The Hx-68P3 Series Outside Humidity and Temperature Transmitter measures and transmits outside relative humidity (RH) from 0 to 100% and temperatures from -40 to 140F (-40 to 60C). In addition to RH, the transmitter offers selectable parameters including dew point, wet bulb temperature, and enthalpy.

The Johnson Controls humidity transmitter is based on a new ''state of the art'' humidity sensing element. It measures humidity over the entire range of 0 to 100% RH (non condensing) and has a wide operating temperature range. Its fast response, reliable long-term performance makes this transmitter well suited for refrigeration and HVAC installations.

Johnson Controls® Hx-67x3 Series offers a full line of outdoor relative humidity (RH) transmitters for measuring and transmitting RH levels from 0 to 100%. The RH transmitters provide excellent reliability, long-term stability, and fast accurate response to changes in humidity. Certain models come equipped with a temperature transmitter.

HT-670x Series Humidity Transmitters come in both wall or duct mount packages to meet a variety of sensing application needs. These attractively styled
controllers offer ease of installation and application flexibility. The transmitter generates a jumper-selectable output signal in either the 4 to 20mA or 0 to 10V range, corresponding to 0 to 100% Relative Humidity (RH).

The HT-1000 series room humidity sensors provide active sensing of relative humidity and on specific models, also active/passive sensing of temperature in HVAC applications. It features a polymer capacitance humidity sensing element and provides within either ±2% or ±4% accuracy a voltage output signal proportional 0 to 100% relative humidity.

Johnson Controls offers a complete line of Carbon Dioxide (CO2) transmitters for measuring and transmitting CO2 levels, ranging from 0 to 2,000 parts per million (ppm), within Heating, Ventilating, and Air Conditioning (HVAC) applications.

Johnson Controls offers carbon dioxide (CO2) and temperature transmitters for measuring and transmitting CO2 levels, ranging from 0 to 2,000 parts per million (ppm) and temperatures, ranging from 32 to 122°F (0 to 50°C) within HVAC CO2 and temperature applications.

The Johnson Controls® CD-Px0xx-00-00 Series duct mount transmitters are designed for the measurement of CO2 and temperature in HVAC applications where demand control ventilation (DCV), fresh air and indoor air quality (IAQ), and rooftop air handling economizer control systems are often required.

The F262 Airflow Switch detects airflow or the absence of airflow by responding only to the velocity of air movement within a duct. The single-pole, double-throw (SPDT) control can be wired to open one circuit and close a second circuit for either signaling or interlock purposes.

The DP low differential pressure transmitter series is an accurate and cost competitive solution for measuring low pressures of air and non-aggressive gases in order to monitor and control pressures in building automation, HVAC and clean room systems.

The DPT-2015 Differential Pressure Transmitter senses differential pressure in pressure independent Variable Air Volume (VAV) applications. It sends an analog signal that is proportional to velocity pressure to a VAV controller.

This differential pressure switch is used to sense pressure/air flow in ducts.

Series P74 measures the pressure difference between two sources: supply lines and return lines. A change in differential pressure will reposition the switching mechanism to cause corrective action of the supplementary control equipment.

  TE730 Series Temperature Sensors   Description:
The TE730 Series Temperature Sensors provide temperature sensing in room wall-mount applications. This arrangement allows local temperature setpoint adjustment and temporary occupancy override. A setpoint dial is included on all models to adjust the temperature setpoint.
