The proper sensor type is also a very important factor in obtaining precise measurements. The sensor must have the
correct temperature range to meet the process requirements. In special processes, the sensor might have additional
requirements such as leak-proof, anti-vibration, antiseptic, etc.
Standard sensor limits of error are ±4°F (±2°C) or 0.75% of sensed temperature (half that for special) plus drift caused
by improper protection or an over-temperature occurrence. This error is far greater than controller error and cannot be
corrected on the sensor except by proper selection and replacement.
