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
