Curtiss-Wright’s Industrial division has today announced the launch of a new range of robust pressure sensors, which have been designed for numerous industrial pressure sensing applications across sectors including: factory automation, process control, automotive and specialty vehicles, hydraulics, pneumatics and environmental systems.

The wide range of models and configurations offer an extensive choice of cost-effective solutions from low-cost, high-volume OEM production to high-performance Research & Development.

Featuring thin-film and diffused-silicon sensing elements, the piezo-resistive sensing technology is inherently accurate, small and robust with stainless-steel body construction.

Stainless-Steel Technology: Thin-film polysilicon resistors are applied to a stainless-steel diaphragm that deflects under pressure from the measured media, providing a varying voltage that can be converted into other electrical outputs. Benefits include long-term stability exceeding 0.1% per annum and excellent compatibility with a wide range of gas and fluid media, operating at ranges up to 0 to 4000 bar.

Silicon Technology: The sensing element features a silicon diaphragm into which pressure-dependent resistors have been diffused. The technology is a cost-effective solution for high-volume manufacturing, and especially suited to large-batch production. This technology is more suited to non-aggressive gas and fluid media, operating at ranges from 0.1 to 40 bar.

Both technologies are integrated into stainless-steel housings with a choice of pressure port and electrical connection options. This enables it to be readily adapted into numerous different sensor configurations to suit specific customer needs.

Pressure modes include absolute (relative to a vacuum), gauge (relative to ambient atmospheric), differential and sealed reference options, with measurement accuracies nominally 0.5% at room temperature, with an option to 0.1% in the high precision range. Special intrinsically safe ATEX/EX approved versions are also available for use in Zone 0 and 1 hazardous areas.

This extensive pressure sensor range complements the existing range of Curtiss-Wright position sensors from the Penny & Giles brand family, and offers existing and new customers a wider choice of sensing solutions from one supplier.

Within the business are four market leading brands — Penny & Giles Controls, PG Drives Technology, William Controls, and Arens Controls.

Penny & Giles Controls
Delivers rugged component level solutions using the latest non-contact sensing technologies, and specialises in rotary, linear and tilt position sensors; joysticks; solenoid actuators and associated electronic signal conditioning. The business was first established in 1956 and pioneered aerospace sensing and data recording technologies with a reputation for quality, performance and reliability. The aerospace business continues today within other Curtiss-Wright business units. The company joined Curtiss-Wright in 2002.

PG Drives Technology
Delivers rugged subsystem solutions including programmable controllers and drives used in a wide variety of advanced electric-powered vehicles such as forklifts, pallet loaders, mobility scooters and wheelchairs, serving the industrial and medical markets. These products deliver precise variable power from batteries to electric drive motors, and are fully programmable to suit various motor profiles, voltages and power levels. The business was first established in 1976 and was originally part of the Penny & Giles group of companies. The company joined Curtiss-Wright in 2012.

Williams Controls
Delivers rugged component level solutions and is a leading designer and manufacturer of highly-engineered electronic sensors and electronic throttle controls for off-road equipment, heavy trucks, and military vehicles. The business was first established in 1937 and pioneered the development of the first electronic throttle control for large diesel engines, quickly becoming the world leader in the design and manufacture of electronic throttle controls for trucks and buses. The company joined Curtiss-Wright in 2012.

Arens Controls
Delivers rugged component level and subsystem solutions and is a leading designer and manufacturer of highly engineered electronic shift controls for automatic transmissions used on heavy trucks and buses. The company also designs and manufactures power management and traction systems for the emerging Hybrid Electronic Vehicle (HEV) market. The business was first established in 1939 and pioneered the development of “by-wire” vehicle control technology, and more recently power electronic drivetrain components and systems for the HEV market. The company joined Curtiss-Wright in 2013.

Curtiss-Wright Industrial Group has manufacturing sites in the US, Europe, India and China. Total customer service and support is assured via a global sales network with CWIG offices in the US, UK, Germany, India, Taiwan and China, as well as a network of distributors and agents covering other regions.
