Comparable type in pressure-encapsulated design.
XA8 01 04 / XA8 01 041    EEx de IIC T6
(ATEX in preparation)

Rod extension for type A 01 04
Where the mounting conditions or the operating differential require, the level switch can be equipped with rod extensions G1 or G2. For vertical mounting, rod extension G3 is used.


 

 

 

 

Type A 01 090 to A 01 095
With adjustable operating differential for 2-point operation, e.g. pump control.

Nominal pressure PN 25, max 25 bar at 300oC
Operating temperature 0 to 300oC
Ambient temperature 0 to 70oC
Density of liquid min. 0.8 kg/dm3
Operating differential adjustable, see PDF data sheet
Wetside material Stainless steel (CrNiMo)
Flange material Stainless steel (CrNiMo)
Switch housing material Sea-water resistant die-cast aluminium
Flange dimensions 92 x 92 mm (hole circle: 92 mm)
Switch element Microswitch, contacts (SPDT)
Switch rating 5A/250 VAC, 5A/30 VDC
Enclosure IP 65

Comparable type in pressure-encapsulated design.
XA8 01 090 / XA8 01 095 EEx de IIC T6

Adjustment of the operating differential
The operating differential can be adjusted by inserting pegs in the adjustment block. With type A 01 093 operating differentials of up to 557 mm can be attained.


 

Type A 01 140 and A 01 141
Vertical mounting, for use as limit/alarm function or as pump control (2-point control).

Nominal pressure PN 16, max 16 bar to 300oC
Operating temperature 0 to 300oC
Ambient temperature 0 to 70oC
Density of liquid min.  
   pump control 0.45 kg/dm3
   alarm 0.30 kg/dm3
Operating differential  
   A 01 140 12 to 1340 mm
   A 01 141 12 to 2840 mm
Wetside material Stainless steel (CrNiMo)
Flange material Stainless steel (CrNiMo)
Switch housing material Sea-water resistant die-cast aluminium
Flange dimensions 92 x 92 mm (hole circle: 92 mm)
Switch element Microswitch, contacts (SPDT)
Switch rating 5A/250 VAC, 5A/30 VDC
Enclosure IP 65

Adjustment of the operating differential
The required operating differential is attained by fixing stop collars on the rod. The alarm function or pump control is set by means of the counterweight.
