Measuring 145 mm x 52 mm x 35 mm, the MicroPulse module debuts as an alternative to mechanical syringes. It contains a miniature heat exchanger and precision temperature control that can be integrated into process-control circuits without adding volume. MicroPulse delivers gases up to 1.75 scc/m at STP. Required flow during the pulse period is automatically controlled via an eight-bit digital interface by a PLC or other external controller. Users can pre-set flow direction, volume-flow, or mass-flow pulses over a wide pressure range. Overall accuracy and repeatability is 0.1%. InterTech Development Co., Skokie, IL. (847) 679-3377.
