Process connections

Flush diaphragm flanged seal (**) :

2in or 3in ANSI 150 to 300 RF

DN50 or DN80 DIN ND 16-40 Form C

Wafer seal (backup flange not supplied)

2in, 3in to ANSI; DN50, DN80 to DIN.

Electrical connections

Two 1/2 NPT or M20x1.5 or PG 13.5 or 1/2 GK threaded

conduit entries, direct on housing; straight or angle Harting

HAN connector and one plug, on request.

Terminal block

• HART version

Three terminals for signal/external meter wiring up to 2.5 mm

(14 AWG) and three connection points for test and

communication purposes.

• Fieldbus versions

Two terminals for signal wiring (bus connection) up to 2.5 mm

(14 AWG)

Grounding

Internal and external 6 mm

(10 AWG) ground termination

points are provided.

Mounting position

Transmitter can be mounted in any position but with a

maximum ± 1° from vertical.

Electronics housing may be rotated to any position. A positive

stop prevents over travel.
