Hazardous Location Pressure Transmitter Catalog American Sensor Technologies, Inc. is a leading manufacturer of explosion proof transmitters and transducers for Class I and II / Zone 1 environments. Available in pressure ranges from 1 PSI to 20,000 PSI and various outputs, sensor types and pressure ports, the AST family of explosion-proof rated products will fit your performance and pricing requirements.

All AST explosion-proof products share a CSA 30 (UL1203/FM3615) Class I Division 1 Zone 1 Group IIC rating for Groups A, B, C, and D. Each product is also certified to ANSI/ISA 12.27.01-2007 Single Seal as required in the Canadian market. AST4600, AST46HA, AST46SW and AST46PT pressure transmitters are also certified for Exd locations under the ATEX directive. Other approvals such as ABS certification for marine and offshore equipment as well as Class II Division 1 approval for mining, are available on select products. Transmitters are available with CRN certification to standard B31.3 in certain configurations and materials.

All AST products with explosion-proof ratings feature a conduit fitting that is certified as factory sealed. Vented sensors adjust for barometric pressure through the side of the transmitter.

In addition to the hazardous location approvals, AST has some of the leading sensor technologies in its portfolio to produce reliable, repeatable pressure measurements. Pressures can be measured from 0-1 to 20,000 PSI with voltage or 4-20mA output signals. AST is a leading provider of sensors in oilfield applications requiring low current consumption for battery powered RTU / SCADA systems. AST's portfolio of materials allows customers multiple options including 17-4 PH, 316L, Alloy 718 and Alloy C276; this ensures long term operation and safety in the toughest hazardous environments.

Explosion Proof Differential Pressure Transducers

AST5300 differential pressure transducer AST5300 differential pressure transducer

American Sensor Technologies, Inc. (AST) has released the AST5300 explosion proof differential pressure transducer with explosion proof and non-incendive ratings. With a high line pressure and low differential pressure measurement. Free of oil-filled cavities, the AST5300 is an ideal fit for critical measurement of liquids and gases. The AST5300 is a reliable DP for gas flow measurement, CNG filters, valve safety and more.

AST now manufactures a differential pressure transducer with line pressures up to 5,000 PSI (350 bar). Designed to withstand high pressure hydraulic systems or low pressure pneumatics, the AST5400 differential pressure transducer is a simple, low cost solution for pressure feedback for filter monitoring, flow verification, and torque calculation. The AST5400 is also avaiable in explosion proof and non-incendive version. It can be designed with 316L, Hastelloy C276, Inconel 718, or 17-4 PH stainless steel. Ultra low pressures are available for vapor pressure and pneumatic applications as well.
