High LimitĮnter the maximum temperature that the temperature transmitter will measure.
In cases where these sensors are connect directly to the PLC. Please enter the value in the same temperature units as specified for all other input values. Thermocouple and RTD sensors are commonly used to measure temperature in industrial processes. You can enter negative (-) or positive (+) values. Repeat steps 4 and 5 and verify for a correct response. If not, adjust the device at zero (offset, 0) and span (gain, 100). If the measured output of the device is within limits, the test is complete. text.skipToContent text.skipToNavigation. Factors to consider when selecting the appropriate configuration.
RTD TEMPERATURE CONVERSION HOW TO
Low LimitĮnter the lowest temperature that the temperature transmitter will measure. Repeat the test, applying the 50 and 100 temperature signals. Learn how to wire an RTD with 2, 3 or 4 wires for temperature measurement in industrial applications. This is the applied temperature measured by the temperature transmitter that you wish to convert to a 4 to 20 milliamp current output reading. relatively linear, accurately converting measured resistance to temperature requires curve fitting. Linear mA out = 4 + (16 x ((Rdg – Low Limit) / (High Limit – Low Limit))) Parameters UnitĮnter the unit used for measuring temperature, e.g. raise the RTD temperature by 1 C, or 1 mW/C. This temperature transmitter output calculator uses the following formula to calculate the output over a 4-20mA range: A conversion scale graphic for each temperature and 4-20mA current output range combination entered is also displayed below the calculated values. This temperature transmitter 4 to 20 milliamp current output calculator provides a way to determine the output reading from the applied temperature and temperature transmitter range.
