Inclinometer Packaged To Be Compact, Ideal For OEM Applications

Automated Control Engineering is the exclusive national supplier of the newest ASM product. ASM has introduced its smallest addition to the POSITILT® inclinometer series that is available in single and dual axis versions. By using MEMS technology, this new inclinometer PTAM20 series is packaged into a very compact, flat housing making it ideally suited for OEM applications.

The measurement range for the single axis version is available from +/- 15° to +/- 180°, in increments of 15°. For the dual axis version, the measurement range is available from +/- 15° to +/- 60°, in increments of 15°. The resolution is 0.05° and the linearity is up to +/- 0.5°. Several analogue output types are available that include: 0.5-4.5 V, 0.5-10 V and 4-20 mA. Each version offers high shock resistance and is rated IP60 which is suitable for many instrumentation functions.

Absolute Encoders from Stegmann

DAYTON, OH – SICK STEGMANN, INC. introduces AFS60 Singleturn and AFM60 Multiturn Absolute Encoders. With the help of a simple programming tool, users, system integrators and distributors can self-configure any programmable version of the AFM/AFS60 via a PC or laptop in seconds, without the need for an external voltage supply. Resolutions up to 262,144 singleturn and 4,096 revolutions multiturn, zero point or offset and the counting direction can be freely selected.

Their innovative design allows a 30 mm distance between bearings which decreases vibration, increases bearing life, and delivers exceptionally smooth operation even at the maximum operating speed. Coupled with a robust Nickel code disc, they are particularly suited to determining position, angle, speed or acceleration in harsh application environments requiring both maximum accuracy and reliability. These revolutionary encoders come with an option of a pluggable outlet that can be used as either a radial or axial cable outlet which reduces installation depth and provides simple cable replacement, if needed. The AFM60 multiturn provides 30-bit resolution, and the AFS60 singleturn provides 18-bit resolution, at speeds up to 9,000 rpm. They are rated for operation in temperatures ranging from –20 …+100°C, and offer up to 70 g/6 ms resistance to shock and up to 30 g/10 … 2000 Hz resistance to vibration.

DC-Operated High Precision Servo Inclinometers

Sherborne Sensors has announced the North American launch of Series T435, a single axis, high-precision, closed loop gravity referenced servo inclinometer family, designed for down-hole logging applications, or for use in areas where space is at a premium.

With a form factor measuring only 1.6 in. (40.6mm) high and less than 1.46 in. (37mm) in diameter, sensors can be stacked for simultaneous X & Y measurement of tilt angles. Models are available in ranges from ±3° to ±90°. Series T435 offer a high-level DC output signal, proportional to the sine of the available angle of tilt. Units are fully self-contained, and able to connect to a DC power source and readout or control device for a complete operating system. The T435 series are also extremely rugged, and can withstand a 1500g shock event. Solder pin terminations are standard.

Dual Axis, Gravity-Referenced Servo Inclinometers

Sherborne Sensors Limited has announced the North American debut of its Series T233/5, a family of compact, dual axis (x and y), gravity referenced servo inclinometers, designed for use in aggressive military, commercial and industrial applications where a high level of accuracy and resolution is required.

Series T233/5 offers a ± 15 VDC input voltage, and ± 5 VDC output signal, with self-test on both axes. Units are capable to a resolution of 0.1 arc second. Each axis is fully conditioned, with total electrical isolation between axes. Models are silicone oil and electric damped, and available in ranges from ±1° to ±90°. Series T233/5 offers either solder pin leads or a connector as standard, and delivers a complete, cost effective, high-accuracy measurement system.

Dual Axis Inclinometer Sensor

Minneapolis, Minn.—TURCK introduces a new dual axis inclinometer sensor for angular tilt detection. These sensors feature compact rectangular housings and may be mounted at ±10, ±45, ±60 and ±85 degree angles. Inclinometer sensors may be used in a wide variety of industries to solve unique feedback requirements where the customer needs to level platforms, control tilt angle or control a dancer.

The new TURCK inclinometer measures angular tilt in reference to gravity. At the heart of the TURCK inclinometer is a MEMS (micro-electro-mechanical system) device, which incorporates a micro-electro-mechanical capacitive element into the sensor that utilizes two parallel plate electrodes, one stationary and one attached to a spring-mass system. Movement causes acceleration that produces deflection in the non-stationary electrode. This results in a measurable change in the capacitance between the two plates that is proportional to the angle of deflection. These signals are conditioned to provide two analog outputs (0.1 to 4.9 VDC) or two current outputs (4 to 20 mA).

The microboard design in the MEMS technology allows for a compact, precise inclinometer in a very robust, industrialized package. The inclinometer is IP 67 rated, with a temperature range of -30 to 70° C that permits its use in many applications, including:

* Machine engineering: levers, pedals, flaps, mixing machines, hydraulic jacks
* Commercial machines: diggers, cranes, rotary tables, bulldozers, road construction machinery
* Vertical and horizontal drills used in tunnel and road construction and immersion equipment
* Offshore plants: platforms, cranes
* Furniture: hospital beds, dental chairs, fitness machines, wheelchairs
* Conveyors
