Sherborne Sensors, a global leader in the design and manufacture of sensors has released the T820 series, a new range of high precision, gravity referenced dual axis inclinometers for measurements in space constrained environments such as borehole or well logging and seismic studies. Available for ranges from ±14.5° to ±60°, they are Sherborne’s smallest diameter inclinometers at just 23 mm in diameter and 161 mm in length. The T820 Series includes the T823 with an environmentally sealed connector and cable system or theT825 with solder pin terminations. They can operate from a bi-polar input voltage range of ±12 to ±18 Vdc or single ended voltage range of 9 to 18 Vdc. A high level output of ±5 Vdc is achieved for the bi-polar supplied unit and 0.5 to 4.5 Vdc for the single ended version.The T820 Series sensors are made from stainless steel to prevent corrosion and to reduce angular errors that can be caused by the mechanical flexibility found in alternative aluminium alloy constructed sensors. They also have an innovative precision angular alignment capability for increased installed resolution. The inclinometers continue to deliver precision accuracy in temperatures ranging from -18 to 70o C and will survive temperatures down to minus 40o C.“Borehole logging for the drilling minerals or as part of environmental or geotechnical studies requires high levels of precision and accuracy,” explains Mike Baker, Managing Director of Sherborne Sensors. “The T820 series has been designed to operate in the smallest of areas and can withstand high levels of mechanical shock without any degradation in performance.”Sherborne Sensors can customise all of its inclinometers designs and manufacture to conform to specific customer requirements.
