BQ80S Micro Flow Variable-Speed Peristaltic Pump
1 Introduction
BQ80S is a portable micro flow variable-speed peristaltic pump. It provides
flow range from 0.005 to 64 mL/min with variable pump heads and tubing. It
offers not only basic functions such as start/stop, reversible direction and
adjustable speed, but also Time Dispense Mode to dispense fluid by setting
the duration time for each dose. With standard RS485 MODBUS interface,
it is easy to communicate with external device, such as PC, HMI or PLC.
2 Functions and Features
•Simple operation, portable size, easy to install. Suitable for
equipment as an ancillary device and for laboratory use.
•0.5% high precision rotating speed control with 0.1 rpm speed
resolution. Speed range 0.1-80 rpm.
•Four-digit LED displays working speed and control mode.
•Membrane keypad.
•Reversible direction, start/stop, adjustable speed.
•Time dispense function. Repeat dispensing by setting the dispense
duration time.
•Plastic housing, embedded design to work independently.
•The circuit board with conformal coating makes it dust-proof and
moisture-proof.
•External logic level signal can control start/stop, reversible direction
and time dispense function. The control signal is optically isolated.
•External logic level signal: 5V (default), 12V or 24V.
•MODBUS RS485 interface, easy to communicate with external
control devices.
•Optional footswitch or timer for dispensing fluid.
