DESCRIPTION

· The ACI RH TT Remote Probe Series utilizes a thermoset polymer capacitive sensing element with a hydrophobic filter for accurate RH and temperature measurements.
· It offers flexible remote probe wiring harness lengths ranging from 0.91 m to 6.096 m.
· Features single-point field calibration via increment and decrement dip switches, with each toggle adjusting ±0.5% RH.
· Calibration can also be performed using Zero and Span potentiometers for current or voltage output devices.
· Conformally coated circuit boards enhance reliability in high moisture and mildly corrosive environments.
· The enclosure is IP66/NEMA 4X rated for moisture and corrosion resistance.
· Includes NIST Calibration Certificates for both temperature and RH.

FEATURES

· RH Supply Voltage: 15 V dc to 40 V dc / 18 V ac to 28 V ac (reverse polarity protected).
· RH Output Signal: 4 mA to 20 mA (2-wire, factory default) or 0 V dc to 5 V dc / 0 V dc to 10 V dc (3-wire, field selectable).
· RH Accuracy: ±1% over 20% RH range (20% to 90%), ±2% or 3% from 10% to 95%.
· RH Measurement Range: 0% to 100%, with an operating range of 0% to 95% RH (non-condensing).
· Operating Temperature Range: -40 °C to 60 °C (-40 °F to 140 °F).
· RH Response Time: 20 seconds typical.
· TT Supply Voltage: 8.5 V dc to 32 V dc (reverse polarity protected).
· TT Output Signals: 4 mA to 20 mA (2-wire loop powered) or 1 V dc to 5 V dc / 2 V dc to 10 V dc (3-wires).
