EQUIPMENT Bin Level Sensor + TECHNOLOGY The SmartBob AO level sensor features an integrated 4‐20 mA analog output to a PLC for monitoring bin level measure‐ ment data. A simple push‐button user interface built into the SmartBob AO circuitry is used to configure the set‐ tings for each SmartBob AO. To set up the SmartBob AO, the user opens the device to access the keypad, and steps through a series of push‐button set‐ tings to set the interval timer, units of measure, 4 mA and 20 mA drop dis‐ tances, maximum drop distance, and Construction Software the Relay 1 and 2 functions. Once setup is complete, measurement data is sent directly to a PLC, with all settings for the bin saved in the non‐volatile mem‐ ory of the SmartBob AO. Other benefits of the SmartBob AO include the output of a 22 mA error signal if the SmartBob AO should encounter a "stuck top" or "stuck bottom" condition and a soft start feature that reduces wear on the motor. BinMaster, Dexter + Chaney launched a new, web‐based version of Spectrum Construction Software. The latest version of Spectrum software, al‐ ready used by thousands of contractors for construction business management, is a full‐featured web‐based product. The 14th ver‐ sion is accessible via any web browser from a location using any In‐ ternet‐connected device. The browser‐based functionality drove a significant improvement in usability. Spectrum v14 can be de‐ ployed by the client on‐premise or customers can also choose a completely cloud‐based option and never worry about software up‐ dates or hardware requirements. Running in a browser simplifies IT infrastructure and reduces costs, notes the company. The user saves time and money on setup, hardware and internal support; even workstation requirements are low since all processing occurs on the server. Spectrum eliminates the need for third‐party soft‐ ware and additional hardware that other programs require to run on the Internet.
