| KMT-CLS Measurement Steering Wheel Sensor NEW!! |
|
|
|
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.

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! |

RPM and SPEED measurement in cars via CAN “On-Board Diagnostics” interface with analog and pulse outputs. RPM-8000-OBD2 offers a discerning solution for automotive RPM measurement without an additional sensor. The information will read direct from the CAN-OBD2- interface (DIN 15765, J1939-7). The instrument is simply connected to the standard OBD2 connector and the RPM or SPEED is shown directly on the LCD display. You even have the choice to output the data as an analog voltage (0-5V) or as a digital pulse sequence (TTL).

The RPM measuring range of the analog
output is 0.5 Volt per 1000 RPM. The standard TTL frequency output of 30Hz
per engine revolution can scaled with a frequency divider of 1:1, 1:2,
1:4, 1:8 or 1:16. The SPEED measuring range of the analog output is 0.020V
per km/h (0-5V = 0-250km/h) The TTL frequency output is 16Hz/km/h max.
250km/h.
