Steering effort sensor - The new KMT-CLS measurement steering wheels sensor is designed for applications in any car or commercial vehicle steering system. The KMT-CLS sensor is available with a torque range of ±100Nm and ±200Nm, the range for the steering angle is ±1340°. At the CAN output in addition the rotational steering velocity (±1000°/s) is available. The control unit provides a free configurable CANoutput simultaneously for the data transmission of all values and two analog outputs for steering angle and torque. In addition torque and angle can be metered on two displays of the control unit. The zero balance of steering angle and torque is also initiated at the control unit. All features of multi-function steering wheels can be maintained because no change is necessary on the original steering wheel. Up to six electrical signals can be connected through the KMT-CLS.

R16-PCM telemetry system SET
|
The new
R16-PCM-Rotate is a rugged, waterproof axial unit for collecting
dynamic measurements from rotating devices under shock and vibration
loads like railway wheels, gear boxes, test rigs or other axial
applications. It enables conditioning, digitization and wireless
transmission of up to 16 parallel strain gage (STG) signals. Signal and
power transfer is contactless, data being transmitted optically and
power inductively. No batteries and no routine maintenance! The fully
sealed environmental housing and extended operating temperature range
make it particularly suitable for off-road and winter testing in
arduous conditions.
On the
rotating side the strain gage signals are conditioned and amplified.
The analog strain gage signals are converted into a 16 bit digital
format. Data transmission from the rotating to the stationary side is
achieved by an infrared telemetry link along the centerline of the axis
for a serial bit stream. The power for the rotating amplifiers sensor
excitation and signal conditioning is supplied via induction. This
ensures uninterrupted continuous power supply. The rotating strain gage
amplifiers are software programmable via web interface. The settings
are gain, auto-zero and type of strain gauge.
On the
stationary side the digital output is connected to the decoder unit via
a standard data cable. The decoder unit converts and de-multiplexes the
serial bit stream into a parallel format. This parallel signal along
with address and clock information is converted to 16 each analog
signals (+/-10V) and made available on a Sub-D connector on the decoder
unit. Optional is an IP-LAN interface for digital transfer of
data’s into the PC available.

General Description
The TEL1-PCM single-channel telemetry system offers the easiest handling for the wireless transmission of strain gage signals from rotating shafts. The very small encoder 35 x 18 x 12 mm with a weight of 13g. The transmitter (encoder) part is simply mounted on the rotating shaft with a special fiber reinforced tape. Powering of the transmission part and the digital data transfer between transmitter and receiver is realized inductively.
Functional Description
The TEL1-PCM transmitter provides a pulse code modulated signal (PCM) to an induction winding around the shaft (max. diameter 500mm, other on request!). The magnetic field of this winding enables the inductive transmission of the signal to the pickup coil. From there the signal is transferred by cable (5 m) to the receiver. The maximum distance between the transmitter coil and the pickup is 25mm. (with standard head)
The receiver unit offers a BNC connector at the front panel with analog outputs ± 10 V and a optional a digital output for PCM interface ECIA100 (for notebooks) or IF16 (PCI Desktop). An LED bar indicator shows the actual level and a successful Auto Zero calibration. Overload is indicated by the last LED´s in pos. or neg. direction of the bar graph. These OVL-LED´s operate in peak-hold mode and are reset by pressing the overload switch.
Strain gage sensors (>350 Ohm) in full- and half- bridge configuration can be directly connected to the transmitter. The excitation is fixed to 4 Volt DC and the gain is set by the gain switch on the receiver side. An auto-zero (AZ) adjustment is executed by pressing the AZ button on the front side of the receiver. The successful AZ operation is indicated by a yellow LED in the middle of the LED bar indicator. When the AZ completes the LED continuously illuminates. A continued flashing of the yellow LED indicates some error in the AZ electronics. In this case please contact the support of KMT. Additional to the AZ you have the possibility to calibrate the bridge by external shunt. (+ and -). The AZ setting is stored in a Flash-RAM and thus is not lost during power-off. Use only shielded sensor cable.

CT2-Wheel is an telemetry system designed for easy mounting onto rotating Wheels to provide non-contact transmission of measured parameters such as pressure, force, temperature, acceleration and voltage.
Sensors inputs are connected via screw on, waterproof connectors. Measured values are prepared in analog format, digitized and transmitted via radio frequencies. Four different carrier frequencies are provided, this allows up to four systems (e.g. for four wheels) to operate in parallel. The complete transmitter assembly is waterproofed to IP65 specifications.
The following sensors can be connected to the system: (STG) Strain gages sensors in full-, half- and quarter-bridge configuration (350 ohm or greater), Type K Thermocouples to 1000°C, ICP and capacitive sensors. Voltage inputs of +/-5V and +/-10V are available.
The measured values are processed and output as +/-5V analog signals at the BNC sockets (optional digital output for special PCM interface into a PC) on the stationary receiver located in a vehicle or helicopter cabin.
Resolution of 12 bits is standard; this enables an amplitude dynamic of 72 dB. The analog signal bandwidth is 0-375 Hz (-3dB). The measurement accuracy is +/-0.25 % (without sensor). The CT2-Wheel is suited for operation at ambient temperatures of -20 to +70°C. The transmission distance between transmitter and receiving antenna is of the order of 10m (30 feet) - depend of application!
