PT100 with transmitter 4..20mA EASY-UP
Diameter 6mm with DIN head
Temperature measurement by resistance thermometers relies on a property common to all conductors and semiconductors, which is the variation in their electrical resistance in relation to temperature change. The PT100 sensor has an ohmic value of 100 at a temperature of 0°C and its variation coefficient is 0.00385 Ohm per degree centigrade.
The technology adapts to meet modern requirements and is designed to provide more precise measurements by using fine sheets of platinum on a ceramic substratum (thin film resistors).
The converter in the head of the probe converts the signal to 4...20mA in order to transmit the temperature value to the process instruments with a pre-selected scale.
The PT100 Easy-up probes are assigned a numeric code that once inserted allows the Pixsys controllers to automatically set the main operating parameters.
