A/RH3-CP-D Duct Relative Humidity, Thermistor Sensor by ACI

Description

The ACI Relative Humidity with Thermistor Duct Series utilizes a thermoset polymer capacitive sensing element with a factory fitted hydrophobic filter to improve its moisture resistance

• The sensing elements multilayer construction also provides excellent resistance in applications where dust, dirt, oils and common environmental chemicals are found
• The RH duct sensors include on board DIP switches which allow the user to select the desired output signal and can be powered
  by AC or DC power sources
• Each unit also contains 0%, 50%, and 100% test options to verify that the transmitter is both working and wired properly
• Field calibration can be performed by using the increment and decrement calibration DIP switches without the need to replace the sensing element
• These enhancements provide increased flexibility and outstanding long-term reliability without the need to replace the sensors in the field
• Duct configurations feature a weatherproof Euro style enclosure with a gasketed cover and conformally coated circuit boards for increased moisture resistance in high humidity environments
• The sensor is protected by a stainless-steel sintered filter
• Three point NIST Calibration Certificates are available
