58 DigitalFlow™ GM868 Service Manual
Special Conditions for Safe Use
1. Consult the manufacturer if dimensional information on any flameproof joint is necessary.
2. Follow the manufacturer’s instructions to reduce the potential of an electrostatic charging hazard.
3. 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.
4. 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 worse case, equal to the process temperature (up to 140°C). 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 appear on the instrument label which identifies the product model, serial number, operating ranges,
hazardous area ratings, entry thread type, and warning and caution information.
EU / EEA Installation Compliance
The use of this apparatus is subject to the EU directive on minimum requirements for improving the safety and health
protection of workers potentially at risk from explosive atmospheres, Council Directive 1999/92/EC . The installer is
