Further requirements of the Directive apply to the manufacturing process and supply of this product. These are not covered by this certificate. 12. The marking of the product shall include the following: II 1 G Ex ia IIC T4 Ga -30°C = Ta = +85°C 13. Description of Equipment or Protective System The APT 500 Series level transmitters are designed for monitoring liquid levels and pressures, based on a micro-electro-mechanical (MEMS) piezo-resistive cell. The pressure measurement cell is isolated from the process by a diaphragm with an internal fluid fill transmitting the process pressure to it. Temperature compensation and zero correction are applied during manufacture by laser trimming of compensation resistors. The output from the measurement cell is converted by an internal circuit to a 4-20mA signal which is scaled to the user requirements. The sensor is fully encapsulated internally and may be manufactured from a choice of construction materials for the wetted parts. The model code is defined as follows: APT 500 – Non-Intrinsically Safe models APT 500/I – Intrinsically Safe, ATEX certification APT 500/X – Intrinsically Safe, IECEx certification The model code may be followed by other alpha-numeric characters, to define other features of the product. Entity Parameters: Ui = 28V Ii = 93 mA Pi = 0.7W Ci = 12nF Li=0 14. Report Number Intertek Report Ref: 103201808LHD-002, Dated: May 2018. 15. Special Conditions of Certification (a). Specific Conditions of Safe Use • Non-metallic parts on the exterior of the pressure transmitter may present an electrostatic charging hazard. Refer to warning marking and the manufacturer’s instructions for further guidance. • Where external parts of the pressure transmitter incorporate light metal components (i.e. in excess of 10 % in total of aluminium, magnesium, titanium and zirconium), the sensor must be protected from impact such that impact / friction sparks cannot occur, taking into account rare malfunction. (b). Conditions of Manufacture - Routine Tests • None 16. Essential Health and Safety Requirements (EHSRs) The relevant Essential Health and Safety Requirements (EHSRs) have been identified and assessed in Intertek Report Ref: 103201808LHD-002, Dated: May 2018. 17.
