Double rod probe 11362Z

Summary

Product identification

• Product Name: Double rod probe 11362Z
• Type: Process instrument, sensor, transmitter, or analyzer for level measurement.

Application

These probes are designed for:

• Limit Detection: Accurate detection of fill levels or overspill protection in plastic or non-conducting vessels.
• Two-point Control: Can be used in vessels with electrically conducting walls.
• Corrosive Liquids: Suitable for aggressive products due to highly corrosion-resistant materials for probe rods and process connections.
• Explosion Hazardous Areas (11362 Z version):
  • Zone 0
  • Waste water plants (sometimes regarded as Zone 0)
  • Overspill protection for water-polluting liquids (WHG).

Operating limits

• Plastic process connections:
  • Operating pressure: –0.2...+0.2 bar
  • Temperature: –25°C...+80°C
• Metal process connections: Operating pressure and temperature depend on the specific connection (refer to drawing in the original document).
• EW 11 Z electronic insert: Maximum permissible operating temperature is 80°C.
• PP process connections (DN 50, DN 80, DN 100, DN 150): Maximum 1.5 bar abs.
• PP process connections (2", 3", 4"): Maximum 22 psia.

Feed water

The probes are designed for various liquid applications, including those with potentially conductive deposits on the probe insulation.

Electrical

• Electronic Insert: The probe can be supplied with an integrated EW 11 Z electronic insert for cable monitoring or an integrated terminal block.
• Function Monitoring: The EW 11 Z can be used for continuous cable monitoring with maximum limit indication when paired with a Nivotester FTW 325/470 Z/570 Z/520 Z, which is required for overspill protection.
• Explosion Hazardous Area Use: The probe is not permitted for use in explosion hazardous areas when connected to the Nivotester FTW 420.
• Ground Connection: A good ground connection between the probe head and the vessel is important.

Mechanical / hydraulic

• Probe Rods & Process Connections: Made from highly corrosion-resistant materials.
• Variable Process Connections:
  • Thread G 1 ½ A (parallel)
  • Thread 1 ½“ NPT (tapered)
  • Flanges conforming to DIN (DN 40 to DN 200, PN 16 or PN 40)
  • Flanges conforming to ANSI (1 ½“ to 4", 150 psi or 300 psi)
• Installation:
  • Generally installed vertically.
  • Compact probes up to approx. 300 mm can be installed at any orientation.
  • A support is required for probes subjected to high lateral loads.
  • For liquids tending to deposit conductive layers, the final spacer should be moved at least 100 mm from the end.
  • If the probe needs to be shortened, ensure the insulation is not damaged and feed-throughs are not subjected to mechanical force. Remove rod insulation at the tip by at least a further 20 mm.
• Probe Length (L): 100 mm ... 4000 mm.
• Materials:
  • Spacer material: PFA
  • Seal (thread version): elastomer/fibre, non-asbestos
  • Rod materials available include 316Ti, Alloy B, Alloy C4, Titanium, Tantalum, Monel.
• Insulation Lengths (Standard): Dependent on probe length (L) and whether EW 11 Z or terminals are used.
• Dimensions: Refer to the drawing in the original document for detailed dimensions.
