Description
Model 101.00, 101.12 are mechanical pressure gauges with a plastic capallary. These instruments are based on the proven Bourdon tube measuring system. The plastic case is available in nominal sizes of 27 mm and 40 mm.
Features of the plastic capilary
Due to the length and flexibility of the capilary, the mounting position of the indictor can be independent of the measuring point. Through the use of a specific plastic, the long-termm resistance of the capillary is also maintened at high temperatures. An advantage of plastic capillaries, as against copper capillaries, is that these do not need to be bent or coiled. Thus, the plastic capillary makes installation much easier and eliminates the risk of any fatigue fracture.
Application area in heating technology
These instruments are particulary suitable for application in the heating industry. The suitability of the instrument was confirmed in long-term test under chracteristic application conditions.
Individual Customer Variants
Based o many years of experience in manufacturing and development, WIKA is also happy to offer customers-specific solutions. The G 1/4 B standard process connection can, on request, also be completed with a plastic sealing ring at the thread. This eliminates the time-consuming-specific process connection design, WIKA also offers the development of plastics plug connections to meet the requirement.
