Industrial mV/V measuring instrument
Description
The B6494 industrial measuring instrument for panel mounting is suitable, through its accuracy and easy readability, for numerous applications. Via the two 6-digit digital multi-function displays, the measured values and the status of the transistor outputs are indicated.
The connection and the parameterisation are usually performed by the customer for this model. Programming the instrument is menu-driven. All strain gauge measuring bridges (maximum 4 x 350 Ω parallel) with an output signal up to a max. ±4.0 mV/V can be connected.
Industrial mV/V measuring instrument, model B6494
The internal sensor supply is DC 5 V. Requests and parameterisation of different values are possible via the serial interface. The 4 transistor outputs enable the dropping below or exceeding of limit values to be monitored. In addition, a 0/4 ... 20 mA and a DC 0 ... 10 V output signal are available for analogue evaluation. Interfering signals can be eliminated by filter settings.
Special features
- Dual mV/V display
- 2x digital input and 4x digital output
- Integrated multiple signal outputs available
- Serial interface, RS-232 or RS-485
