Loop Powered Sensors... 4-20 mA output signal
Product Announcement from Meggitt Sensing Systems - Wilcoxon Research
Meggitt Sensing Systems - Wilcoxon's loop powered sensors (LPS™) are an accelerometer and vibration transmitter in one industrial housing! LPS™ provide a 4-20 mA output signal proportional to the overall vibration level. 4-20 mA sensor output is commonly accepted by process control systems such as programmable logic controllers (PLC) or distributed control systems (DCS) for the most cost effective continuous vibration monitoring. If you already have a process control system that accepts 4-20 mA inputs - like a PLC or DCS network - you are already taking data points on pressure, temperature, or maybe flow. Now you can send vibration data to your PLC or DCS as well. By connecting into process control systems, you are able to perform predictive maintenance on machinery without the investment and learning curve associated with traditional vibration monitoring systems with data collection boxes and custom software. The LPS™ Series is ideal for industrial, commercial, and municipal facilities that all benefit from condition based monitoring and predictive maintenance programs. If physical plant assets are doing the work to process a product, then increases in productivity and efficiency can be realized with a continuous online machinery health monitoring program. Some of the most common processes to benefit from the 4-20 mA vibration sensors are pharmaceutical, food and beverage, brewing, water and waste water, petrochemical, pulp and paper, and power generation facilities. The LPS™ Series is effective for vibration monitoring of pumps, motors, fans, cooling towers, compressors, and gear boxes. Applying predictive maintenance techniques to these operations and machines can result in significant maintenance expense reductions.
