Pressure Transmitter with Display
American Sensor Technologies, Inc. (AST) has released the AST46DS Explosion-Proof Pressure Transducer with Display with pressures from 1 to 20,000 PSI available. The AST46DS is a price-competitive transducer with zero function capability, voltage or 4-20mA output signals, and all 316L stainless steel sensor materials.The voltage output signal is ideal for oil and gas well site applications. With many SCADA / RTU sites powered by solar panels in remote locations, a pressure transducer with low current consumption is ideal to extend life. The AST46DS can operate as low a 8VDC and has current consumption with voltage outputs as low as 2mA.The AST46DS is also an excellent solution for offshore platforms.
The transducer housing has a special, layered paint suitable for NEMA 4X environments and salt spray conditions. Using 316L SS, the transducer is compliant to NACE MR0175/ISO 15156.The AST46DS pressure transducer comes standard with a 316L stainless steel 1/2" NPT Male process connection. Featuring Krystal Bond™ Technology, the process connection has a large opening to minimize clogging and the thickest diaphragm in the industry. Additional material options include Alloy 718 and C276. Outputs of 1-5V or 4-20mA are standard. Users can cycle through the display modes of the output signal and six different pressure unit types (PSI, Bar, Mpa, Kpa, inches of water column, and kg/cm²). Additionally, users can re-zero the zero pressure reading through the push button display.
The AST46DS is packaged with various hazardous location approvals including Class I, II and III Groups A, B, C, D, E, F and G areas for explosion-proof and non-incendive applications. Each pressure transducer also features ANSI/ISA 12.27.01 single seal approval. For applications requiring CRN B31.3 approval, contact AST.
