Cảm biến áp suất gió ZPS (Standard and Low Ranges)

Features & Options

• 10 Pressure Ranges & Three Outputs – All Field Selectable
• Standard Range (-5 to +5 WC or -1,250 to +1,250 Pascals) or Low Range (-1.0 to +1.0 WC or -250 to +250 Pascals) 
• Free NIST Certificate Included with Each Pressure Unit
• Snaptrack, DIN Rail or Surface Mounting

Measuring building pressure, air velocities and volumes doesn’t get any easier than with the DELTA EZ Pressure Sensor. The revolutionary 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. 

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 also features 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 regardless of which individual pressure range is selected for output to the system controller.
