†
The time constant is the time taken for the probe to reach 63% of the value of the temperature change. Multiply x 3 for the time taken to achieve 95% and by 5 for 99%.
Not suitable for Intrinsically Safe applications. Thermocouples:– Tolerances relate to BS EN60584–2 (1993), Class A. All dimensions are in mm.
