Scaling is the process of taking a signal such as a voltage or current output from a sensor and applying calculations to present this signal in a more usable form in terms of engineering units, such as PSI, °F or %RH. There are three common techniques used in the data acquisition world including linear scaling, mapped scaling and formula scaling. All three methods have their place and time for use and will be described at length in this article.
The new Aero Weather Station from Omni Instruments bridges the gap between expensive, high end meteorological stations and lower cost hobby style systems, with an all in one, compact, monitoring system. Featuring accurate sensors and a robust aluminum construction, the Aero weather station is ideal for all climates including harsh conditions where lower cost system would typically fail. With a variety of mounting options, the Aero can be used in both permanent and temporary installations.
The weather station can be configured to your exact requirements with wind speed, wind direction, temperature, humidity and barometric pressure sensors.
The low power data logger powers the station with just two AA batteries and can power the system for a single year, removing the need for expensive solar panels and rechargeable batteries. Up to 600,000 readings can be stored in the units internal memory. Data is downloaded via the USB port located on the bottom of the logger and can export your data for analysis and graphing.
Omni Instruments LLC offers a variety of sensor solutions which can meet and exceed OSHA regulations for monitoring your crane.
Variable angle booms must have a system to inform the operator the angle of the boom, with an accuracy of around 1%. Our new DMI series digital inclinometers offer a 0.1° accuracy, far better than the 1% specified by OSHA, and a 0.01° resolution to ensure you know exactly where you boom is at all times. The DMI is very easy to install, either with its mounting holes or with the strong magnet, and features an easy to read LED display which can be located in the cab.
Wind speed is another important consideration, while ground conditions can seem quite calm, at the tip of the boom this could be a completely different scenario. The WWS Skywatch from Omni Instruments is an all in one wind speed sensor, indicator and external alarm controller. The indicator gives the operator a continuous picture of the conditions and the optional alarm output will inform the operator of programmable pre-set alarm conditions have been reached.
While modern cranes have the ability to inform the user of the exact load of the load they are moving, the reliability and accuracy of these systems can be questionable. The ET link, both wired and wireless, give you an exact reading of weight of the load you are lifting, no second guessing and wondering if your instruments are correct. The fast update and 0.25% accuracy up to 250 tonnes ensure that no matter you’re under hook crane lifting application, the ET link will give you up to the second reliable readings.
