• Light energy industry
• Food industry
• General industrial services

Material

• Wetted parts: SS 316L/1.4404 or SS 316Ti/1.4571

Mechanical / hydraulic

• Thermowell Pipe Diameter: 9 mm, 11 mm, or 12 mm
• Tip Types: Straight, tapered, or reduced (stepped)
• Weight: 0.5 to 2.0 Kg for standard options

Operating limits

• Process Temperature:
  • SS 316L/1.4404: -200 ÷ 600°C
  • SS 316Ti/1.4571: -200 ÷ 800°C
• Maximum Process Pressure (for 9 mm pipe):
  • 50 bar at 20°C
  • 33 bar at 250°C
  • 24 bar at 400°C
  • See the official PDF for exact tabulated values (Figures 2 and 3 provide pressure/temperature drawings).
• Maximum Flow Velocity: Decreases with increasing exposed length. See the official PDF for exact tabulated values (Figures 2 and 3).

Installation

• Can be mounted on pipes, vessels, or other plant parts.
• Interface components for process connections and gaskets are not provided.
• Recommended immersion length (L) of at least 80-100 mm for accuracy, especially with large temperature differences.
• For small pipes, the tip should reach or exceed the duct's axis line.
• For food industry use, the rule h <= d/2 is recommended.
• Wetted materials (SS 316L/1.4404, SS 316Ti/1.4571) tolerate common corrosive media.

Process connection

• Standard Types:
  • M20x1.5
  • G 1/2” DIN 43772 (DIN 3852 form 2G/3G)
  • G 3/8”, G 1/2” and G 3/4” BSP cylindrical
  • 1/2” and 3/4” NPT
• Other versions available on request.
• Engaging lengths (C mm) for standard connections are listed in the document (e.g., 1/2” NPT = 8 mm, G 1/2” DIN = 15 mm).
• Customizable immersion lengths are available.
• Surface finishing (Ra) is 0.8 μm.

Certificates & approvals

• PED Approval: Compliant with Pressure Equipment Directive (97/23/CE). Marking not mandatory for generic applications.
• Material Certification: 3.1.B (EN 10204) available, referring to wetted parts. Traceability guaranteed.
• Tests:
  • Pressure tests performed at ambient temperature per DIN 43772.
  • Liquid penetrant (dye) test verifies weld integrity.
