Computer Interfaced Fluid Machines
Product Code : LSK-HAP-10582
Computer Interfaced Fluid Machines (SKU LSK-HAP-10582) is an interface and drive unit that connects fluid machines test equipment to a computer, logging sensor data over USB and controlling motor speed through a built-in three-phase inverter. It is intended for fluid machines and turbomachinery labs in engineering colleges, polytechnics and TVET institutes. Science Lab Supplies manufactures the interface at its Ambala plant (Plot 448, HSIIDC Industrial Area, Saha, India), supplying institutions, contractors and distributors on factory quotations.
Specifications
The interface unit’s drive, measurement and software features appear one per row below. In short, it conditions and digitises sensor signals for USB transfer, while a sensorless vector inverter gives variable-frequency three-phase output with slip compensation, derives motor torque and adds a second drive output and a switched mains output.

Applications and Experiments for Computer Interfaced Fluid Machines
Adding computer control turns manual pump and turbine tests into logged experiments: speed is set from software, readings are captured automatically and curves can be plotted immediately. This suits B.Tech fluid machines practicals, final-year projects and TVET instrumentation modules where data acquisition skills are taught.
- Logging pump or turbine performance at controlled motor speeds, for example on a Centrifugal Pump Module.
- Measuring motor torque without a separate sensor, compared with the band-brake Turbine Dynamometer.
- Exporting results to other analysis software through the interface driver.
- Teaching sensor signal conditioning and USB data acquisition.
The unit delivers three-phase mains power to motors; connect and operate it only under qualified supervision with the equipment correctly earthed.
Standard Scope of Supply
The Computer Interfaced Fluid Machines unit is supplied as a single unit as described above, with its inverter drive, outputs, multi-way sensor connector and interface driver. The computer and the fluid machines test sets it connects to are separate items listed on the quotation where required.
Packing, MOQ and Lead Time
You can ask for one interface or one for each fluid machines station in your lab. Packing, delivery time and price appear on the quotation for the quantity you specify, and the test equipment it will serve can be priced on the same document.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Nigeria, Kenya, Ghana, Ethiopia, Tanzania and Uganda. Describe the machines you want to connect on the contact page, place the interface beside them in the enquiry cart, or refer to the lab tender page for formal procurement.
Frequently Asked Questions
How does the unit connect to the computer?
Through USB. The interface conditions and digitises the sensor signals and transfers them to the computer, and works with both 32-bit and 64-bit computer operating systems.
Can it control motor speed?
Yes. Its three-phase inverter provides variable-frequency output under software control, with automatic slip compensation to hold a constant speed, plus a second motor drive output for another machine.
Who builds this interface unit?
Science Lab Supplies manufactures it at its Saha, Ambala factory in India, and handles the quotation and technical queries itself as the maker, without a reseller in between.
Can the data be used in other programs?
Yes. An interface driver allows the unit to link with other software packages, so logged results can be analysed outside the supplied environment, for example in a spreadsheet or a student project.
