AST4520 submersible pressure sensor

The AST4520 is a media-isolated, submersible pressure sensor with an all-stainless-steel construction that is approved to Underwriters Laboratories / Canadian Underwriters Laboratory (UL/cUL) 913 Class 1, Division 1 IS, Groups C and D, when used with an approved barrier. It is a cost-effective solution for monitoring the level of viscous media in turbulent tanks. Its flush-diaphram steel-cage design allows for proper media flow while keeping the sensor at the bottom of the tank or well. It is suitable for many submersible and level measurement applications, including wastewater and stormwater systems, industrial lift stations, and holding tanks. Units operate over a temperature range of –40º to 85ºC and have pressure ranges of 0–5 psig to 0–15 psig. They come standard with ±0.25% best-fit-straight-line (BFSL) accuracy, electromagnetic interference and radio frequency interference (EMI/RFI) protection of 100 V/m, and a 4–20-mA output.
