Sensor

RTD (Pt. 100) is available in 2 wire or 3 wire connection. Generally 3 wire is used for length compensation. Compensation is achieved for lead resistance and change of temperature in load resistance. This is the most commonly used configuration. RTD operates on the principle of change in electrical resistance in pt wire as a function of temperature. RTD is used for temperature range -200'C to 600?C. Thermocouple probe is a temperature measurement sensor that consists of two dissimilar metals joined together at one end (Junction) that produces a small thermometric voltage when the junction is heated. The change in thermoelectric voltage is interpreted by the thermocouple as a change in temp. The most common types are "J" (Iron-Constantan) up to 700'C & "K" (Chrome) - Alumel) up to 1200?C. These sensors are suitable for ovens, deep freezers, boilers, incubators etc. General Purpose Sensors are not suitable for liquid immersion application. For liquid immersion use Industrial Assembly Sensors.
