The PT100-8’s adjustable insertion depth and versatile fitting options make it exceptionally well suited to applications where precise immersion control is required or where the same sensor model must serve multiple installation points with varying wall thicknesses or pipe diameters.

• Industrial Pipelines and Vessels. The compression fitting allows the probe to be inserted to the exact centreline of a pipe or the optimal depth within a vessel, maximising measurement accuracy regardless of pipe diameter. The liquid-tight seal ensures reliable performance even under moderate process pressures.
• HVAC and Air Handling. The sensor can be inserted into air ducts, plenums, and fan coil units at any depth to capture representative air temperature readings. Its adjustability is particularly valuable during commissioning, where optimal probe placement may need to be determined empirically.
• Plastics and Rubber Processing. In injection moulding and extrusion, the ability to position the sensing tip at a precise depth within a heated barrel, manifold, or mould cavity is critical to process consistency. The PT100-8 can be adjusted and locked without removing the fitting from the equipment.
• Food and Beverage Processing. The stainless steel probe and waterproof option meet the hygienic requirements of food-contact applications. The sensor is suitable for monitoring liquid temperatures in mixing tanks, pasteurisers, and CIP (clean-in-place) circuits.
• Chemical and Pharmaceutical Processing. The PTFE-insulated cable and choice of Teflon lead wire provide chemical resistance for use in environments where aggressive vapours or cleaning agents are present. The adjustable depth allows the sensing element to be positioned away from vessel walls and into the bulk process fluid.
• Laboratory and Test Equipment. Researchers and test engineers benefit from the ability to reposition the probe without disturbing the process seal, enabling multi-point temperature profiling within a single installation port.
• OEM Integration. The compact compression fitting and range of metric and imperial thread options allow the PT100-8 to be integrated into custom machinery and equipment during the design phase, with the adjustable depth providing tolerance for manufacturing variation in housing dimensions.
