| Signalling F3. DK-1B Capacitive Level Indicator |
||||||
| These units are used for level control in silos and hoppers. To splice the probe for use in places or machines in which the material is subjected to high temperatures, use A.T. silicon cable wrapped in GM-1000 isolation casing capable of withstanding temperatures of up to 450º; it must have a dry breakdown strength of 1,000 V. When used in hoppers and silos, the probe is suspended directly from the indicator head by Ø10 mm stainless steel rod or cable. The standard probe consists of a Ø 20 arm, the upper part of which is isolated with 400 mm long polypropylene. The splicing cable for the probe may be positioned near control circuits but should always be kept away from power systems. The device is designed to run on alternating voltage of 220 V. 50-60 Hz. Probing in hoppers where the temperature exceeds 65º C must be done on “HEAT RESISTANT” mode. Probing materials with a high dielectric coefficient must be done on “MIRROR SHINE” mode using stainless steel plates. |
