Description

This CG-Stainless Steel sensor is a precision Resistance Temperature Detector (RTD) engineered for direct surface temperature monitoring. It utilizes a platinum PT100 sensing element, which exhibits a highly stable and linear resistance change with temperature, following the IEC 60751 standard (alpha=0.00385). The 3-wire configuration is critical for accurate remote sensing, as it allows the measurement circuit to compensate for the resistance of the connecting leads, ensuring the reading reflects only the temperature at the probe tip.

The pasted-type, flat-profile design maximizes surface contact area for rapid thermal response and minimal thermal lag. The stainless steel housing provides mechanical robustness and resistance to corrosion from acids, alkalis, and moisture, as indicated by its waterproof rating. This combination of precision, durability, and environmental protection makes it a reliable component for critical temperature feedback in controlled processes.

Key Features

High-Precision PT100 Element: Delivers stable, repeatable temperature readings with a nominal 100Ω resistance at 0°C.
3-Wire Compensation Design: Actively negates the influence of cable resistance, preserving signal integrity over the 0.5m connection.
Optimized Surface Coupling: Pasted-type probe geometry ensures low thermal resistance for accurate measurement of plates, casings, and heat sinks.
Industrial-Grade Durability: Constructed from corrosion-resistant stainless steel for long-term reliability in harsh conditions.
Environmental Sealing: Waterproof construction protects the internal element from humidity, condensation, and incidental fluid exposure.
Extended Temperature Range: Suitable for applications from ambient monitoring up to high-temperature processes at 800°C.

Applications

Surface temperature monitoring on industrial machinery housings, motor bodies, and heat exchangers.
Precise thermal profiling and control in laboratory ovens, furnaces, and environmental chambers.
Temperature feedback for PLCs and controllers in process heating, plastic molding, and food processing equipment.
Thermal management and overheating protection for power electronics heatsinks and transformer surfaces.
Condition monitoring in humid or wash-down environments where waterproof integrity is required.

Frequently Asked Questions

What is the advantage of a 3-wire configuration over 2-wire for this PT100 sensor?

The 3-wire design enables lead-wire resistance compensation. Two wires carry the measurement current, while the third measures the voltage drop directly at the sensor, subtracting the resistance contributed by the 0.5m cable. This significantly improves accuracy, especially over distance, compared to a basic 2-wire connection where cable resistance adds directly to the reading.

How do I mount this pasted-type PT100 sensor for accurate measurement?

For optimal thermal coupling, ensure the flat, pasted surface of the stainless steel probe is in full, clean contact with the target surface. Use a high-thermal-conductivity paste or adhesive recommended for high temperatures (if needed) to minimize air gaps. Secure it firmly with a clamp or high-temperature tape to maintain consistent pressure and contact across the operating range up to 800°C.

Can this waterproof sensor be used in submerged or high-pressure liquid applications?

While designated as waterproof, this typically indicates protection against humidity, splashing, and condensation. It is not designed for continuous submersion or high-pressure wash-down unless specifically rated for IP68 or similar. For submerged applications, verify the exact IP rating or consider a hermetically sealed, immersion-style probe.

What type of readout or controller do I need for this 3-wire PT100 sensor?

You require a temperature controller, PLC analog input module, or data acquisition system with dedicated 3-wire RTD input capability. The device must be configured for a PT100 sensor with a 3850 ppm/°C (0.00385 alpha) curve. Standard thermocouple inputs will not work correctly, as RTDs measure resistance, not voltage.
