英文簡介
8250 ProcessPro® Level Transmitter
Signet 8250 Level Transmitters are compatible with the Signet 2250 Level Sensor and 2450 Pressure Sensor. The instrument is available in field and panel mount configurations, single or dual-channel input and equipped with one 4 to 20 mA output, fully scaleable and reversible for each input channel. The unit also features two relays, plus the ability to support two additional externally mounted relays (for a total of four). Relay operations is selectable for High, Low, Window or Off, and includes fully adjustble hysteresis and trigger time delay.
The unit also has the ability to accept other level sensors with 4 to 20 mA output via the Signet 8058 Signal Converter. Automatic level-to-volume conversion allows display and control of tank level and/or volume in units such as gallons, kilograms, feet or meters. Simply enter the dimensions of your tank or vessel, and the instrument will calculate volume from the level measurement.
Fields of Application:
- Continuous level and/or volume monitoring
- Local or remote display
- Fill start/stop control
- Pump protection
- Inventory Management
- Storage Tank Monitoring
- Pump Station Control
- Plating Lines
- Neutralisation Tanks
Advantages:
- Compatible with Signet 2450 Pressure Sensors
- Single or Dual Channel Input
- 4 to 20 mA Outputs Fully-Scaleable, Reversible and Assignable to Either or Both Channels (8250-3X versions)
- Advanced Relay Control
- Output Simulation
- Manual (up to 10 pts.) and Automatic Level-to-Volume Conversion
- Display Level, Volume or Both
- Units for Level: ft., in., m, cm, %
