Inertial Aerosystems is introducing a new low-cost range of Tulip slimline tilt sensor boards, manufactured by USA-based Applied Geomechanics. The Tulip range consists of six models that are 4-20mA current loop compatible with programmable controllers and similar factory automation instrumentation. Each board is current loop-powered and measurements can be made over long cable lengths using an economical two-wire pair. These innovative products, weighing 15g, are designed to measure angular tilt where space and weight are at a premium. They 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 boards come in three angular ranges: a high-gain version of +/-10 degrees (20-degree span) with a resolution of 0.005deg and 0.01deg repeatability; a standard version of +/-25 degrees (50-degree span) with a resolution of 0.01deg and a 0.02deg repeatability; and a wide angle version of +/-50 degrees (100-degree span) with a resolution of 0.02deg and <0.04deg repeatability.
The Tulip's electrolytic sensor has no moving parts, which means virtually no maintenance or calibration. The operating temperature range is -40 to 85degC and the sensor has a built-in thermistor for temperature modelling. Each device comes with a calibration sheet showing variation with non-linearity.
Applications include factory processing and control, well logging tools, and structural monitoring.
