The GMT220 transmitter series is designed for a wide range of industrial carbon dioxide applications including greenhouses, fruit storages, safety alerts and demand-controlled ventilation in mushroom farms, livestock husbandry and parking garages.
The GMT220 transmitters measure carbon dioxide in harsh and humid environments. The housing is dust and waterproof to IP65/NEMA4. The materials have been chosen for extended corrosion resistance.
The GMT220 transmitters are easy to use and install. The transmitters have a modular structure which includes a separate mounting plate for easy installation.
Interchangeable probes facilitate field maintenance. The probes can simply be replaced with newly calibrated ones, or with separate probes that are only used as a reference for calibration checking. This minimizes downtime and eliminates the need for expensive calibration equipment.

Besides pH and dissolved oxygen measurements, reliable monitoring and control of the CO2 partial pressure is important for successful fermentation. The oxidation of carbohydrates to CO2 water results from aerobic respiration. METTLER TOLEDO's new CO2 measuring system is specially designed for in-situ measurement into a bioreactor and therefore "registrates" exactly the same partial pressure as the cell.
METTLER TOLEDO offers a wide range of different measurement systems for very specific requirements in different industries consisting of sensors, housings, transmitters, services and fulfills all high quality requirements.

The gas measuring systems for explosive gases and vapors made by J. Dittrich Elektronic determine the concentration of explosive gases and vapors in air in an ambient temperature from -10 to +50° C.
A pellistor or semiconductor sensor detects methane (CH4), hydrogen (H2), propane (C3H8), alcohol and benzine; additional hydrocarbons on request.
The calibration is carried out with the aid of the respective test gas by means of a potentiometer; however, a certain amount of cross-sensitivity of the sensor with regard to the other substances always remains.
Low-cost infrared measuring system for methane
Since the cross-sensitivity of the sensors gives rise to problems when monitoring methane, J. Dittrich Elektronic developed a new infrared measuring system which detects specifically methane quicker, more accurately and at less cost than conventional infrared systems.

The capcitive filling level systems operate according to the three-electrode principle. With this principle the container or an additional electrode serve as a counter-electrode to the probe electrodes. For this reason it is necessary with this system that the container is of a conductive material or a "substitute electrode" is fixed to the container wall, e.g. copper foil. These systems are available with probes for analogue filling level measurement of for detection of 1, 2 or 3 measuring points. The position of the switching points and the analogue measuring area is user-definable within the possible effective range and therefore it can be determined for optimal matching of each application. Level measurements of bulk material, liquids or pastes are possible with a dielectric constant as of år 1,1.

EASYROLL transmitters are equipped with the E.R.P.A. function (which allows a valid copy remote to be inserted in place of a lost or stolen unit).
E.R.P.A. is the third evolution of PRASTEL’s Rolling code technology, allowing the insertion and simultaneous cancellation of a lost transmitter. In existing installations this easy to function to perform,simply pressing the transmit button on the copy remote (within 4-5 m of the receiver) enters the new remote into the system memory and removes the old transmitter. Once this simple operation has been performed, the new transmitter will be ready for use.

The Wi.M868T-R™ 868-870MHz transmitter module is a microcontroller-less version of our popular Wi.232DTS-R™ and Wi.232FHSS-25-R™ modules. It offers the same excellent RF performance, yet allows the design engineer to control the radio at the physical level using any microcontroller.
The module is footprint compatible with the many of the Wi.232 family of radios, including the 900MHz Wi.232DTS-R, Wi.232FHSS-25-R, Wi.M900X-R, and the European 868MHz Wi.232EUR-R, and Wi.M868X-R. The Wi.M868T-R supports wide-band mode, where the channel width is 600kHz and also a narrow-band mode where the channel width is 200kHz.The module is configured via a simple SPI style serial interface. Data is transmitted and received using a separate digital serial interface that includes pre-amble and start-of-packet detection.
Maximum transmit power is +15dBm. Maximum receive sensitivity is -112dBm. The transmitter draws 62mA typical at +15dBm. The module has 32 wideband and 84 narrowband channels available.
A footprint compatible module companion version is available in 902-928 MHz for the North American market Wi.M900T-R.
A typical circuit consists of a low-cost microcontroller, a power source, a Wi.M868T-R module, and an antenna. The RK-Wi.M868X development kit is available to support evaluation of this product with separate Wi.M868X-EVM-R evaluation modules for additional wireless node development. The Wi.M868X-R is very similar to the Wi.M868T-R except the Wi.M868T-R is configured as a uni-directional transmitter only device where the Wi.M868X-R is a bi-directional transceiver module. For production, order the Wi.M868T-R.
