These Masterflex® L/S® MasterSense® drives feature high precision, repeatable flow control, and reliable performance, you can have it all in one small footprint even more bench space. Open-head sensor technology stops the drive motor when pump head is opened, or connect it to a remote leak detector to stop the pump anytime a leak is detected in the fluid path.
Brushless, maintenance-free motor provides ±0.1% speed control accuracy with 6000:1 turndown ratio. Bidirectional flow and self-priming capabilities allow for smooth, seamless operation.
Pressure sensor integration feature brings single point pressure values to the pump interface in real time. Provide extra reliability to your process by configuring high/low set point alarms. Alarm can be set to trigger either a warning and/or pump shut off. Order required accessories for simple plug and play functionality: choose the MasterSense® MP1 adaptor kit for single-use applications, the MasterSense® MP30 reusable pressure transducers for repeat use.
MasterflexLive® is a secure, cloud-enabled platform for monitoring Masterflex pumps; get real-time notifications of pump parameters including speed, flow rate, dispense volume, and more. You can monitor critical processes running 24/7 without the need for onsite personnel while notifications alert you to operating conditions and error messages. Internet connection via Wi-Fi or standard Ethernet (RJ45) jack on rear of drive.
