Wall/DuctSpaceOutside Air (OSA) Overview Specifications
Operating:Room: -10 to 150°F (-23 to Minco humidity and humidity/
industrial temperature transmitters aredesigned using an advanced microprocessor. Digital signal
processing allows these transmitters to precisely match the
characteristics of the humidity sensor to a wide range of RH
and temperature values found in the many applications the
product serves. The humidity sensor is composed of an integrated circuit (IC)with a stable polymer element and platinum RTD that is used for
temperature compensation. This sensor offers outstanding resist-
ance to airborne contaminant and chemicals, and is protected
by a sintered stainless steel filter which resists condensation.• Wall/Duct/OSA mounting configurations
• Accuracies of ±1% or ±2% RH
• Temperature compensated
• Temperature output option
• Two-point field calibration
• NIST traceable calibrations Ambient Temperature: 6 5°C), non-condensing.Wall/Duct/OSA: -10 to 185°F (-23 to 85°C), non-condensing.Storage:Room: -58 to 150°F (-50 to 6 5°C), non-condensing.Wall/Duct/OSA: -58 to 185°F (-50 to 85°C), non-condensing. Supply voltage: 9.5 to 35 VDC, non-polarized. Voltage effect: ±.001% of span/volt from 9.5 to 35 VDC. Loop resistance: The maximum allowable resistance of the signal-carrying loop, including extension wires and load resis-
tors, is given by this formula: R Ω .
loopmax = (V
supply - 9.5)/0.02 AMPS.For example, if supply voltage is 24 VDC, the loop resistance
must be less than 725 Adjustments: Zero and span field adjustments, non-interacting. Time Constant: 50 seconds in slow moving air. Connections: Screw terminals (22-14 AWG wire). Weight: Minimum output current: Room: 0.19 lb (.084 kg).
Wall/Duct/OSA: 1.20 lb (0.55 kg). 3.5 mA
Applications
Maximum output current: 23 mA. Building environmental control systems (HVAC), hospitals, foodstorage, warehouses,
clean rooms, pharmaceutical, freezers,
drying equipment, and emissions monitoring.
