Environmental Sensor Has Wide Variety Of Indoor Applications

Carlo Gavazzi Automation, the international electronics Group with activities in designing, manufacturing and marketing of electronic equipment, launches the CGES Series, a new range of sensors designed to measure various indoor environmental parameters, including CO2, Humidity, Temperature and Air Velocity.

When CO2 levels rise to an unacceptable level, with poor air quality and stuffy rooms, the CGES sensors can be used to help increase the supply of fresh air into the building and, as a result, improve the indoor air quality. The CGES sensors can be a significant contributor to compliance with ASHRAE 62-1989, which recommends a maximum concentration of 1,000 ppm of CO2 indoors. Additionally, the auto-calibrating feature ensures that the CGES is properly tuned for continuous, worry-free operation.

The CGES Series can also be used to control humidity levels in wet climates, thus elevating the comfort level of the occupants and discouraging the growth of mildew. Air velocity and temperature sensors can be used to keep indoor air temperatures at comfortable levels, and maximize energy efficiency.

All of these new sensors operate on 24 VAC/DC for flexibility, and feature multiple output options, including 0-10V, 4-20mA, and switching. They can be mounted in walls or ducts. The CGES sensors are a complete and versatile solution with applications in office buildings, schools, pools, museums, green houses, incubators, and food storage rooms, among many others.

Long Range Diffuse Photoelectric Sensor

Buffalo Grove, IL – Carlo Gavazzi launches a new long range diffuse photoelectric sensor with background suppression technology. The new PD112 will detect black objects at distances up to 2 meters, and white and grey objects at up to 2.5 meters. Using triangulation technology, the PD112 can be easily and precisely adjusted, with a 28 turn potentiometer. The user can fine tune the sensor to detect the target at the desired distance, while completely ignoring reflective objects only millimeters beyond.

The PD112 is packed with features that make it simple to use, and highly versatile. Each model has both NPN and PNP output, which is automatically detected by the sensor when wired. Normally open or normally closed output can be selected via a dip switch. Two adjustable timers (1 – 16 seconds) for ON and OFF delay allow for a customized solution.

A truly innovative feature of the PD112 is the mode operation selection. The sensor can be operated in a traditional industrial mode, which is ideal for applications such as material handling, packaging and wrapping, and wood processing. By making a simple dip switch selection, the PD112 can also be operated in a door mode, which automatically optimizes the performance of the sensor for detecting people and objects around automatic doors. This mode allows the sensor to be remotely tested by a door controller, making the sensor compliant with door industry safety standards.

Miniature Photoelectric Sensors

Buffalo Grove, IL – Carlo Gavazzi has launched the next generation of state-of-the-art miniature photoelectric sensors with exceptional features. Housed in a world standard style, these sensors are well-prepared for global applications.

The new PD30 Series sensors feature simple to use, precise push button programming, eliminating the trial and error setup required with potentiometer based sensors. Many of the models also allow remote teaching options, so setup and programming of the sensor can be done away from the application. These same models also provide an option for locking the sensor settings, giving a tamper-resistant set up that allows for more secure operation. A muting version provides various benefits, including mutual interference protection, sensor alignment aid, and the ability to verify the sensor’s proper operation remotely, via a PLC. A dust alarm output signals an alarm when the sensor lens needs to be cleaned, reducing downtime and improving sensor performance.

The PD30 Series is available in six sensing technologies, several with advanced ranges previously unheard of in sensors this size, including through beam (15m) and polarized retroreflective (6m). Diffuse reflective, background suppression, retroreflective, and a transparent object detection model are also available. Each sensor is powered by 10-30VDC, and have a 100 mA transistor output, which can be programmed as normally open or normally closed. The sensors are constructed in compact 10.8 x 20 x 30mm housings, and prices start at just $70.

Mini Photoelectric Sensors

Buffalo Grove, IL – Carlo Gavazzi has launched a new series of compact, versatile photoelectric sensors, offering exceptional features and outstanding value.

The new CGPS Series sensors feature a universal housing style which can be installed via the threaded M18 barrel, or secured with screws to a bracket via the mounting holes on the flat sides. All of the sensors have both normally open and normally closed outputs, so the right output choice is always available. The sensors also feature a dual LED indication, and many models offer sensitivity adjustment via a potentiometer, therefore set up is simple and fast. Connection options are plentiful as each model is available with your choice of a hard-wired cable, a M8 quick-disconnect plug, or a ‘pig-tail’ option which combines both cable and M8 quick disconnect plug.

The CGPS Series is available in three sensing technologies, each with exceptional sensing ranges. Diffuse reflective in 100 and 300 mm ranges, retro-reflective with a 6 meter range (including a 3 meter polarized option), and through-beam models in 6 and 20 meter ranges are offered. All sensors are supplied by 10-30VDC, are compact in size, merely 13.5 x 29 x 35mm, and come with 150mA complementary transistor outputs. Prices start at just $43.

All of the CGPS Series sensors carry UL and CE approvals.
