* - Only probe length should be in zone 0 (20), while connection head is in zones 1(21), 2 (22).

Design features: The model has a mobile threaded connection and a flameprood aluminum head. It can be supplied with Gz-3, Gz-9 or Gz-10 thermowells.
Aluminum head is connected to the controller by means of flexible cable through flameprood cable glands. There are two cable glands available: unarmoured and armoured glands.

Flameproof Unarmoured Cable Gland (N)	Flameproof Armoured Cable Gland (A)

N8 - Cable OD 3.0-8.0 mm N12 - Cable OD 7.5-11.9 mm N14 - Cable OD 11.0-14.3 mm	А12 - Cable OD 5.5-12.0 mm А20 - Cable OD 12.5-20.5 mm

**Probe Standard Lengths and Diameters**
Probe Length, L	60, 80, 100, 120, 160, 200, 250, 320, 400, 500, 600, 800, 1000, 1500, 2000 mm
Outer Length*	70, 120 mm
Probe Diameter	6, 8, 10 mm

* - Outer length is the distance between a flange and a protection head

Note: The protection head should be at the temperature range from -40 to 80 °C for armoured cable gland, and from -40 to 100 °C for unarmoured cable gland. To ensure this condition, it is sometimes necessary to order a longer probe or outer length to take a vulnerable part out of a hot zone.
