Melissa Larson | October 9, 2014
American Sensor Technologies, Inc. (AST) has released explosion proof and non-incendive versions of its differential pressure transducer model AST5400. This addition compliments AST’s other products in the hazardous location market. AST added CSA certifications for Class I Division 1 and Class I Division 2 to the product series in order to satisfy market demands for differential pressure measurement. The product is capable of measuring line pressures up to 5,000 PSI (350 bar), providing an output signal of analog voltage or 4-20mA. Bi-directional calibration is available. Sensor material options include 316L stainless steel, Inconel 718, and Hastelloy C276.
Industries include well sites and compression equipment. The AST5400 product family will give engineers the opportunity for lower cost, high performance measurement for applications such as monitoring filters or dryers, ensuring flow, or calculating torque. In certain applications the AST5400 can be offered with an additional temperature output signal or an additional line pressure output signal, to reduce the total number of devices and saving money and installation time.
