The AST47HP Series of pressure sensors addresses the growing need for pressure sensors with higher pressure ratings.
New from American Sensor Technologies (AST) is the AST47HP Series of pressure sensors, addressing the growing need for pressure sensors with higher pressure ratings.
Available in pressure ratings up to 4000bar, the AST47HP pressure sensors are ideal for operation in diesel fuel rails, high-pressure wells, hydraulics, injection moulding equipment, water jets, down hole instrumentation and more.
"With an increasing emphasis on vehicle efficiency, diesel fuel rail systems are being redesigned to run at higher pressures", states Karmjit Sidhu, AST's Vice President of Business Development.
"AST is able to meet the new requirements of engine manufacturers by supplying AST47HP pressure sensors with pressure ratings up to 4000bar".
The AST47HP is also popular among water jetting applications used in food processing, concrete and tile cutting, and metal fabrication.
AST47HP sensors incorporate a one-piece stainless steel sensing element, which is free of silicone oil, welds or O-rings.
The absence of these characteristics eliminates the chance of contamination from outside media, critical in food processing applications.
With AST's Krystal Bond technology, the sensing element offers a thick diaphragm that eliminates long-term drift, which can be common in high pressure and high cycle applications.
A stainless steel housing is welded to the sensing element for optimum protection of the sensor's electronics.
Units are rated for over 100 million pressure cycles and withstand 100V/m of EMI/RFI to protect against electrical noise.
To address different pressure requirements, the AST47HP pressure sensors are offered in a variety of high-pressure fittings.
Operating over a wide temperature range of -40 to +85C, the sensors offer a standard accuracy of better than +0.25% BFSL.
AST47HP pressure sensors are available with outputs of 10mV/V (50mV), 0-5V (three or four wire), 0-10V (three or four wire), 1-5V, 1-6V, 1-10V or 4-20mA (loop) to address different application requirements.
A wide variety of electrical connections are also available with cable, Hirshmann connectors and military connectors.
