Micro-Epsilon UK Ltd. - PRODUCT NEWS
Custom eddy current and draw wire sensors for subsea oil & gas applications
At this year's Instrumentation Scotland & Offshore Systems 2010 exhibition (8-9 September 2010) precision sensor manufacturer Micro-Epsilon (UK) Ltd (stand 703) will be showcasing a range of displacement sensors and non-contact temperature measurement products for subsea, oil & gas applications, including draw wire sensors, eddy current displacement sensors, thermal imagers and inline process temperature sensors.
Micro-Epsilon's wireSENSOR range of draw-wire (string pot) displacement sensors uses three main measurement methods: a multi-turn potentiometer, an incremental encoder or an absolute encoder. One of these devices is mounted onto the drum axle, converting the rotary motion of the drum into a signal that can be evaluated. The measured displacement can be output as an analogue current, voltage or potentiometric signal. For a digital output, there is a choice of HTL or TTL, with interfaces for most of the common fieldbus systems, including CANopen, SSI and Profibus.
As with traditional tape measures, the wireSENSOR series is capable of measuring around corners and edges. Micro-Epsilon supplies as accessories deflection pulleys, which deflect the steel wire in the desired direction. The sensors cover a measuring range from 50mm right up to 50m. Options are available for harsh environments (including subsea), with an IP67 version available.
Chris Jones, Managing Director at Micro-Epsilon (UK) Ltd comments: "Our draw-wire sensors are being used in a wide range of applications, from general industrial machinery and scissor lifts, through to more specific uses such as pneumatic and hydraulic systems, forklift trucks and subsea oil & gas systems. Our wireSENSOR range is very popular with machine builders and OEMs, who require low cost, robust, reliable sensing solutions that can be easily integrated into their customer's existing machine, components or control and automation systems."
Unique eddy current sensors
Visitors to Micro-Epsilon's stand will also be able to see the company's brand new range of eddy current ECT (Embedded Coil Technology) sensors. ECT is a technological breakthrough in eddy current sensor design and manufacture, which overcomes the previous limitations of using eddy current sensors.
Due to its ultra-compact design and by using new inorganic materials in its construction, the new eddyNCDT ECT sensors provide almost unlimited scope in terms of the external design and geometrical shape of the sensor. This means that sensors can be adapted for almost any use, including subsea, oil and gas applications.
Micro-Epsilon's eddyNCDT ECT sensors offer extreme mechanical robustness, resulting in longer service intervals and higher temperature stability. The complete circuit electronics are integrated into the sensor itself, providing a more compact solution for OEMs and machine builders. The sensors are suitable for harsh environments, including high vibration, impact shocks, high pressure/vacuum, and high operating temperatures up to 350 deg C. Sensors have also been produced with extremely low thermal drift and with temperature errors of less than 20ppm/K.
Non-contact temperature measurement
As well as displacement sensors, Micro-Epsilon will also be showcasing a range of non-contact temperature measurement products, including thermal imaging cameras and inline process temperature sensors.
After recently setting up a partnership agreement with Flir Systems UK, a leading supplier of infrared thermography systems, Micro-Epsilon is now able to offer the thermoIMAGER i series of handheld thermal imaging cameras, as well as its own inline process temperature sensors.
