ESI Pressure Transmitter/ Pressure Transducer Installation Guide

• Intended Use

  Please refer to datasheet, calibration certificate and installation instructions before starting installation.

  The Device must be used within the specified pressure range, temperature and supply voltage.

• Installation

  During Installation, please comply with the relevant national guidelines.

  Installer must be technically competent and familiar with pressure monitoring technology.

• Mechanical Installation

  Ensure system is not pressurised before installation.

  Ensure the measurement cell is not damaged before installation.

  Use the correct sized AF wrench on the hexagon with tightening torque in accordance with table 1. The customer must ensure that the pressure seal is suitable for the application.

  See tightening torque setting guidelines in table 1 below.

• Electrical Installation

  Remaining media in the pressure port may be hazardous so handle with care.

  Refer to product calibration certificate for wiring diagram.

  Ensure electrical connector and cable gland are securely fitted and sealed.

• Maintenance

  Recalibration interval depends on own industry guidelines.

  Do not insert pointed or hard objects in to the pressure port.

  Repairs must be carried out by manufacturer only.

• Removal/ End of Life

  Ensure system is de-pressurised before removal

  Remaining media in the pressure port may be hazardous so handle with care.

  Can be returned to factory at end of life for cleaning.

  * The torque values apply only to test conditions, and are a guide only. Tightening torques for installation depend on many factors including materials, lubrication, coating and surface treatment. If in doubt consult manufacturer.

  ** NPT threads need an additional seal to BS EN 751 (e.g. PTFE tape)
  *** Tightening torque and maximum pressure should be in accordance with high pressure pipe supplier’s documentation.

  Materials of the mating part should be selected to suit pressure and media requirements.
