The stainless steel shock-resistant bimetallic thermometer is a temperature measurement instrument specially designed for harsh industrial environments, especially suitable for applications with vibration, corrosion, and explosion-proof requirements.

Core Structure and Key Components
  • Bimetallic Temperature Sensing Element: A combination of nickel-chromium alloy and iron-nickel alloy, with a temperature range of -50 to 800°C, determining the basic temperature measurement accuracy.
  • Stainless Steel Components:
    • Housing: 304/316L stainless steel, resistant to corrosion and impact, with protection grade IP65 to IP67.
    • Protective Tube: 304/316L stainless steel (standard) or Hastelloy (for highly corrosive environments), with a wall thickness of 3 to 5mm and a pressure resistance of ≤25MPa.
  • Shockproof Mechanism: Filled with silicone oil or glycerin (damping medium) in the dial, and shockproof washers added to the gear transmission mechanism, with a vibration resistance level of ≤5g (industrial grade) and ≤10g (enhanced grade).
  • Display Module: Pointer type (dial diameter φ60 to 150mm, accuracy 1.0 grade), digital display type (LCD/LED screen, resolution 0.1°C, accuracy 0.5 grade), and the digital display model supports battery or external power supply.
  • Connection Method: Threaded connection (M27*2, G1/2"), flange connection (DN25/DN40), suitable for different pipeline installation requirements.
Main advantages:
  • Stable reading: Even in a strongly vibrating environment, the pointer remains steady without violent shaking, making it easy to observe and record.
  • High reliability: It effectively prevents mechanical wear, pointer detachment or transmission mechanism damage caused by vibration, with a low failure rate.
  • Wide environmental adaptability: It possesses multiple capabilities such as corrosion resistance, vibration resistance, and pulse shock resistance, making it an ideal choice for heavy industrial environments.
  • Long service life: Its robust structure and shock-resistant design ensure a long lifespan even under harsh working conditions.
  • High safety: With a fully sealed structure and a high protection level (typically IP65 or above), it is dust-proof and water-resistant.
Selection Points
  • Vibration level: Clearly define the vibration frequency and amplitude on site to ensure that the selected instrument's shock resistance meets the requirements.
  • Range and accuracy: Choose the appropriate range and accuracy grade suitable for the process temperature.
  • Material: Confirm the stainless steel grade (304 or 316). For highly corrosive environments, 316L or higher grade stainless steel may be required.
  • Installation interface: Select the appropriate thread specification (such as M27*2, G1/2", NPT 1/2") and the insertion depth of the temperature sensing tube.
  • Dial size and direction: Based on the observation distance and space constraints, choose the appropriate dial diameter and installation direction (axial, radial, universal type).
  • Protection grade: Confirm the IP protection grade, such as IP65 (resistant to water spray), IP67 (resistant to short-term immersion), etc.
Typical application scenarios
  • Pumps, compressors, fans: These rotating equipment are themselves strong sources of vibration.
  • Engine rooms of ships: Continuous engine vibration and marine corrosive environment.
  • Petrochemical facilities: Pipelines and equipment with fluid pulsation and chemical corrosion.
  • Power industry: Boiler, turbine auxiliary systems, etc.
  • Heavy machinery: Injection molding machines, hydraulic systems, etc.
  • Pipeline systems with water hammer phenomenon.

Stainless steel shock-resistant bimetallic thermometers are a symbol of toughness and reliability in industrial measurement. Through two core technologies - a fully stainless steel casing and oil-filled shock absorption - they perfectly address the core difficulty of "unclear readings and easy damage" of thermometers in harsh working conditions. If the equipment you need to measure experiences vibration, pulsation, or is in a corrosive environment, choosing a high-quality shock-resistant bimetallic thermometer is a wise and necessary investment, ensuring you obtain long-term, stable, and reliable temperature data.
