The R/RH Series relative humidity transmitters (with resistive temperature output) utilize a capacitive sensing element to deliver a proportional analog output. This series features on board DIP switches which allow the user to select the desired output signal. In addition, field calibration can be performed by using the on board increment and decrement DIP switches. These enhancements provide increased flexibility and outstanding long-term performance. Duct and Outside Air configurations feature conformally coated circuit boards for moisture resistance. Several RTD and thermistor temperature sensing elements are available in this series.

The R/RH Series is covered by an industry-leading Five (5) year warranty, which can be found on www.workaci.com.
The GP Series has been designed to provide excellent accuracy and reliability in commercial, industrial, and process control applications. They feature a stainless steel construction with no o-rings, which makes them compatible with a wide range of gases and liquids. All units are accurate to +/- 0.5% or +/- 1% of full scale. The GP pressure transmitter offers a combined repeatability, hysteresis, and non-linear factor that is typically below +/- 0.15% of full scale. These devices are both EMC compliant and reverse polarity protected. They may also be ordered mounted in an optional NEMA 4 rated enclosure.

The GP Series is covered by an industry-leading Two (2) year warranty, which can be found on www.workaci.com.
The R/LP2 Series pressure transmitters incorporate a durable piezoresistive sensing element to enable low pressure measurements. Integrated temperature compensation with offset and span calibration enhances the performance of these devices and provides long-term reliability. An optional LCD provides an initial set up reference, trouble shooting assistance, and performance monitoring. Each unit offers field selectable outputs and additional ranges. The R/LP2 Series is calibrated using N.I.S.T. certified references to ensure a high level of accuracy.

The R/LP2 Series is covered by an industry-leading Five (5) year warranty, which can be found on www.workaci.com.
The R/DP2 Series is a line of low differential pressure transmitters that are capable of sensing full scale pressure ranges down to 0.1" of water column. Each R/DP2 pressure transmitter utilizes a high-quality Silicon Capacitive sensor to provide long-term stability and performance. Accuracy is +/- 0.3% of full scale over the compensated temperature range for most ranges (see Pressure Range Chart on reverse side). This is critical for optimizing building pressure. In addition to the requested span, most units are capable of being field adjusted to a maximum of three additional spans by resetting the internal jumpers. This series also offers the option of a preassembled pitot tube for ease of installation.

The R/DP2 Series is covered by an industry-leading Five (5) Year Limited Warranty. The warranty can be found on www.workaci.com.
The DBL Series Differential Pressure Switches are adjustable vacuum, pressure and differential pressure switches designed for both HVAC and Energy Management Applications. Due to the ease of calibration and adjustment procedures, these units will save you both installation time and money. The units have field adjustable setpoints and switching differentials. They will reset automatically. Each unit contains (1) SPDT contact rated for 1.5 Amps @ 250 VAC. All wiring connections are to be made with spade connectors and a maximum wire size of 16 AWG.

The DBL Series is covered by an industry-leading Two (2) year warranty, which can be found on www.workaci.com.
The CO and NO2 Series transmitters monitor carbon monoxide, or nitrogen dioxide, and are designed for the continuous monitoring of vehicle exhaust in non-hazardous areas. A wide spectrum, long life electrochemical sensor measures the amount of carbon monoxide or nitrogen dioxide in the environment. Both the Room and Duct transmitters are offered in a standard NEMA 1 rated ABS Polycarbonate plastic enclosure. An optional NEMA 4X watertight and dust proof enclosure is available with the room transmitter. Other options include an LCD display with (2) SPDT Form 1C relays and a buzzer.

The CO and NO2 Series are covered by an industry-leading Two (2) Year Limited Warranty. The warranty can be found on www.workaci.com.
The CO2-010-D monitors carbon dioxide from 0 to 2000 ppm for duct mount applications. They feature analog outputs (see order grid for output options) with a patented ABC Logic™ self-calibration system. The concentration of carbon dioxide is measured using a Single Beam, Non-Dispersive Infrared (NDIR) Absorption sensing method. They will indicate one of five approximate ppm levels. These units should not be used in environments such as greenhouses, wineries, breweries. They should also be avoided in areas where industrial sources of carbon dioxide are present or in applications where the space is left unoccupied for less than 4 hours a day.

The CO2-010-D is covered by an industry-leading Two (2) year warranty, which can be found on www.workaci.com.
We offer a comprehensive selection of general mounting configurations for Thermistors (see list above). These sensors provide a predictable and accurate output over the specified temperature range. Each sensor configuration is designed and manufactured for long-term quality and performance. Our OEM, ACI, incorporates standard features such as double encapsulation, and etched Teflon leads where applicable.

The Thermistor Series is covered by an industry-leading Five (5) year warranty, which can be found on www.workaci.com.
The A/ACS and A/ASCS are Solid State Current Switches with an adjustable trip point. The switches on these units are activated upon reaching a desired amperage setpoint. The Split Core design is ideal for retrofit applications and the mounting base is 35mm DIN Rail mountable. They include a Red and Green LED that indicate the "Status" of the switch contacts.
