Overview
A transducer sensor that can measure either air pressure or velocity with the flip of a switch. Available in the universal configuration, with pressure and velocity range options: 0-10" WC / 0-7,000 ft/min, with seven field-selectable sub-ranges for pressure and eight for velocity. Available with display. This sensor has an IP65/NEMA 4 environmental rating.
Requirements for use with specific data loggers:
- HOBO MX1100 series: a 0-5 Volt DC input cable (SD-VOLT-05) and external power provided by an AC adapter (AC-SENS-1)
- HOBO U12, UX120-006M, or ZW series: a 0-5 Volt DC input cable (CABLE-ADAP5) and external power provided by an AC adapter (AC-SENS-1)
- HOBO RX3000: an analog input module (RXMOD-A1)
- HOBO U30: an analog input module (VIA)
- HOBO H22: an analog input module (S-FS-CVIA)
Features
- Switch-selectable ranges and scales reduce setup time
- High reliability sensor technology for long-term, maintenance-free operation
- Monitors positive and negative pressure for application versatility
