Pressure Sensor for critical dosing and dispensing

Intertronics has today introduced a new pressure sensor which offers high accuracy monitoring in an innovative design suited to critical dosing and dispensing applications. Compact and easily installed into the fluid path by means of standard luer lock fittings, the flowplus16 pressure sensor measures the pressure of the liquid being dispensed or dosed, and provides precise monitoring of material flow.

Useful in many analytical and laboratory situations, this precise monitoring information is also valuable in production environments where it can detect irregularities caused by air bubbles in adhesives which would disrupt tight tolerance dispensing on medical devices or visual displays, or identify a blockage building up in filled fluids, so enabling corrective action to be taken.

Accurate in-line pressure sensing can deliver important quality assurance in a whole range of automatic processes; for example, in medical, pharmaceutical and semi-conductor manufacturing, as well as the wider areas of process control.

One of the smallest piezo-resistive pressure sensors available, the maintenance free flowplus16 features an inert fluoropolymer internal coating which provides a smooth and consistent fluid pathway with no internal dead space. Integrating a micro-chip which converts the pressure sensing to a standardised 0-10V digital output signal, the compact sensor detects any pressure fluctuations so that problems can be identified at an early stage, e.g. clogging, micro-bubbles or variable pressure feed. Constant readout via a standard connector provides verification of correct dosing or dispensing and may be simply integrated into existing PLC control systems providing temperature compensated readings, without complicated calibration, in a user friendly package.

flowplus16 can operate with flows of up to 100ml/min at pressures of 0-16 bar and between 15°C to 45°C.

“When you absolutely have to know your process is right every time, the flowplus16 provides assurance, process reliability and reduced downtime,” comments Peter Swanson, M.D. of Intertronics.
