Inertial Aerosystems have introduced a new low cost range of, slim line Tilt Sensor boards, manufactured by U.S. based Applied Geomechanics. Designated the Tulip range it consists of 6 models which are 4-20mA current loop compatible with programmable controllers and similar factory automation instrumentation. Tulip is current loop powered and measurements can be made over long cable lengths using an economical 2 wire pair.

These innovative products, weighing 15g, are designed to measure angular tilt where space and weight are at a premium. They are can be mounted inside pressure housings, well logging tools or on any machine or structure, and can be configured for vertical or horizontal mounting.

Tulip comes in 3 angular ranges. Firstly a High gain version of + or - 10° (20° span) with a resolution of 0.005° and 0.01° repeatability.

Secondly a Standard version of + or - 25° (50° span) with a resolution of 0.01° and a 0.02° repeatability. Thirdly a Wide angle version of + or - 50° (100° span) with a resolution of 0.02° and a <0.04° repeatability.

The Tulip's electrolytic sensor has no moving parts which means virtually no maintenance or calibration. The operating temperature range is -40 to 85°C, and the sensor has a built in thermistor for temperature modelling. Each model comes with a calibration sheet showing variation with non linearity.

Applications include Well logging tools, Factory processing and Control and Structural monitoring.
