Compact Pressure Sensor
Measuring building pressure and air velocities or volumes doesn’t get any easier than with the Automated Logic Compact Pressure Sensor. The mounting system allows for 2.75” snaptrack, DIN rail, or surface mounting, and the three outputs and 10 pressure ranges are field selectable by simply turning the rotary switch and pressing the “Next” button. The auto-zeroing process is also very easy — simply turn the rotary switch to zero, push the button for five seconds, turn the rotary switch back to your pressure range and walk away
Besides being easy to set up and install, it is also accurate, rugged, and economical. The heart of the unit is a micro-machined silicon pressure sensor with excellent accuracy, repeatability, and stability.
The unit features a rugged NEMA 1 rated enclosure with short circuit proof outputs and reverse polarity protected inputs to perform under real world conditions
The LCD display helps with troubleshooting because it displays the actual differential pressure over the entire operational range (-5 to +5 inches W.C. or -1,000 to 1,000 Pascals) regardless of which individual pressure range is selected for output to the system controller
