Product Introduction
The VEGA VEGAMET 842 is a field-mounted controller and display instrument for two continuously measuring 4–20 mA sensors. It supplies power to compatible sensors, processes measurement signals, and provides local indication and control outputs for level and flow applications.
Key Features
- Two Sensor Inputs: Connects up to two 4–20 mA sensors.
- Large Backlit Display: Provides clear readings, with backlight color changes according to instrument status.
- Pump Control: Supports pump switching and pump management functions.
- Flow Totalization: Calculates and accumulates flow values for suitable applications.
- Bluetooth® Operation: Allows configuration using a smartphone, tablet, or PC.
- Multiple Outputs: Two 0/4–20 mA current outputs and three operating relays; a fail-safe relay can replace one operating relay.
- Rugged Housing: IP66/IP67 protection and Type 4X enclosure rating for demanding field conditions.
Applications
- Water and Wastewater Treatment: Monitoring tank levels and controlling pumps.
- Pumping Stations: Managing pump switching based on level thresholds.
- Open-Channel Flow Measurement: Processing signals from suitable sensors installed at channels and weirs.
- Reservoirs and Storage Tanks: Displaying measurements and monitoring high- or low-level limits.
- Differential Level Monitoring: Calculating differences between two compatible measurement signals.
- Process Monitoring: Calculating sum and average values and transmitting signals to external control systems.
Technical Highlights and Selection Considerations
The VEGAMET 842 combines local display, signal processing, relay control, and Bluetooth® setup in a single field instrument. Its two sensor inputs also support calculations such as difference, sum, and average, depending on the application configuration.
Before ordering, confirm the sensor output, number of measurement points, required control functions, relay configuration, current output requirements, power supply, and environmental conditions. For hazardous areas or safety-related applications, verify the approvals and exact configuration.
