Universal isolator – 400 calibrated measuring ranges

Tilt sensor with shock compensation Sensor specialist FSG presents new PE-MEMS…/GS70 series tilt angle sensors for monitoring the inclination of construc- tion machinery and measuring tilt angles on ship platforms, working platforms or oil and gas rigs.The two-axis devices fea- ture the proven MEMS technology (micro-electromechanical measuring systems) and ensure high-precision, redundant measurements. An additional gyroscope compensates me- chanical shock. GS70 sensors gauge x-axis and y-axis angles in a measuring range of ±60° and achieve accuracies between ±0,05° and ±0,3° depending on angle range. The housing is made from passivated aluminium.The devices are designed for a temperature range between -40°C and +80°C and meet all technical safety requirements according to the IEC stand- ards 61508 (SIL 2) and EN 13849 (PLD). GS70 sensors are available for cable connection with IP68 ingress protection or with a plug connector and IP67 ingress protection. A CAN bus interface supports CANopen and the CANopen safety protocol for signal output. Mecosa is the sole agent for FSG Fernsteuergeräte in South Africa.

‘When very good is good enough’ – with this commendation, high-endmanufacturer Knick presents its new BasicLine isolation amplifiers which allow for extensive use in economically sensitive large-volume installations thanks to an optimised price/ performance ratio.The BL 570 isolator sup- ports reliable current and voltagemeasure- ment as well as standard signal conversion. The multi-talent is also suitable for measuring bipolar direct currents/voltages and enables individual adjustment of any measured voltage ranges between ±20 mV

and ±200 V. Currents up to 100 mA can be measured directly. Larger cur- rents are picked up via an external shunt resistor. The BL 570 features more than 400 factory-calibrated switchable measuring ranges that cover most practical scenarios – readjustments are not necessary. Featuring an offset correction function, it can even convert signals with an offset into standard signals. Thanks to an integrated wide-range power supply the isolator can be operated both at 24 Vdc supplies and 100..230 Vac mains supplies globally. Strictly concentrating on basic functions, leaving all ex- tras aside, Knick has tailored BasicLine devices to mechanical engineering companies that need precise and reliable yet cost-optimised isolators for large-scale applications. Notwithstanding the attractive price scheme, the devices feature Knick’s characteristic high level of manufacturing quality and precision as well as complete galvanic isolation.
