NOTE: The black outer jacket of the cable is Santoprene® rubber. This compound was chosen for its resistance to temperature extremes, moisture, and UV degradation. However, this jacket will support combustion in air. It is rated as slow burning when tested according to U.L. 94 H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.

The overall probe accuracy is a combination of the thermistor's interchangeability specification,
the precision of the bridge resistors, and the polynomial error. In a "worst case"
all errors add to an accuracy of ±0.4°C over the range of -24° to 48°C
and ±0.9°C over the range of -38°C to 53°C. The major error component is
the interchangeability specification of the thermistor, tabulated in Table 2-1. For the range
of 0° to 50°C the interchangeability error is predominantly offset and can be determined
with a single point calibration. Compensation can then be done with an offset entered in the
measurement instruction. The bridge resistors are 0.1% tolerance with a 10 ppm temperature
coefficient. Polynomial errors are tabulated in Table 2-2. |
