Transmitter box converts d.c. signals to other d.c. signals
Article Abstract:
The 610T Series of transmitters from Acromag Inc provide isolation and output-proportional DC current or voltage signals. The 610T incorporates an internal microcontroller that automatically senses the input source type and selects the optimum performance range for zero and full-scale input values. The output values are adjusted by pushing 'up' and 'down' buttons on the front panel. It can accept input signals of 0 to 100 mA DC and plus/minus 100 VDC or supply 0 to 20 mA DC or 0 to 10 VDC outputs.

Membrane air dryer takes dewpoint down to 35 degrees F
Article Abstract:
The SMD Series air dryers from the Balston Filter Div of Parker Hannefin employ a coalescing technology in generating clean and dry compressed air with constant dewpoint at 35 F. The SMD line has 14 different models covering the range from 25 to 600 scfm for inlet air from 60 to 140 psig. The air is pretreated by a coalescing filter that knocks out oil and water droplets while water vapor passes through the hollow fibers of the membrane.
