Inertial Aerosystems is introducing a new affordable precision digital pressure transducer, with a hermetically sealed stainless steel construction. Designated the PPTR type, it is designed for use in harsh environments, and is especially suitable for use as a depth sensor.
This smart sensor combines proven silicon sensor technology with microprocessor-based signal conditioning, delivering repeatable, long-term accuracy of 0.1 per cent of span max (better accuracy on request) over the operating temperature range of -40 to +85 degrees C. Absolute or gauge configurations are available.
The PPTR can measure pressure to depths of up to 2000 meters (3000 psi). Simple system design ensures no additional signal compensation is needed, and efficient data acquisition can connect up to 89 units on a multidrop bus if using the optional RS-485 capability (RS232 standard). This versatile product can be installed with both existing and new systems. An optional hastelloy diaphragm is available to enable most media to be handled, such as harsh gases or liquids. An analogue 0-5V DC output is included.
High-quality and rugged, this unit has many programmable software features that support a wide range of applications including engine test stands, flight testing, water depth, unmanned underwater vehicles, instrumentation and analytical equipment, process and control, research and development - to name but a few.
