Temperature Sensor

High Temperature Sensor

• K Type Thermocouple, Range : 1200 Deg C

To make it simple, it is a means of assessment of temperature. It is a tool to measure the temperature and/ or the heating capacity of industrial equipments. Temperature remains one of the most consistent form of measurement. There are many methods for calculating or understanding it. The inbuilt part into the sensor, measures the temperature and it gets displayed on the face of the sensor device through an electric signal. Temperature influences most of the devices may be chemical,physical, mechanical or biological. A chemical manufacturing machine may have to be operated within a particular range of temperature, a mechanical type of machine requires a specific scale of temperature. Likewise we have temperature sensor applications in medical industries, food and beverage industries, consumer appliance industries. TS is used in measuring the particular temperature

There are 2 kinds, one is contact and the other is non contact sensor. With a contact sensor, the object or the person has to come in direct contact to be sensed, a thermometer is a body temperature sensor. In a non contact sensor radiation technology and the process of conveying is used to assess changes in the temperature. Digital temperature sensor consists of cable and a transmitter and is used for water and other industrial processes. The working of sensor depends upon the ignition across the semi conductor device. If the voltage rises the temperature also rises ,that way resistance shown by a semi conductor is directly proportional to the temperature change.

MERITS OF TS

• • These are low cost and extremely reliable even in repeated analysis.
• • These are self powered sensors.
• • We have a large variety of temperature sensors widely to be used in various industries.
• • The results displayed by the sensors are quite fast.
• • Highly durable devices.

DEMERITS OF TS

• • These are non linear instruments.
• • Give a low ouput voltage.
• • They are non sensitive.
• • Accuracy shown is not upto the mark.
• • Compulsory amplification required due to low voltage.
