American Sensor Technologies Inc. (AST) has introduced the AST46DS explosion-proof pressure transducer with display supporting pressures from 1-20,000PSI. According to the company, the device 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 geared 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 aimed to extend life. The AST46DS can operate as low a 8VDC and has current consumption with voltage outputs as low as 2mA, added the company.

The AST46DS is also intended 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 pressure transducer comes standard with a 316L stainless steel 1/2in NPT male process connection. Featuring Krystal Bond technology, the process connection has a large opening to minimise 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.

Pricing starts at $825 each with quantity discounts for as few as 10 pieces.
