Average temperature measurement with VITO temperature probes ___________________________________________________________________________ 2.2.1 Average temperature settings Before programming the temperature data, the sensitive length and the offset of the temperature probe must be known (refer to figures 2.1 and 2.2). Sensitive length: The sensitive length is retrieved from the position of the highest element. This figure is given in the Model selection code (positions 13, 14, 15 and 16, which are the last four figures) and is in the units of cm. In case the Model selection code cannot be read, the position of the highest element is also engraved on the coupling of the adjusting pipe of the VITO probe. The engraved figure is in the units of mm. For the combi probes (water & temperature probes) the sensitive length depends on the length of the water probe (given in position 2 of the Model selection code). Offset: The offset depends on the model of the temperature probe and is listed in table 2 – 2. When position 8 of the Model selection code is a ‘D’, the offset to the bottom of the probe is always 0.065 m (2” 9 / 16 ). For combi probes (water & temperature probes), and with the position 8 of the Models selection code a ‘C’, the offset depends on the length of the water probe (given in position 2 of the Model selection code). To the above described offset must be added the distance: tank zero - bottom of probe to obtain the offset figure needed in item MO. In case the Model selection code cannot be read, there are several ways to find out the correct model of probe. • Orange wire present in wire loom of VITO probe: position 8 of Model selection code is D • Orange wire absent in wire loom of VITO probe: position 8 of Model selection code is C • During (and after) commissioning, check by the temperature pointer items: VP=03.10 and VV • Length of water bottom probe can physically be measured VITO probe model sensitive length offset to bottom of probe ****764C ****764D ****767C ****767D *A**766C *A**766D *A**768C *A**768D *B**766C *B**766D *B**768C *B**768D *C**766C *C**766D *C**768C *C**768D Table 2 – 2 - 1 m ( - 3’ 3” 6 / 16 ) - 1 m ( - 3’ 3” 6 / 16 ) - 1 m ( - 3’ 3” 6 / 16 ) - 1 m ( - 3’ 3” 6 / 16 ) - 1 m ( - 3’ 3” 6 / 16 ) - 1 m ( - 3’ 3” 6 / 16 ) - 1 m ( - 3’ 3” 6 / 16 ) - 1 m ( - 3’ 3” 6 / 16 ) - 1.5 m ( - 4’ 11” 1 / 16 ) - 1.5 m ( - 4’ 11” 1 / 16 ) - 1.5 m ( - 4’ 11” 1 / 16 ) - 1.5 m ( - 4’ 11” 1 / 16 ) - 2.5 m ( - 8’ 2” 7 / 16 ) - 2.5 m ( - 8’ 2” 7 / 16 ) - 2.5 m ( - 8’ 2” 7 / 16 ) - 2.5 m ( - 8’ 2” 7 / 16 ) 1 m (3’ 3” 6 / 16 ) 0.065 m (2” 9 / 16 ) 1 m (3’ 3” 6 / 16 ) 0.065 m (2” 9 / 16 ) 1 m (3’ 3” 6 / 16 ) 0.065 m (2” 9 / 16 ) 1 m (3’ 3” 6 / 16 ) 0.065 m (2” 9 / 16 ) 1.5 m (4’ 11” 1 / 16 ) 0.065 m (2” 9 / 16 ) 1.5 m (4’ 11” 1 / 16 ) 0.065 m (2” 9 / 16 ) 2.5 m (8’ 2” 7 / 16 ) 0.065 m (2” 9 / 16 ) 2.5 m (8’ 2” 7 / 16 ) 0.065 m (2” 9 / 16 ) Note: In the model selection code given in table 2 – 2 an asterisk ‘*’ represents any character, the notation means: overall length (4 figures, positions 9-12, units: cm) and the notation means: position of highest element (4 figures, positions 13-16, units: cm).
