20026944-80 is an 8531N wireless vibration sensor that combines an accelerometer, a data collector, and a radio into one compact, battery-operated device that measures both vibration and temperature data. It was designed for hash environment. It uses the Bluetooth® BLE-5 communication protocol, offering a simple, reliable, secure means of expanding condition-based maintenance into plant areas where the cost to install wired systems is prohibitive, making data available to existing process control, information systems. The Bluetooth® interface provides easy access to embedded configuration settings at the sensor installation. Applications include condition based monitoring, electric motors, oil and gas equipment, ICE powerplants, pumps for liquids, compressors, factory equipment, robots, cobots, autonomous guided vehicle, HVACR equipment. Compiles with ATEX/IECEx/US/CANADA IS CL I, DIV 1, GRP A, B, C, D, T4, CL 1. ZN 0, AEx is IIC T4 Ga, II 1 G, Ex is IIC T4 Ga (explosive atmospheres).
