Surya Industrial Products is a premier RTD Sensor Manufacturers in Pune, Suppliers, and Dealers in Pune. An RTD Sensor is a sensitive and consistent temperature sensor device that is employed to gauge the temperature by equating the resistance of the sensor element with temperature. RTDs are also characterized by accuracy, permanence and reproducibility, which makes them perfect in industrial and laboratory applications where precision of temperature control, is essential.
What is an RTD Sensor?
RTD Sensor is an instrument that is used to measure temperature by monitoring how the electrical resistance of a metal changes with temperature. The metal resistance is increased in a foreseeable and reproducible way with an increase in temperature, which helps in the accurate measurement of temperature. The element of an RTD is typically platinum (Pt) because it is highly stable and is very accurate and linear over a broad temperature range.
Types of RTD Sensor
Being the top RTD Sensor Suppliers in Pune, we are providing the best quality of RTD Sensor such as:
By construction
Wire-wound RTDs: These are made by wrapping a fine platinum wire around a ceramic or glass core. They are characterized by their high accuracy and stability, particularly at high temperatures, and therefore, they are suited to those applications that need high accuracy over a broad range.
Thin-film RTDs: RTDs of this type are prepared by coating a ceramic substrate with a thin layer of platinum, which is then etched to form a pattern. They tend to be less expensive, respond more quickly, are smaller, and less prone to vibration and thermal shock than those made of wire-wound.
By material
Platinum RTDs: The most widespread type, commonly labeled as Pt100 or Pt1000, is the most precise, and its temperature resistance characteristic is constant and linear across a large temperature span.
Nickel RTDs: These are not very common and are characterized by being cheaper than the platinum RTDs. Their resistance also varies more as temperature changes, but these are restricted to a smaller temperature range.
Copper RTDs: This is also less common, and is only used in applications where their properties are needed (e.g., some motor windings). They can be confined to a range of relatively small temperatures.
By wire configuration
2-wire configuration: The simplest configuration is applied when the lead length is short enough that the resistance of the wires does not have a significant effect on the accuracy of measurements.
3-wire setup: This is used to improve precision over the 2-wire system by adding a third wire to counter lead wire resistance.
4-wire set up: The most precise design, in that both the current supplying and voltage drop across the RTD element are measured using separate pairs of wires to eliminate the lead wire resistance.

Surya Industrial Products is a best RTD Sensor Manufacturers in Pune, Suppliers, and Dealers in Pune. An RTD Sensor or Resistance Temperature Detector is a very reliable and accurate temperature measurement instrument that is commonly used in industries to measure and control temperature accurately. It has the advantage of being more stable, repeatable and linear, which makes it a vital component in modern process systems where precision is vital. RTD Sensors are useful in improving product quality, efficiency of the process and safety of operation by ensuring that the temperature readings remain constant in a large range.
The principle of RTD sensor is that, the higher the temperature, the more electrical resistance increases of a metal (typically platinum). The sensor then transforms this resistance change to a reasonable temperature.
The standard ones are 2 wires, 3 wires and 4 wire RTDs with varying degrees of accuracy and wiring resistance compensation.
The RTDs are more stable and have a more accurate range of temperatures in a smaller range but the thermocouples cover a wider range unlike the RTDs. RTDs are selected in the event of particular control of the processes.
