The SIKA VH500 paddle flow switch is modelled for applications such as cooling water monitoring, leak monitoring, and lubrication control. The SIKA VH 500 is placed with its paddle in flowing medium, which triggers the paddle. The resulting dynamic pressure causes the paddle to travel, which causes the actuation of integrated micro switches. SIKA flow switches monitor the flow of low-viscosity media in pipes. They offer a reliable solution for ensuring the minimum flow rate and thereby protecting high-quality systems and installations from damages. These flow switches work based on the well- established mechanical operating principles. Thanks to the different paddle lengths, the switch points of the paddle flow switches can be configured for a wide switching range.

The WIKA PG23LT high-quality pressure gauge has been designed specifically for extremely low ambient temperatures down to -70 °C (-94 °F). The stainless steel Bourdon tube pressure gauge finds applications in particularly cold regions such as Russia, Canada, Scandinavia or China. The WIKA model PG23LT is used primarily in the oil and gas industries and in the petrochemical industry. The typical measuring points are located on pipelines or in pumping stations for oil and gas transportation. As a result of the special low-temperature design of the instrument, the use of special seals and the case filling, the WIKA model PG23LT is suitable for outdoor applications down to an ambient temperature of -70 °C (-94 °F). The same instrument design fulfils the requirements for both IP 66 and IP 67 ingress protection for pressure ranges greater than 0 ¦ 16 bar. Tested and qualified in WIKA's own laboratory, the suitability of the instrument for ambient temperatures down to -70 °C (-94 °F) is confirmed as standard with each order by a 2.2 test report.
