Description
Precision Surface Temperature Sensing for Demanding Industrial Applications
The “Ji” Japsin Instrumentation Magnetic Surface Sensor RTD Pt-100, Simplex 3 Wire is a high-performance, industrial-grade temperature sensor specifically engineered for accurate surface temperature measurements. With a measurement range from -50°C to 450°C, this RTD sensor is ideal for a wide variety of applications requiring reliable contact-based thermal monitoring.
Designed for magnetic attachment to ferromagnetic surfaces, it enables non-invasive installation without requiring permanent mounting or system shutdowns. This makes it the preferred solution for steel piping, tanks, plates, reactors, and rotating or hot surfaces where welding or drilling is not feasible or desirable.
Its 5-meter stainless steel braided cable ensures enhanced durability in rugged industrial environments, while the Pt-100 element guarantees precise and repeatable readings.
Wide Operating Temperature Range (-50°C to +450°C)
Covers a broad spectrum of surface temperatures, making it suitable for both cryogenic and high-temperature environments.
Pt-100 RTD Sensor – Class A Accuracy
Incorporates a Class A platinum resistance temperature detector (RTD) that provides reliable accuracy and linearity. The platinum sensor follows the IEC 60751 standard curve for consistent output.
Magnetic Surface Mounting
Strong industrial magnet enables firm attachment to ferrous surfaces, eliminating the need for permanent installation. Ideal for quick setups, mobile monitoring, or maintenance tasks.
Simplex 3-Wire Configuration
Reduces lead wire resistance error while maintaining a simple wiring scheme. Compatible with most industrial temperature controllers, indicators, and PLCs.
5 Meter Stainless Steel Braided Cable
Designed for harsh environments where exposure to heat, abrasion, chemicals, or mechanical stress is a concern. The SS braided shield also protects against EMI/RFI interference.
Robust Construction
Built with durable materials and encased in a stainless steel probe body to withstand demanding usage in oil & gas, chemical, pharma, food, and energy industries.
Applications
The Magnetic Surface RTD is an extremely versatile sensor, making it an excellent choice for a range of industrial applications:
-
Pipeline Temperature Monitoring: Easily attachable to external pipe surfaces for real-time temperature measurement.
-
Boiler & Furnace Walls: Monitor heat zones without penetrating thermal insulation.
-
Motor, Bearing & Gearbox Surfaces: Detect overheating in critical machinery without intrusive sensors.
-
Process Vessels & Reactors: Measure temperature from outside metallic reaction chambers.
-
HVAC Systems: Quick diagnostics for duct or metallic surface temperature.
-
Research and Development Labs: Temporary sensor setups without permanent modifications.
Why Choose Japsin Instrumentation Magnetic Surface RTD Sensor?
Tool-Free Installation
No need to drill holes or perform mechanical modifications. Simply attach the magnetic probe to the desired location, connect the leads, and start monitoring immediately.
High Retention Magnet
The heavy-duty magnet ensures the probe remains securely in place, even in high-vibration or overhead installations.
Custom Lengths & Cable Options
While this model comes with a 5-meter SS braided cable, we offer custom lengths, terminations (fork lugs, connectors), and even armored cable options to suit your specific needs.
Exceptional Accuracy
Pt-100 Class A RTDs are among the most precise sensors available in the industry, ensuring your measurements are both accurate and stable over time.
Non-Invasive Monitoring
Unlike immersion or thermowell-type sensors, this surface probe can be used without breaching the process or system. This ensures safety, cleanliness, and no risk of contamination, which is critical in pharmaceuticals, food processing, and clean-room environments.
