Description
The ACI Relative Humidity with Temperature Transmitter Room Series utilizes a thermoset polymer capacitive sensing element with a factory applied hygroscopic filter to deliver a proportional analog current or voltage output signal. The hygroscopic filter provides added resistance to moisture, dust, and other chemicals for greater long-term reliability. The RH Room transmitter features integral DIP switches for field selection of the proper output signal and supply voltage to meet your applications requirements. 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 must be powered with 13.5 to 24 VDC power source and can be ordered as either a two-wire 4-20 mA or 3-wire voltage output sensor. The temperature transmitter is installed on the back of the enclosure and must be mounted over a single gang junction box in the wall. There are two styling options in this series which should satisfy most commercial decors. Both styles feature four-way air‑ow to minimize self-heating. NIST Calibration Certificates are available for all RH TTM part series.

Features
The ACI Relative Humidity with Temperature Transmitter 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
Single point field calibration can be performed by using the increment and decrement calibration DIP switches to adjust your curve up or down in +/- 0.5% increments with each toggle of the corresponding switches
These enhancements provide increased flexibility and outstanding long-term reliability without the need to replace the sensors in the field
Duct configurations feature either a NEMA 4X or NEMA 3R enclosure and a conformally coated circuit board for increased moisture resistance in high humidity environments
NIST Calibration Certificates (Temperature and RH) are included for all TTM RH part series.
