Product Introduction
Product Overview & Core Application Positioning
The Screw Type Stainless Steel Thermocouple Temperature Sensor is a high‑precision, rugged industrial temperature sensing component professionally developed for industrial automation, heating equipment, packaging machinery, food processing, environmental chambers, and mechanical equipment. Available in both PT100 and CU50 sensing elements, this sensor uses a screw‑mount stainless steel probe structure, providing stable, reliable, and fast temperature detection in harsh environments including high temperature, humidity, vibration, and corrosion.
As a core supporting component for temperature controllers and solid‑state relays, this sensor is widely used for real‑time temperature collection and feedback. Suosite Electrical, with more than 10 years of experience in industrial sensors and temperature control instruments, has designed this screw‑mount sensor for durability, high accuracy, and easy installation. Its compact structure, metal screw locking, and waterproof, rust‑proof properties make it suitable for long‑term use in industrial sites. Whether for new equipment manufacturing, equipment maintenance, or system upgrades, this sensor provides stable and accurate temperature signals to ensure precise control and safe operation.
Key Product Features
This screw‑mount stainless steel temperature sensor has a full set of industrial‑grade features suitable for long‑term use in harsh environments.
First, it adopts a solid stainless steel probe and screw structure, with excellent waterproof, dustproof, rustproof, and corrosion‑resistant performance, ensuring stable operation in humid, oily, or mildly corrosive environments.
Second, it supports dual high‑precision sensing options: industrial PT100 platinum resistor and CU50 copper resistor, allowing users to select based on accuracy, temperature range, and system compatibility.
Third, the screw locking installation method enables firm fixation, close contact with the measured surface, fast thermal response, and reduced measurement error.
Fourth, it features highly flexible and high‑temperature resistant wire with good tensile strength, aging resistance, and interference resistance, ensuring stable signal transmission.
Fifth, it has a compact and lightweight structure, easy to install in narrow spaces such as electrical cabinets, pipes, heating plates, and molds.
Sixth, it offers wide measuring range and high stability, with small drift, long service life, and low maintenance requirements.
Seventh, it supports customization of probe length, wire length, connector type, and thread specification, fully adapting to different equipment structures and installation requirements.
Finally, it has strong compatibility, matching almost all digital temperature controllers, PLC modules, and data acquisition systems on the market.
Technical Advantages & Stability Performance
Backed by Suosite Electrical’s professional R&D and strict quality control, this screw‑mount temperature sensor provides outstanding technical advantages and long‑term reliability.
The core uses high‑precision PT100/CU50 sensing chips with good linearity, low drift, and high accuracy, ensuring stable output even under long‑term continuous operation.
The fully sealed stainless steel structure provides excellent physical protection, effectively resisting vibration, extrusion, moisture, and oil stains, widely used in harsh industrial environments.
Fast thermal response design reduces delay and improves control system real‑time performance, helping temperature controllers achieve faster and more stable regulation.
The internal uses high‑temperature insulation and filling materials, with good thermal conductivity and insulation, ensuring accurate sensing and safe use.
Each sensor undergoes strict factory calibration, temperature cycling test, and air‑tightness test, with excellent consistency and stability.
Compared with conventional plastic‑shell sensors, this stainless steel screw model has higher strength, longer life, and wider application scenarios, greatly reducing replacement frequency and failure rate.
With strong anti‑interference ability, it can work stably near inverters, motors, and high‑power equipment without signal distortion.
