• The maximum permissible pressure pmax of the transmitter may not be
exceeded.
• The temperature of the medium in contact with the transmitter may
not exceed +80°ÀC.
• Avoid formation of ice on the process input of the transmitter because
this could damage the diaphragm.
• Prevent soiling of the transmitter input.
• Avoid obstruction to the vent pipes in the special cable (influences the
measuring accuracy).
