Component Specifications

Definition
A precision-engineered mechanical interface component designed to securely connect sensing elements or probes to industrial machinery, instrumentation, or piping systems. Connection threads provide screw-type attachment with standardized pitch and diameter, while flanges offer flat-faced bolted connections with gasket sealing. This component ensures reliable mechanical coupling, proper alignment, and environmental sealing for accurate sensor operation in industrial environments.
Working Principle
Mechanical fastening through threaded engagement or bolted flange connection creates a secure, sealed interface between the sensing probe and its mounting point. Threads convert rotational force into linear clamping force, while flanges distribute load evenly across multiple bolts with gasket compression. Both methods maintain precise positioning, prevent vibration-induced loosening, and protect internal components from contaminants.
Materials
Stainless steel (AISI 304/316), carbon steel, brass, aluminum alloys, or specialized alloys for corrosive environments. Surface treatments include passivation, plating, or coating for corrosion resistance.
Technical Parameters
  • Thread Types NPT, BSP, Metric, UNF
  • Sealing Method O-ring, gasket, or metal-to-metal
  • Connection Size 1/4" to 2" typical

Frequently Asked Questions

What is the difference between NPT and BSP threads for sensor connections?

NPT (National Pipe Taper) threads are tapered and seal through thread deformation, common in North America. BSP (British Standard Pipe) threads can be parallel (BSPP) or tapered (BSPT), using sealing washers or O-rings, prevalent in Europe and Asia.

How do I prevent leakage in flanged connections for sensing probes?

Ensure proper gasket selection (material compatible with media), correct bolt torque sequence and values, flange face cleanliness, and alignment within specified tolerances. Regular inspection and maintenance are essential.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
