Overview
The Babbitt LS8000/R Rev 4 is a receiver circuit board engineered for the LS8000 remote-mounted radio frequency (RF) level switch system. The receiver board is wired to the supply voltage and has all the necessary calibration adjustments, failsafe and time delay adjustments, and relay output. This PCB serves as the control and sensing hub, receiving signals from the probe transmitter across distances up to one mile and providing relay outputs for automated tank-level control in liquid and dry-material applications.
Key Features
- Remote mounting capability: The receiver board can be mounted up to a mile from the transmitter.
- On-board protection: Every standard unit has an on-board fuse and surge suppressor to protect the circuitry from power surges.
- Adjustable calibration: All the necessary calibration indicators are on-board so all you need to calibrate the LS8000 is a small screwdriver.
- Modular design: The modular electronics make trouble shooting and repair a snap.
- Static suppression: A static suppression circuit protects against hostile bin environments created by static-prone materials such as plastic pellets.
Technical Specifications
- Input Voltage: 110VAC (±15%), 50/60 Hz
- Power Consumption: 3 watts, standard
- Fuse Rating: 250 mA (onboard)
- Relay Output: 3 SPDT relays, 1 form C contact per relay
- Signal Connection: Twisted shielded pair (Belden 8761 or equivalent)
- RF Frequency: Approximately 1.3 MHz
- Revision: Rev 4
Typical Applications
The LS8000/2 is specifically designed to automatically fill or empty a tank, hopper or sump. The LS8000/R receiver board is used in:
- Tank and hopper level monitoring systems
- Sump and reservoir control
- Dry-material level sensing (powders, pellets, flakes)
- Liquid-level control in process tanks
- Auto-fill and auto-empty applications in industrial fluid management
