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 supports various resistive temperature sensors like thermistors or RTDs, offering flexible remote sensing solutions.
· Available in multiple wiring harness lengths for versatile installation.
· Features single-point field calibration with increment and decrement dip switches for precise adjustments.
· Equipped with conformally coated circuit boards for enhanced durability in high moisture and mildly corrosive environments.
· Comes with an IP66/NEMA 4X rated enclosure and a vinyl cap for sensor protection in wash-down applications.
· Includes NIST Calibration Certificates for both temperature and RH.

FEATURES

· Reverse polarity protected RH supply voltage with multiple load options.
· Flexible RH output signals: 4 mA to 20 mA (2-wire) or 0 V dc to 5 V dc / 10 V dc (3-wire).
· High accuracy: ±1% over 20% RH range, ±2% or 3% from 10% to 95% RH.
· Wide RH measurement range: 0% to 100%, with an operating range of 0% to 95% RH (non-condensing).
· Robust operating temperature range: -40°C to 60°C.
· Stable performance: Less than 2% drift over 5 years, 0.5% RH repeatability, and 0.1% RH sensitivity.
· Quick response time: 20 seconds typical (T63).
· Screw terminal blocks for secure connections, compatible with 16 AWG to 26 AWG wire sizes.
