Certification & Safety Statements for Sentinel™ LCT4
Special Conditions for Safe Use
• Consult the manufacturer if dimensional information on the flameproof joints is necessary.
• Follow the manufacturer's instructions to reduce the potential of an electrostatic charging hazard.
• Consult the manufacturer for genuine replacement flange fasteners. M10x35 hexagon socket cap screws of
ISO 12.9 DIN912 grade steel (zinc-plated) or better, with a minimum yield strength of 135,000 psi are acceptable
alternatives.
• The sensor body temperature code rating is dependent on the process temperature. It is assumed that the external
surface of the sensor body will be, at worst case, equal to the process temperature. In all cases, the electronics
assembly will be marked T6, as it will be locally mounted for process temperatures up to 85°C and will be remotely
mounted for process temperatures exceeding 85°C.
Markings
• Markings shall appear on the meter and flowcell, as shown below, for the AC and DC powered versions and the
