HPC50 is approved for use as a portable test instrument for Marine use and complies with DNV GL Rules for Classification of Ships, High Speed & Light Craft, and Offshore Units.

The proper selection of the RTD sensing element is very important as the error associated with this device is the majority of the overall system measure-ment uncertainty. IEC 751 is the standard that defines the temperature versus resistance for 100Ω, 0.00385 Ω/Ω/°C platinum RTDs. IEC 751 defines two classes of RTDs: Class A and B. Class A RTDs operate over the -200 to 630°C range versus -200 to 800°C for the Class B elements. For example, the Class A uncertainty is about half that of the Class B elements as illustrated in the following table.

Support

CALIBRATION

If adjustment is required, we recommend returning the ATMi to the factory. Factory service offers benefits you won’t find anywhere else. Factory calibra- tion tests your ATMi utilizing NIST traceable standards, resulting in calibration certificates that provide performance data and uncertainties. Our calibration facilities are A2LA accredited (cert #2601.01) to ISO 17025:2005 & ANSI/NCSL Z540-1-1994. A2LA is internationally recognized as an accreditation body by the International Laboratory Accreditation Cooperation, ILAC. Furthermore, upgrades may be available to add or enhance operating features. We designed the product to last, and we support it so that you can get the most from your investment.

Under normal operating conditions, we recommend the ATMi be calibrated on an annual basis. Your quality system may require more or less frequent calibra- tion, or your experience with the gauge, or operating environment may suggest longer or shorter intervals. There are no internal potentiometers. The ATMi has a “span factor” (userspan), set to approximately 1 (as shipped from the factory). As components age this may need to be changed to a value slightly higher or lower, to slightly increase or decrease all readings. This adjustment can be made with a computer through our free CrystalControl software.

WARRANTY

Crystal Engineering Corporation warrants the ATMi (Advanced Pressure Module) to be free from defects in material and workmanship under normal use and service for one (1) year from date of purchase to the original purchaser. It does not apply to batteries or when the product has been misused, altered or damaged by accident or abnormal conditions of operation. Crystal Engineering will, at our option, repair or replace the defective device free of charge and the device will be returned, transportation prepaid. However, if we determine the failure was caused by misuse, alteration, accident or abnormal condition of operation, you will be billed for the repair.

CRYSTAL ENGINEERING CORPORATION MAKES NO WARRANTY OTHER THAN THE LIMITED WARRANTY STATED ABOVE. ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE, ARE LIMITED TO A PERIOD OF ONE (1) YEAR FROM THE DATE OF PURCHASE. CRYSTAL ENGINEERING SHALL NOT BE LIABLE FOR ANY SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, WHETHER IN CONTRACT, TORT OR OTHERWISE.

Note: (USA only) Some states do not allow limitations of implied warranties or the exclusion of incidental or consequential damages, so the above limita-tions or exclusions may not apply to you. This warranty gives you speciÿc legal rights and you may have other rights which vary from state to state.
