D^X Telemetry: modular, multi-channel telemetry system for a variety of applications

A highlight of CAEMAX´s new, fully digital D^X telemetry is the ability to perform an absolutely synchronous data acquisition with several transmitters in one single ISM band. With one single telemetry transmitter up to six channels – e.g. two strain gauge full bridges or four half bridges or analogue signals or temperatures can be transmitted. The max. sum sampling rate is 7,2 kHz.

Clearly structured menus provide easy handling even for the unexperienced user. The system supports either manual configuration at the receiver console or remote control by an integrated web browser.

A variety of solutions is available for the power supply of the transmitter: Inductive head or ring stator for continuous operation as well as accu packages or various battery solutions which allow a secure power supply over hours or even days.

The D^X telemetry system has been widely approved for drive shaft torque measurements in drive tests. For this application, CAEMAX offers convenient half-shell housings for quick and easy mounting. The housing not only protects the strain gauge application, but additionally contains the telemetry electronics as well as the secondary coil for inductive supply.

Based on this system, CAEMAX has developed an innovative complete solution for power acquisition from rotating parts: In addition to torque, the revolutional speed of the shaft is acquired. The rotational power of the drive shaft is calculated online from these two measurement channels. As the sensors for rpm acquisition are completely integrated to the shaft housing, this very robust system works completely without accident-sensitive stator head for rotational angle acquisition. This project was supported by the Federal Ministry for Economic Affairs and Energy.

CANbox: Easy CAN-Data Transmission via WLAN

By means of the CANbox, measurement data can be sent or received from one or two CAN interfaces, buffered and forwarded wireless via WLAN – e.g. to the WLAN client on your notebook. In case of transmission failures due to bad environmental conditions up to 32 MByte RAM are provided as a storage buffer. As all CAN messages will be marked by a time stamp the correct sequence in time is completely secured.

Tentaclion: Fast Data Transmission for Mobile Outdoor Applications

Tentaclion is a smart and fast modular measuring system which supports all common sensor types and provides a signal bandwidth of up to 20 kHz per channel. The Ethernet interface provides easy and direct connection to any PC or notebook. The especially rugged and weatherproof system, suitable for outdoor applications, also allows wireless data transmission over distances of up to 3 km (line-of-sight).

J1 One-Channel Telemetry System

The one-channel telemetry system J1 is designed for measuring torques, temperatures or pressures from rotating devices with high long-term stability. As the J1 is easy to mount and versatile in use and power supply (battery or inductive supply), it is a good choice for a variety of rotating devices. For minimal installation debth, the rotor unit can also be realized as an ultra-flat, flexible board.
