Miniature sensors help subsea
exploration
Entran sensors are used in Datem's range of cone penetrometers, aimed at the geotechnical sector of the offshore survey market.
Entran miniature sensors supplied exclusively in the UK by Northamptonshire-based StrainSense are proving up to the challenge in a highly demanding application in geotechnical surveying Lincolnshire-based Datem is a leading supplier of electromechanical and software based design solutions, with geotechnical survey products forming a major part of its business

Torque measurement for couplings and drive shafts
The StrainSense Series 420 CDS system provides accurate measurement of shaft power, torque and rotary speed.
The Entran sensors are fitted into Datem's range of cone penetrometers, aimed at the geotechnical sector of the offshore survey market which primarily comprises companies acquiring data on behalf of the petrochemical and telecommunications industries.
Working at depths in excess of 200m, the penetrometers measure the resistance of the seabed to penetration and supply soil strength characteristics which allow the interpretation of subsea soil conditions.
The Entran sensor specifically measures pore water pressure, which enables a more reliable determination of stratification - identification of the materials present - and soil type than a standard penetrometer.

Interface takes transducers straight to PC
The new LCV-USB interface from StrainSense is a high speed, high accuracy unit to allow for millivolt, volt and milliamp output transducers to be connected directly into a PC.
These data then provide the results for direct geotechnical design.
Entran sensors, a subsidiary of Measurement Specialties, were specified for this application because of their small size - the penetrometer has less than 4mm diameter available to house the high pressure sensor - and their resolution, to enable the excess pressures generated during penetration to be distinguished from the background hydrostatic pressure.
Martin Steggar of Datem comments: "Our clients need the very highest levels of accuracy as the integrity of the subsequent designs relies to such a large extent on the data provided by the penetrometers during the site investigations.
"The exact stratigraphy of the subsea surface provides vital information to our clients, and so having a highly accurate and reliable miniature sensor in the penetrometer is key to the success of the site investigation.
"The Entran product has proved to be consistently reliable, robust and highly accurate in these highly demanding conditions".
"Using the Entran products has allowed us to significantly strengthen our product range, enabling us to further develop and meet the demands of our business".
Anthony Cross, Managing Director of StrainSense, adds: "This application demonstrates very clearly the strengths of the Entran range of miniature sensors - compactness, versatility, robustness and accuracy in a highly pressurised environment".
