AccuStar® Electronic Clinometer from Sherborne Sensors

Sherborne Sensors has announced the AccuStar® electronic clinometer, designed to provide precision angular measurements within applications where a high degree of accuracy is required.

The unique design of the AccuStar® incorporates a capacitance-based sensor without moving parts. When rotated about its sensitive axis, this sensor provides a fundamentally linear variation in capacitance, which is electronically converted into high-precision angular data. Available in choice of analog, ratiometric, digital or serial models, the AccuStar® electric clinometer offers a ±60° measurement range, outputting a signal that corresponds to the direction and magnitude of angular displacement. The highly compact AccuStar® measures just two inches (50 mm) in diameter and weighs just two ounces (60 grams) for easy installation, with units designed to reliably operate in temperatures of -30 to +65°C. The sensor and its associated low-power CMOS electronics are encased in a rugged plastic housing.

With its durable, high-performance design, the AccuStar® is ideal for a multitude of applications, including off-highway vehicles, wheel alignment, construction equipment, antenna positioning and robotics applications, as well as other portable or mobile applications where space constraints or environmental concerns preclude the use of other types of precision angle measurement devices.

Ultra-Thin Absolute Pressure Sensor

San Juan Capistrano, CA – Meggitt Sensing Systems announces the debut of Endevco® model 8515C, a miniature, high-sensitivity piezoresistive pressure transducer, designed for surface air flow and other aerodynamic measurements requiring high output in a small, lightweight package.

The ultra-low profile design of Endevco® model 8515C has an overall thickness of 0.030 inch (0.76mm) and diameter of 0.250 inch (6.3mm). Units are available in ranges of 15 and 50 psia, with 200 mV full scale output, and frequency responses of 180 kHz and 320 kHz, respectively. The transducers offer stable performance over an temperature operating range of -65 to +250°F (-54 to +121°C), with combined non-linearity, non-repeatability and pressure hysteresis error of less than 0.50% FSO. In addition, model 8515C is designed to survive 10,000 g shock and 10,000 g acceleration, with minimum 5X burst pressure, making it the best performing pressure transducer of its kind in the industry.

Model 8515C is supplied with an integral cable, and is typically surface mounted onto curved surfaces, for minimal effect on laminar air or hot gas flow. A flush mounted fit may also be achieved by recessing both transducer and lead wires into the mounting surface, while using a supplied protective screen to prevent particular impingement. For airflow smoothing requirements within flight test applications, an optional rubber fairing is available. Modified versions of model 8515C are also available for wider temperature compensation. All units are shipped in special electrostatic discharge (ESD) packaging, for added protection during product shipment and handling.

Because of its uniquely high overload capability, high frequency response, very low base strain sensitivity and excellent temperature performance, model 8515C is ideally suited for small-scale wind tunnel testing models, helicopter or turbine blade surface pressure measurements, as well as aerodynamic surface measurements required during flight test.
