BT300S Variable Speed Peristaltic Pump
The BT300S Basic Variable Speed Peristaltic Pump delivers a flow range from 0.006 to 1690 mL/min, accommodating variable pump heads and tubing. It features essential functions like reversible direction, start/stop, and adjustable speed, along with advanced capabilities such as Time Dispense Mode and an Anti-Drip function. Enhanced connectivity is ensured through the MODBUS RS485 interface, enabling effective communication with external devices such as PCs, HMIs, or PLCs.
Functions and Features
- LCD displays rotating speed and operating mode.
- Membrane keypad.
- Reversible direction, start/stop control, and adjustable speed.
- Time dispense mode: automatically dispense by setting the duration of each dose, lag time between doses, and number of cycles.
- ±0.5% high-precision rotating speed control with 0.1 rpm resolution (0–100 rpm) and 1 rpm resolution (100–150 rpm).
- External logic level signals can control start/stop, direction, and dispensing functions. External analog signals can adjust the rotating speed. The signal is optically isolated.
- RS485 MODBUS interface for easy communication with external devices.
- Internal double-layer isolation structure; circuit board with conformal coating makes the pump dust- and moisture-proof.
- Anti-electromagnetic interference feature, wide input voltage range for complex power environments.
- Stainless steel enclosure, easy to clean, resistant to corrosion from acid, alkali, sodium, and organic solvents.
- Optional accessories: foot switch, pulse damper, leakage detector, and others.
