Temperature measurement B57703M Probe assemblies M703 Cautions and warnings General See "Important notes" on page 2. Storage Store thermistors only in original packaging. Do not open the package prior to processing. Storage conditions in original packaging: storage temperature 25 °C ... +45 °C, relative humidity ≤75% annual mean, <95% maximum 30 days per annum, dew precipitation is inadmissible. Do not store thermistors where they are exposed to heat or direct sunlight.
Temperature measurement B57703M Probe assemblies M703 Mounting Ensure that no thermo-mechanical stress occurs due to production processes (curing or overmolding processes) when thermistors are sealed, potted or overmolded or during their subsequent operation. The maximum temperature of the thermistor must not be exceeded. Ensure that the materials used (sealing/potting compound and plastic material) are chemically neutral.
