Delta F Oxygen Cell
The Series 1 standard oxygen measurement probe is the Delta F Cell.
Overall oxygen content range is from 0 to 25%. You may choose
from seven standard oxygen ranges.The lowest standard range is 0 to
1/10/100 ppm, and the highest standard range is 0 to 25% oxygen. An
ultra-low range sensor that covers 0-500 ppb
v
and is sensitive to less
than 5 ppb is also available. The Series 1 also accepts oxygen inputs
from other GE Panametrics oxygen sensors.
If your application has a high concentration of acid-forming
components, GE Panametrics can supply a STAB-EL option for the
Delta F Cell. The STAB-EL option is specially designed to
effectively neutralize these components from the sample gas stream.
The Delta F Cell is available in a general purpose model with both a
top and bottom drain or only a top drain (see Figure 1-5 below). The
Delta F Cell is usually installed in its own sample system.The Delta F
Cell is available with VCR® fittings, mounted in a NEMA-4X
enclosure for weatherproof/corrosion resistant applications, or
mounted in a NEMA-7 enclosure for hazardous areas.
The Delta F Cell, when operated with a BASEEFA-approved
Series 1, is intrinsically safe (see Chapter 3, Specifications, of the
Startup Guide for BASEEFA certification numbers) and designed to
meet the requirements of IEC/CENELEC zone 0 areas.
The Delta F Cell, when used with a CSA-NRTL certified Series 1, is
intrinsically safe (see Chapter 3, Specifications, of the Series 1
Startup Guide for CSA-NRTL certification numbers) and designed to
meet the requirements of NEC C1.1, Div. 1, Groups A, B, C and D
hazardous areas.
