Honeywell 4905 Industrial Electrolytic Conductivity Cells

Industrial Electrolytic Conductivity Cells
4905

Constructed of PES and Ryton for high corrosion resistance, 4905 Series cells can be supplied with nickel, platinum or Monel (depending on cell constant) electrodes, and will provide continuous reliable measurements at temperatures up to 140°C at pressures up to 250 psi.

For insertion applications, the 1” NPT male thread permits installation in a pipe or tank, for flow applications, the cell can be installed directly into a process stream, or used with a separately ordered 276127 Flow Chamber in a bypass stream. For immersion applications, ½” rigid or flexible plastic pipe can be added to the top of the cell: up to 19’ (5.8m) for the 20’ cable; up to 49’ for the 50’ cable. When used in immersion applications, temperature must not exceed 85°C.

Approvals Manufactured to comply with ASME boiler and pressure vessel code Section VIII, Div. 1, UG-101. CRN #0F11607-5C
Cell Constants 4905 Model: 0.01, 0.1, 1.0, 10, and 50 cm-1
Electrode Material Nickel, Monel or platinum, as specified. Constants 10 and higher are platinized.
Leadwire 4905: PVC-covered 22- gage shielded cable 20’ or 50’ long, as specified. If more than 50’ is required, select either the cast aluminum junction box head option or select the 50’ option and the separate 31316260 cast iron junction box and additional length of leadwire as necessary.
Electrical Connections 6 leads with integral Automatic Temperature Compensator. Integral cable – 6 leads with integral Automatic Temperature Compensator Quick disconnect option – mating head with cable must be purchased from Honeywell. This option cannot be used in immersion applications.
Pressure 250 psig @ 140°C (284°F) maximum
Temperature 140°C (284°F) maximum continuous (the temperature limit for the A.T.C. accuracy may be lower than the cell’s material-of-construction temp. limit).
Mounting 1” NPT male
Insertion Depth 114 mm to 175 mm (4.5” to 6.9”) depending on cell constant; 112 mm or 224 mm (4.4” or 8.8”) additional depth available on special order.
Wetted Materials Cell: polyethersulfone/Ryton
Electrodes: Nickel, Platinum, or Monel (as specified)
Weight Approximately 0.45 kg (1 lb.)

Insertion 
The 1” NPT male thread permits installation in a pipe or tank; the cell can also be used as a laboratory dip-type for batch sampling.

Immersion 
1/2” rigid or flexible plastic pipe can be added to the top of the cell. Temperatures must not exceed 85°C. Up to 5.8 m (19’) for the 20’ cable, up to 49’ for the 50’cable.

Flow 
The cell can be installed directly into a process stream, or used with a separately ordered 276127 Flow Chamber in a bypass stream.

Flow Velocity 
Maximum 10 ft./sec (3.0 m/sec)
