PT-100 Temperature Sensor

Manufacturer of Pt-100 Temperature Sensor

We manufacture a variety of temperature sensors of PT-100 in Ahmedabad. The PT-100 is a form of platinum resistance thermometer consisting of platinum often referred to as PRT or Platinum Resistance Thermometer.

The resistance of PT-100 sensor in 0 C is 100 ohms, where PT is the platinum (Pt) and 100 is the sensors which are 0 C ready and the resistance is 100 ohms.

The PT-100 sensors are stable over the long term (greater than six months) with high accuracy (less than 0.2 ohm/o C per 1 C). They are available in various sizes in order to serve the needs of different clients and they are applied in many different uses.

Our PT-100 sensors are of good quality, and they are also very competitively priced hence are a favorite among our clients. We provide accuracy requirements and other packages depending on most of the applications and customer needs. Moreover, our products are sold at the most favorable rates.

We are an old firm in manufacturing, supplying and exporting Pt-100 Temperature Sensor that is a common type of platinum resistance thermometer.

Pt sensor is comprised of Platinum (Pt). 100 means that at 0 C sensor has a resistance of 100 ohms (Ω). One form of a temperature sensor is a resistance thermometer. Our P-100 Temperature is a strong industrial probe and it may be utilized in numerous applications.

The sensor has an in-head temperature transmitter that has a 4-20mA industry standard output and is programmable. This can easily be integrated into the existing process control equipment.

This sensor is applicable in the temperature measurement of liquids and gases within a broad range of temperatures -75 +250 O C. Our sensor is simple to install because it subtracts pipe work or tanks and vessels with the help of an appropriate mounting, e.g., compression fitting or thermo pocket.

The working principle of the PT100 sensor is used to measure temperature that falls into a group called Resistance Temperature Detectors or RTDs. The key word is “Resistance” because a Pt100 measures temperature by using a resistance change to denote the temperature value.

For a Pt100, the resistance at 0°C is 100Ω and at 100°C, it is 138.5Ω. Therefore, the resistance change for each degree Celsius change is 0.385Ω. Before understanding how the sensor works, it is worth looking at some of the terminology used as this is extremely useful to know when identifying a sensor.

The sensor type, Pt100, indicates two important pieces of information about the sensor. The first part, Pt, is the chemical symbol for Platinum and this shows that the sensor is Platinum-based.

The second part, 100, relates to the resistance of the device at 0°C. In this case 100Ω. There are several variations on this theme. Other materials can be used such as Nickel (Ni) and Copper (Cu) and different resistance values such as 50Ω, 500Ω and 1000Ω.

Features PT-100 Temperature Sensor

PT100 Working Principle is also called RTD PT100 working principle although platinum is a precious metal and as such, it is extremely costly, it provides the highest linearity and stability of any other substance.

It also enjoys the advantage of being highly resistant to corrosion and chemical attack as well as being highly stable at high temperatures. It is also used in high-temperature thermocouples as well as in Platinum Resistance Thermometers.

The mass of the Platinum to be used in the production of the sensing elements is so small such that the cost is even low and forms a small percentage of the overall cost of the end product temperature probe.
