Pressure/Temperature Sensors One Sensor, Two Outputs: Messuring pressure and Temperature Simultaneously

| Editor: Dominik Stephan

It's old the 'two birds, one stone' idea: New sensors measure both pressure and temperature from a single process point. This dual output configuration reduces process penetration points and leaks that are important considerations in critical systems such as hydrogen, oxygen, heavy oil processing, hydraulics, analyzers, offshore, pipelines and ammonia systems.

American Sensor Technologies (AST) introduces two new sensor units that simultaneously measure pressure and temperature: The Model AST20PT Stainless Steel Media Isolated Pressure/Temperature Sensor and Model AST46PT Explosionproof Pressure/Temperature Transmitter that can help to save costs - as both units provide two functions in a single device - but also to cut energy expenses.

Wide Application Range for Combined Pressure/Temperature Sensors

With their microprocessor-controlled design, along with AST’s proven one-piece body construction, both units provide high accuracy pressure and temperature measurements of +/-0.1% and 1.0% BFSL, respectively. The bdevices are available with various operating temperature ranges from -40° to 125°C ( -40° to 250°F). While the Model AST46PT can be acquired in pressure ranges up to up to 20,000 PSI (1,400 Bar), the Model AST20PT is available in pressure ranges up to 45,000 PSI (3,100 Bar).

Measuring Pressure and Temperature in Hazardous Areas

Both units can be constructed in a wide range of wetted materials, including high-quality stainless steels and superalloys: 17-4PH SS, 316L SS, Inconel 718, Waspalloy, and Hastelloy C-276. The Model AST46PT is also CSA-approved for use in hazardous areas including Class 1 Div 1 explosion–proof groups A, B, C and D, and for mining applications, Class 2 Div 1 Groups E, F and G.
