Analogue  Series 387 - 3

Setting Ranges The values shown in this table are the UPPER RANGE LIMIT (URL); a 4:1 turndown facility enables full 4 to 20mA output to be obtained for a working span equal to 25% of URL. Unless specified, the instruments are despatched with LOWER RANGE VALUE (LRV) set to zero and UPPER RANGE VALUE (URV) set to URL. Medium Pressure Material Code “R” only. (Table 4) Accuracy ±0.15% Maximum working pressure Pmax 2 x URL. TABLE 5 Ranges shown are to gauge (i.e. atmospheric reference; absolute pressure is called up by amending the last character of the three character range code: Bar/mbar...
