Equipment and systems covered by this certificate are as follows

Smart temperature transmitter type LI-24ALW version Ex d are designed for temperature measuring in various industrial applications related to measurements, control and regulation. The transmitter basic components are enclosure and logic unit converting signal form the measuring sensor to output signal. LI-24ALW transmitters can be provided with temperature sensors installed directly to the transmitter enclosure or temperature sensors installed with the connection cable. Enclosure of the LI-24ALW transmitter is made of high pressure die-cast aluminium alloy or stainless steel. The housing consists of a main enclosure and two screwed access covers (for the display and electrical connection terminal) Cover for the display has a window. The enclosure is provided with two openings with M20x1,5 or ½” NPT.

  • Temperature class transmitter with temperature sensor installed directly (T* for gas) or the maximum surface temperature (T* for dust) depends mainly on the process temperature (temperature-controlled medium) and methods of installation on site. Installation details are given in manufacturer's manual.
  • Some of the permitted gaps in flameproof joints are smaller and width of the flameproof joints are greater than the one specified in table 1 EN 60079-1. The relevant information for the user are included in the manual.
