What is an RTD? How It Works & Why It’s Reliable
An RTD, or Resistance Temperature Detector, is a temperature sensor that works by measuring the change in electrical resistance of a metal—typically platinum, nickel, or copper—as temperature varies. This resistance change offers a linear and highly accurate reading, making RTDs one of the most reliable solutions in industrial environments.
The advantages of RTD sensors include excellent precision, long-term stability, and consistent repeatability across a wide temperature range.
At AIMS Controls, we engineer RTDs tailored for industrial reliability—serving manufacturing hubs across Gujarat and beyond.
Types of RTD Sensors You Should Know
When selecting the right temperature sensor for your process, understanding the types of RTD sensors is essential. RTDs come in multiple configurations—each suited for specific levels of accuracy and application complexity.
- 2-wire RTD: Simple and cost-effective, but best suited for short-distance, low-precision applications due to lead wire resistance.
- 3-wire RTD: The most commonly used type in industrial setups, offering a good balance of accuracy and cost by compensating for lead resistance.
- 4-wire RTD: Provides the highest accuracy by fully eliminating lead wire resistance. Ideal for lab and precision instrumentation environments.
- Thin-film RTDs: Compact and faster in response, they’re suited for surface temperature monitoring and tight installations.
- Wire-wound RTDs: Known for high accuracy and wider RTD temperature range, these are used in critical industrial applications like chemical processing and power generation.
Each of these RTD sensor types offers specific benefits depending on your system’s needs.

Key Advantages of Using RTD Sensors
Resistance Temperature Detectors (RTDs) are widely valued in industrial environments for their precision, reliability, and robust performance over time. Here’s a deeper look into the key advantages of RTD sensors—especially those engineered by AIMS Controls in Gujarat, India:
- Superior Accuracy:
RTDs are known for their high measurement precision, typically within ±0.1°C. This makes them ideal for industries like pharmaceuticals, food processing, and chemical manufacturing, where even minor temperature deviations can affect quality or compliance.
- Long-Term Stability:
Unlike thermocouples, RTDs exhibit very low drift over time. This means you won’t need frequent recalibration, which is essential for continuous production environments such as power plants or petrochemical facilities.
- Low Signal Degradation (Drift):
Thanks to their design, especially in 3-wire and 4-wire RTDs, signal loss due to lead wire resistance is significantly reduced. This ensures that data remains consistent even with extended wiring or in high-noise electrical environments.
- Broad Compatibility:
RTDs are highly compatible with a wide range of transmitters and PLCs (Programmable Logic Controllers). Whether you’re upgrading a legacy system or integrating into a new automation line, AIMS Controls’ RTDs ensure smooth compatibility without complex interfacing.
- Durable Construction:
RTDs supplied by AIMS Controls are built using high-grade materials such as platinum, stainless steel sheaths, and advanced insulation techniques. This construction ensures durability in extreme conditions—be it high pressure, corrosive media, or frequent thermal cycling. - Custom Engineering Support:
AIMS Controls offers custom configurations tailored to your process needs—whether you require specific sheath lengths, unique sensor outputs, or RTDs integrated with thermowells. Our in-house engineering team ensures that your sensor performs reliably, right from design to deployment.
- Energy Efficiency & Cost-Effectiveness:
Due to their stability and minimal maintenance requirements, RTDs help reduce downtime and operating costs in the long run, making them an economically wise choice for process-critical industries.
