Sensors for subsea oil & gas applications

21 July 2010

Micro-Epsilon (UK) has launched a range of displacement sensors and non-contact temperature measurement products for subsea, oil and 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 commented: "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."

Micro-Epsilon has also launched a 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.

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.
