The instrument is mounted by BSP 1 ½ "or NPT process connection, or a flange. There are two models, one with a 4-mm cable. diameter (maximum probe length: 10m) and one with a cable of 8 mm. diameter (maximum length of the tube: 20 m). During filling and emptying the product has a load that is limited to a maximum value should not exceed: 10 ki '\\ l for 4 mm cable. and 40 kN for the 8 mm. and of course, mounting on top of the silo must be capable of withstanding these forces. To prevent the probe tip to a hose or a link to Excel, the counterweight end of the string should be facing toward the silo and the diameter of the tubing should be at least as high as wide (see fig . 13 (A)). To prevent false changes in impedance, the cable must hang freely at least 30 cm. wall or any other object in the silo. You can mount this system partially filled silo, after making a map of partial adjustment, the system is ready for measurement. During unloading, silo cable fully stretched (see Fig 13 (B)). If the product is expected to move the cable to less than 30 cm. silo wall, the tip of the probe can be anchored to the bottom (or tapered) of the silo. If, moreover, is tied with no insulation will act as a ground.
