PG23LT Bourdon Tube Pressure Gauge

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 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 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.
