Statox 501 Infratox detects gases in the LEL and ppm range. Protecting people and assets from hydrocarbons The infrared absorption method of gas detection is ideal to detect hydrocarbons such as fuels. It features enough sensitivity to expand the range of application into the ppm range. For instance fuels such as gasoline, diesel or kerosene are mixtures of hydrocarbons. Infrared gas detection theory of operation Some gases absorb light at a certain wavelength (colour). This absorption band is specific to the gas. The rate of the absorption depends not only on the substance to be detected but also on the number of gas molecules (i.e. the concentration of the gas). This premise is used to detect gases. For example, the C - H bond in hydrocarbon molecules will oscillate and absorb light at 3, 4 mm. This fact makes it so easy to detect fuels. Hexane, for instance has 14 C - H bonds compared to Methane which has only 4! A light beam is directed through a cuvette filled with the gas to be detected. The more hydrocarbons are present, the more light will be absorbed. A photo detector at the other end of the cuvette measures the remaining light intensity. The difference between the original and remaining light intensity corresponds to the gas concentration. A reference beam with a different wavelength compensates for potential interferences of dust, humidity or variations of intensity from the light source. Fail-safe technology Failure of important components such as the light source or photo detector will trigger a "system fail" alarm. Most local authorities will accept this as a self-diagnostic feature. Systems including a self-check require less maintenance and calibration, saving time and money. Simple maintenance: Easy to read display and non-Vintrusive calibration The bright LED display of the Statox 501 Infratox shows the gas concentration in percent L.E.L. (Lower Explosion Limit). An important accessory is the calibration adapter, featuring control buttons operating Hall-sensors inside the Ex d housing. The service menu is password protected preventing unauthorised access. All parameters can be checked and changed, or a calibration can be done all without opening the transmitter. The adapter is also equipped with a gas outlet so that it can be used for flow-through applications. Impervious compact design The dimensions of the Statox 501 Infratox are small and compact. The sensor compartment is completely sealed, not allowing dust or insects to enter. It is located in the center of the sensor head. This allows heat radiation from the electronics and the infrared lamp to keep the unit a few degrees above the ambient temperature thus avoiding condensation. This innovative design makes any additional heating unnecessary, allowing the sensor head to be very energy efficient. This saves additional money by eliminating more expensive wiring and a bigger power supply that would otherwise be necessary. The sensor head is rated protection class IP 67 (6 = protection even against fine dust, 7 = submerged 1 m deep in water for 30 minutes). You can have confidence that this system will safely operate even in the harshest environment.

Non-contacting 2-channel flange speed sensor with stainless-steel sensor tube, difference-Hall principle. Due to its design and type approval according to DIN EN 50155 especially suitable for transport technology. Output signals 90° offset for speed and direction of rotation detection (module m1 - m3).

Space-saving, compact – but rugged nonetheless The TRY50 series covers the transition from finger- to hand-size joysticks. This is realized by a construction of the very robust mechanism combined with space-saving Hall sensors. The TRY50 was specifically developed for applications, where a rugged hand joystick is needed, but space is limited. The optimized dimensioning of the mechanism and control lever make it possible to use the joystick in environments, where only finger joysticks would fit, but lack the needed load resistance. The joystick is equipped with Hall sensors and thus shows only minimal drift of the output signal over many years of operation. Optionally, redundant sensors can be chosen to further increase reliability.

High-quality haptics for one-dimensional control tasks The proportional rockers of the PW30 series meet the highest demands on quality and reliability for long-term use in industrial environments. With the look of a rocker switch but the sensor technology of industrial joysticks, the PW30 series combines the advantages of joysticks (for transmitting an analogue control variable) with those of toggle switches (flat design, low space requirement). In addition to two different rocker shapes, choices between potentiometric or Hall-effect sensor technology, as well as between spring return to the centre position or to the end position, are possible. Redundant versions are also available on request.

Unbeatable small installation depth and the highest stability in its class. The joysticks of the series 844 exhibit properties, which are normally found in heavy-duty products only, even though it is a very compact finger joystick. For example, with handle "T" the 844 becomes the most compact stock grip joystick with push button (see picture above in the center). In this configuration, the 844 has the advantage over larger models of lower price and space requirements. The joysticks of the series 844 are equipped with wear-less Hall Effect sensors, are available with up to 3 axes, and exhibit a robust mechanical construction, with a ball-socket pivot. It withstands high push, pull, translational and rotational forces, up to a load of 400 N (vertically). The operational lifetime is up to 10 million operations. With protection up to IP65, a variety of handle shapes, limiters and output options, the optimum product can be selected for the application.
