American Sensor Technologies (AST), manufacturer of MEMS pressure sensors, transmitters and transducers, has introduced the AST4900 pressure sensor for measurement of liquid and gas pressure in high purity environments.

The sensor is based on MEMS technology and has received UL/cUL508 approval and a CE EN61326 certification. The use of Krystal Bond technology prevents the risk of contamination even under extreme conditions as welds, internal O-rings and oil-fills are avoided.

AST offers the AST4900 in 1/4" VCR Male and 1/4" NPT Male standard fittings. The sensing element is manufactured from 316L stainless steel or Inconel718 nickel alloy. It is capable of operating at temperatures ranging from as low as -40°C to 85°C. It can provide high-level current, frequency and voltage output signals. The sensor’s one-piece design helps maintain stability, high vibration and shock capability and ensures a high cyclical life.

The standard performance of the AST4900 sensor is rated to 0.25% BFSL. It also features a 5X burst pressure, 2X over range protection and can tolerate over 100 million pressure cycles. The sensor can be increased with pressure range from 0-25 PSI to 0-10,000 PSI.
