HOBO Differential Air Pressure Transducer
- Expedited repair and warranty service
- Lifetime technical support
- More
- Available in three installation configurations
- Field-selectable sub-ranges
- Sensor has IP65/NEMA 4 rating
Overview
The HOBO differential air pressure transducer sensor measures either air pressure or velocity with the flip of a switch. Available in three installation configurations (duct, panel, or universal). Duct and panel models have two pressure and velocity range options: 0-1" WC / 0-3,000 ft/min or 0-10" WC / 0-7,000 ft/min, with seven field-selectable sub-ranges for pressure and eight for velocity. All variants are available with and without display. This sensor has an IP65/NEMA 4 environmental rating.
Requirements (Logger Specific):
- 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)
- Media Compatibility: Dry air or inert gas
- Input Power: 12-30VDC, or 24VAC nominal
- Output Field-selectable: 2-wire, loop-powered 4-20mA (DC only, clipped and capped) or 3-wire 0-5V/0-10V
- Pressure Ranges: Unidirectional: 0.1/0.25/0.5/1.0” W.C. F.S. (25 pa/50 pa/100 pa/250 pa, F.S.), switch electable; Bidirectional: ±0.1/±0.25/±0.5/±1.0” W.C. F.S. (±25 pa/±50 pa/±100 pa/±250 pa, F.S.), switch selectable
- Response Time: Standard: T95 in 20 sec, Fast: T95 in 2 sec, switch selectable
- Mode: Unidirectional or bidirectional, switch selectable
- Display: (option) Signed 3-1/2 digit LCD, indicates pressure, overrange indicator
- Proof Pressure: 3 psid (20.6kPa)
- Burst Pressure: 5 psid (34.5kPa)
- Accuracy: ±1% F.S. of selected range (combined linearity and hysteresis)
- Temperature Effect: 1" 0.05%/°C; 10"
- Zero Drift: (1-year) 1" 2.0% max.
- Zero Adjust: Pushbutton auto-zero and digital input (2-pos terminal block)
- Operating Environment: 0°- 60°C (32° to 140°F); 0 to 90% RH non-condensing
- Fittings: Brass barb; 0.24” (6.1mm) o.d.
- Physical: UL 94 V-O Fire Retardant ABS
- Available in three installation configurations
- Field-selectable sub-ranges
- Sensor has IP65/NEMA 4 rating
