1. How long does it take to get a reading?
Multiply the specified time constant by five.
2. How do I determine the accuracy of a system (probe and meter)?
Add together the stated accuracy of each.
3. When there are two accuracy statements, which one is correct?
The general rule is to use the accuracy statement that gives the greatest error in the measuring situation.
4. What are the benefits of grounded, ungrounded, and exposed probe junctions?
GROUNDED JUNCTIONS are welded to the tip of the sheath with wires completely sealed from contaminants. They offer good response times and are ideal for measuring the temperature of static or flowing corrosive gases and liquids.
5. What colors are the lead wires of each thermocouple type?
A: In the U.S.A:
6. How far can I transmit my temperature signal?
In an electrically clean environment, thermocouple, RTD, and thermistor signals can be transmitted up to 200 feet (61 meters) without amplification. To transmit a thermocouple signal over greater distances, use thermocouple extension wire; for RTD and thermistor signals, use shielded copper extension wire.
7. How do I measure samples without contacting them?
Use an infrared thermometer.
