September 2017

The CASSY sensor range got extended by a new voltage sensor S.

More than 50 sensors for over 100 variables are offered within the CASSY sensor portfolio. The new µV sensor S is especially designed for measuring very low voltages (e.g. Hall voltages, thermocouples, induction coils) using CASSY. 

It can be used in combination with Sensor-CASSY 2, Mobile-CASSY 2, Pocket-CASSY 2 and the Universal Measuring Instrument.

Renewed approval for the LEYBOLD X-ray apparatus according to the Röntgenverordnung 2017 (X-ray Ordinance 2017) until 2027

../../fileadmin/user upload/LD Didactic/Bilder/Neuheiten/Neuheiten 2017/LEYBOLD Roentgengeraet Mo komplett 554801

May 2017

Safety requirements 2017 satisfied:
The BfS (Federal Office for Radiation Protection) has extended the design approval for the LEYBOLD X-ray apparatus as X-ray apparatus for educational use with full protection in accordance with the regulation BfS 05/07 V/Sch RöV.

After presenting the LEYBOLD X-ray apparatus in accordance with the specifications of the current Röntgenverordnung (X-ray Ordinance) and the regulations concerning an X-ray apparatus for educational use by the PTB (Physical-Technical Federal Agency), we are delighted to confirm that the BfS (Federal Office for Radiation Protection) has extended its approval.
The LEYBOLD X-ray apparatus you will be purchasing for educational use is fully protected with the required safety features, consequently the equipment has been certified by the authority as reliable, conforming to the appropriate standards and can be regarded as “state-of-the-art”.

Safety and radiation protection as top priority

In addition to the fulfillment of the dose rate limits according to the Röntgenverordnung (X-ray Ordinance), an automatic door monitoring system prevents improper operation of the doors. For this purpose, the doors are automatically locked and monitored by two independent safety circuits. Before switching on the high voltage, the functionality of the safety circuits is independently checked by the apparatus. If the doors are not locked properly, no high voltage and hence no X-ray radiation will be generated. The display then shows the probable error (for example, door open). The safety system for the doors also ensures that the doors are not unlocked until the high voltage has dropped and until no more X-ray radiation is being generated. The automatic safe locking and unlocking of the doors has been successfully tested by TÜV Rheinland (a German Technical Inspection Association) for reliability and failure safety.

Further advantages of the proven X-ray apparatus

The LEYBOLD X-ray apparatus impresses not just with its superior and currently tested safety concept, but also with its continuously improved capabilities and features during the years. Six different X-ray tubes (with different anode materials) are available, which is a unique feature for an educational X-ray apparatus. The X-ray tubes are, depending on their application, characterised by high intensity X-ray radiation (Au tube) or of a suitable wavelength for crystallographic experiments (Cu tube). The simple tube change allows a direct and didactically valuable view of the X-ray tube. With an angle resolution of 0.01° and appropriate accessories (high-resolution collimator, counter tube holder and adapted software), the X-ray apparatus sets new, much higher standards. This astonishing precision in the field of education enables Bragg-HD measurements where the effects of the fine structure are visible in the first order and can be observed with a correspondingly high count rate. The storage of the materials is improved by an additional, lockable drawer which provides optimal space for a high number of accessories such as X-ray tubes, absorbers and counter tubes, and leads to a further simplification of its handling and operation.

WiFi adapter for Sensor-CASSY

../../fileadmin/user upload/LD Didactic/Bilder/Produkte Loesungen/CASSY/Sensor-CASSY 2 WLAN 524013W

January 2017

With the WiFi adapter it is now possible to easily connect the Sensor-CASSY and Sensor-CASSY 2 to a computer or tablet without any cables.

With the WiFi adapter, the Sensor-CASSY 1 (USB or RS232) as well as the Sensor-CASSY 2 wirelessly connects to a computer or tablet in the WLAN network. Or even spans a WLAN network (access point).

Therefore the WiFi adapter is easily plugged in to the Sensor-CASSY. After that the Sensor-CASSY can be connected to an existing WLAN as a WLAN client. Or the adapter can set up its own wireless local area network (WLAN) or as you might know from your smartphones a so-called access point. A computer or tablet can be directly connected to this WLAN.

After all devices are in the WLAN, the Sensor-CASSY can connect to CASSY Lab 2 and the NEW CASSY app.

This opens up new possibilities:

  • Wireless connection to CASSY Lab 2 under Windows / Linux, e.g. to the computer on the whiteboard.
  • Wireless connection to one of our apps (multimeter, oscilloscope or the CASSY app) on tablets or smartphones.
