B: Probe Cable Length

00 Probe cable not required

05 0.5 m (20 in)

10 1.0 m (39 in)

12 12.0 in

18 18.0 in

24 24.0 in

30 30.0 in

36 36.0 in

C: Standoff Adapter

D: Probe Penetration

15 Minimum length 1.5 in (38 mm)

75 Maximum length 7.5 in (191 mm)

Recommendation ：

Order in increments of 0.5 in (13 mm)

Examples :

1.5 in (38 mm) = 15   No standoff adapter = 00

10 Minimum length 1.0 in (25.4 mm)

Other

Recommendation : Order in increments of 0.1 in (3 mm)

Examples :

3.7 in (94 mm) = 037

22.4 in (569 mm) = 224

Probe P/N and S/N may be displayed on a flag label for some combinations of the C plus D options where only a small section of the probe cable is visible.

For probe penetration lengths between 1.0 and 2.0 inches, it may be necessary to counter bore the machine case to reduce probe side view or rear view effects.

If you select a probe penetration length (C plus D) greater than 300 mm (12 in), you must add sleeve

support near the probe to prevent resonance from occurring.

Adjustment range of probe penetration option D is 13 mm (± 0.5 in).

E: Fittings

00 Without fittings

01

One 3/4-14 NPT explosion-proof fitting

One 3/4-14 NPT plug

02 Two 3/4-14 NPT explosion-proof fittings
