Industry-Verified Manufacturing Data (2026)

Sensor/Probe

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Sensor/Probe used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Sensor/Probe is characterized by the integration of Sensing Element/Tip and Probe Body/Housing. In industrial production environments, manufacturers listed on CNFX commonly emphasize Stainless Steel (e.g., 316L) construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A sensing element that detects and measures the level of liquids, solids, or slurries within a container or vessel.

Technical details and manufacturing context for Sensor/Probe

Definition
As a critical component of a Level Indicator system, the Sensor/Probe is the primary interface with the measured medium. It converts the physical property of the material level (e.g., presence, pressure, capacitance, ultrasonic echo) into an electrical signal that is transmitted to the indicator or controller for processing and display.
Working Principle
Operates based on a specific physical principle (e.g., conductive, capacitive, ultrasonic, pressure differential, float-based) to detect the interface between the material and air/vapor space, generating a corresponding signal proportional to the level.
Common Materials
Stainless Steel (e.g., 316L), PTFE (Teflon), Ceramic, Hastelloy
Technical Parameters
  • Probe length or sensing range, critical for determining the measurement span within the vessel. (mm) Standard Spec
Components / BOM
  • Sensing Element/Tip
    Directly interfaces with the process medium to detect the level based on the chosen physical principle (conductivity, capacitance, etc.).
    Material: Stainless steel, PTFE, ceramic
  • Probe Body/Housing
    Protects internal electronics, provides the process connection, and ensures mechanical integrity and sealing.
    Material: Stainless steel (e.g., 316), brass, plastic
  • Electrical Connection Head
    Houses the terminal block or connector for the output signal wires and may contain signal conditioning electronics.
    Material: Aluminum, plastic (e.g., PA)
Engineering Reasoning
0-1000 kPa absolute pressure, -40°C to 125°C ambient temperature
1500 kPa burst pressure, 150°C diaphragm material glass transition temperature
Design Rationale: Diaphragm plastic deformation exceeding 0.2% yield strain at 1500 kPa, polymer membrane degradation above 150°C
Risk Mitigation (FMEA)
Trigger Electrochemical corrosion at 6.5 pH fluid interface
Mode: Diaphragm pitting corrosion leading to 0.1 mm thickness loss
Strategy: 316L stainless steel diaphragm with 0.5 μm PVD ceramic coating
Trigger Capacitive coupling from 50 kV/m electric field in adjacent power lines
Mode: Signal conditioning circuit latch-up at 1.2 V overvoltage
Strategy: Faraday shield with 0.5 mm aluminum enclosure and TVS diodes clamping at 0.8 V
