The LevelRat non-fouling digital submersible level transmitter from Keller America has been upgraded to include better accuracy and dual output signals — one analog and one digital. Analog outputs include 4-20mA, 0-5 VDC, or 0-10 VDC, with RS485 digital communications opening additional options and compatibility with new and existing systems. The RS485 output uses the same modified Modbus communication protocol as Keller’s other digital transmitters. It makes direct connection to Modbus SCADA, PLC and RTU units possible, allows up to 128 transmitters to be connected on a single bus, and facilitates connection to a PC running CCS30 software, which gives users the ability to actively view real-time pressure/temperature changes, run software-assisted level logging and make adjustments to the analog output. 877/253-5537; www.kelleramerica.com.
