Environmental transmitters are without question one of the most important parts of any control setup. Transmitters are designed to be the interface or method used to control various applications and instruments. By nature, environmental transmitters vary in complexity, as well as access method of control, portability, and features.

Learning from the Best

An excellent way to learn about different environmental transmitters is to look at what one of the world’s leaders has to offer. Comptus produces the highest-quality sensors, controls, and transmitters for a wide range of applications. Used for agricultural, educational, governmental, recreational, and energy purposes, this is the company to turn to.

  • Wind Speed and Direction – Specific to wind, environmental transmitters such as the Comptus A70-S and A70-D have the ability to convert sensor signals into electrical outputs that are completely suitable for connection with computers, displays, wireless transmitters, data loggers, building automation systems (BAS) wind alarms and various other controls. In addition to there being a wide range of options for output, these transmitters come standard in a track mount for existing enclosures and are also available in NEMA-rated enclosures.
  • Barometric Pressure – These environmental transmitters come in outputs of 0-1 mA, 0-1V, and 4-20 mA. Regardless, all systems can be powered using 12/24 VDC, 24 VAC, 120 VAC, or 230 VAC. The transmitters also come in several distinct packages that include NEMA 12 enclosures that offer outstanding protection from dust when used indoors. For both indoor and outdoor use, the NEMA 4X enclosure is ideal with protection from blown dust, corrosion, ice, and rain.
  • Solar Radiation – For these environmental transmitters, there is a choice of two models: the Comptus A70-A PAR Sensor, which measures photosynthetically active radiation within the 400 to 700 nm range (light visible to the human eye), and the Comptus A70-I Insolation Sensor, designed to measure solar radiation in the 280 to 2800 nm range. Both the sensors and transmitters offer an analog signal output that is proportional to the phenomenon being monitored. All components are rugged, reliable, and guaranteed to provide years of seamless service.
  • Rain – Comptus also has an environmental transmitter for rain. The signal from the rainfall tipping bucket is converted into a 4-20 mA signal that goes to outputs like computers, data loggers, building automation systems (BAS), meters, and others.
  • Air Temperature and Humidity – Known as the A70-T, this environmental transmitter produces analog signals that are proportional to both the air temperature and humidity. This system offers several options for output, and instructions are available in a number of unique packages. Various options for NEMA enclosures provide protection from rain, ice, blowing dust, and corrosion.
