A temperature sensor plays a significant role in various applications. For example, the maintenance of a specific temperature is crucial for equipment is useful for the fabrication of heat liquids, medical drugs, or cleaning other equipment.
For applications like these, the accuracy and responsiveness of the detection circuit can be quite critical for the purpose of quality control. Below are five tips for selecting and using a temperature sensor probe:
- Temperature range:
This is the first and foremost consideration while selecting the temperature sensor. In order to operate in environments over 1000 degree C, a thermocouple is the only option. This is when only a few applications involve extreme temperatures.
For most of the medical, consumer, industrial, and general embedded systems, the usual operating temperature range is a lot narrower. With semiconductor-based components, the range gets even more limited.
Brass Temperature Sensor can get drifted over time, which depends on the construction, materials, and the packaging used. Stability is essential in applications which need to be operational for multiple years.
The effects of the stability can be easily mitigated when the system can be calibrated from time to time, although it comes with the trade-off of the introduction of maintenance cost and complexity. Ideally, the stability is enough for it to extend through the entire expected life of the operation.
A few resistance elements are a lot susceptible to the vibration that may give way to problems that include noisy signals, variations or open circuits in temperature readings. The thermocouples tend to perform a lot better in applications where the sensors are exposed to extremely high vibration as the size of wires is used in them. Brass Temperature Sensors suppliers in Mumbai offers a temperature sensor probe at a cost-effective price.
Although the initial cost is typically less compared to platinum RTD, thermocouples require frequent calibration and maintenance because of the wire corrosion, and thanks to the moderate environments where they operate RTDs have a longer useful life.
Thermocouples further need matching extension wires for the purpose of sensor configuration that can drive up the material costs. This is especially true for the long wire runs. The cost of a temperature detection circuit usually rises within increased accuracy for a specific sensor type.
Without a proper detection circuit, the reliability and quality of temperature control along with the compensation of functionality degrades. There are various factors which affect the temperature accuracy detection circuit that includes responsiveness and resolution.
Accuracy is a concern for applications that need precise temperature control. However, the accuracy has a substantial in multiple applications where the temperature is a reliability concern.
Once the temperature sensor is selected, it needs to be integrated into the control system that is based on a PLC or DCS. While one method is to connect the RTD directly, the other method is temperature signal conditioners, becoming largely popular because of the benefits they provide.
