A/RH2-TT1K-O-4X-2 Outside Air Humidity and Temperature Transmitter by ACI

Description

The ACI Relative Humidity with Temperature Transmitter Outside Air Series utilizes a thermoset polymer capacitive sensing element with a factory applied hydrophobic filter to deliver a proportional analog current or voltage output signal

• The hydrophobic filter provides added resistance to moisture, dust, and other chemicals for greater long term reliability
• The RH Outside Air transmitter features integral DIP switches for field selection of the proper output signal and supply voltage to meet your applications requirements
  • 0-5Vdc
  • 0-10Vdc
  • 4-20mA
• 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
• The temperature transmitter can be used as either a two-wire 4-20mA proportional output or as a 3-Wire voltage output transmitter that includes a 100 Ohm or 1K Ohm Class A, Platinum RTD
• All RH-TT Series Outside Air transmitters are mounted in a IP66/NEMA 4X enclosure with a 4.5" polycarbonate tube to protect the sensing elements from dust, rain, and snow
• These units should be installed under an eave or protective shield on the north side of the building (Northern hemisphere) out of direct sunlight
• The RH transmitter is conformally coated for added protection from moisture and other contaminants
• NIST Calibration Certificates are available for all RH TTM part series
