The manufacturer disclaims all responsibility in case of damages caused by the improper use of the product and by the non-respect of the instructions reported in this manual.
Follow carefully the specific safety rules in case of measuring oxygen pressure, acetylene, inflammable or toxic gas or liquids.
Disconnect the instruments only after depressurization of the system.
The process fluids residuals in the disassembled instruments could affect people, the environment and the system. It is highly recommended to take proper precautions.
Before installation be sure that the right instrument has been selected following the working conditions and in particular the range, the working temperature and the compatibility between the material used and the process fluid.
This manual does not concern the instruments conforming to standard 94/9/CE (ATEX).
The product warranty is no longer valid in case of non-authorized modifications and of wrong use of the product.
The user is totally responsible for the instrument installation and maintenance.
Handle and carefully stock the instrument used for toxic or inflammable liquids measurement
The transmitter metal case should always be connected to ground through the process connection thread in order to protcct it from disturbances due to electromagnetic fields or electrostatic charges.
If it wouldn’t be possible to do so connect the transmitter to ground through the connector and the cable s Before installing electrical instrument safely and securely into a plant or a system the user should verify the instrument suitability to the plant characteristics and the correct installation. After installation the user should verify that the instrument is not exposed to any source of heat exceeding the established ambient limits.
Secure the instrument thread through a special key/wrench on the process connection hexagon without grasping the case by the hands.
Secure the instrument thread through a special key/wrench on the process connection hexagon (20...30Nm). The correct torque depends on the type of process connection and the type of seal used (form and material).
If the connection thread is conical the instrument is tightened through a simple screwing on the plug. In order to improve the thread tightness it is recommended to place a PTFE layer on the male thread.
If the instrument is equipped with a fluid diaphragm seal the connection should be clamped on the diaphragm otherwise the calibration could be compromised.
Instruments showing symbol.
Instruments with process connection DIN 11851 must be installed with special adapter SKS.
Instruments with process connection ISO 2853 (IDF/ISS) must be installed using gaskets with supporting ring according to the above mentioned standard.
