Intrinsically safe pressure sensor

The PT4400 pressure sensor series is designed for intrinsically safe locations. The series utilises a media-isolated stainless steel diaphragm for use in pneumatics, water management, hydrogen storage, hydraulic systems, oil and gas, HVAC/R and industrial OEM equipment.

The PT4400 is rated for UL/cUL 913 (CSA 157) Class I, Division 1, Groups C and D when installed with an approved barrier, such as a Turck IM33 module. Constructed without welds or O-rings, these sensors allow for pressure ranges up to 10,000 psi and burst pressure ranges up to 20,000 psi.

PT4400 sensors are manufactured using MEMS (microelectromechanical systems) technology. With its one-piece sensing design, the PT4400 offers many advantages over other pressure sensing technologies, including a high life cycle, plus high overload and burst pressure cycles.
