Intertech Development’s Micropulse provides clincal laboratory researchers with a solid-state alternative to mechanical syringes for the production of small, short pulses of various gases.

The high-accuracy, 145 x 52 x 35mm Micropulse contains a miniature heat exchanger and precision temperature control that can be fitted into process control circuits without adding volume, and delivers gases up to 1.75scc/m at STP.

The required flow during the pulse period is automatically controlled via an 8-bit digital interface by a PLC or other external controller.

The user can pre-set flow direction (inward or outward), volume-flow (cc/minute) or mass-flow (standard cc/minute) pulses over a wide pressure range.

Overall accuracy and repeatability of 0.1 per cent can be achieved over extended periods of fully automatic operation.

Advantages: no moving parts or pneumatic valves to stick or wear; no small gaps or orifices to get clogged; no compressed-air source is required; application can initiate a flow pulse automatically, at any interval; multiple flow values can be produced in quick succession, as required by application.

Engineering analyses of testing application requirements and expected savings at specified gauge R and R using Intertech test technology and customised software are available at no charge.
