RPM & Angle Sensors

TAPE SENSOR

The optical tape sensor SE-TAPE-01 is a speed and angle sensor using a black/white tape which is glued on a rotating part. The reflection is converted into a TTL signal, bandwidth 100 kHz. The sensor consists of a tiny electronics part and a 5 m fiber optic cable terminated with a M6 screw. Thus areas where space is very limited still can be reached conveniently.

KEY FACTS

  • Impulse frequency: max. 100 000 pulses/s
  • Temperature range: -10 °C to +50 °C
  • Working area: 1 to 5 mm

TACHO-PROBE-01 & TACHO-PROBE-02

Both sensors are emitting light which is reflected from an object and received by a photo transistor. The output of this sensor is an analog voltage signal.

Connected to an analog input of any DEWETRON system, the RPM and angle information are extracted in the software. You can see the shape of the curve, and can define the trigger level in the prepared angle mathematic of the software.

KEY FACTS

  • Impulse frequency: 10 to 15 000 pulses/s
  • Temperature range: -10 °C to +60 °C
  • Working area: 1 to 2 cm

 

DIFFERENCES BETWEEN
-01 & -02

The difference between Tacho-Probe-01 and -02 are the plugs on the 5 m cables: DB-9 plug on probe-01 and BNC and Lemo plug on probe-02.

DEWE-RIE ENCODER

The DEWE-RIE (Rugged Industrial Encoder) works based on transmission light principle which avoids attrition and malfunction.

The very rugged encoder is mounted between engine and brake shaft. An infrared beam is emitted and received at the sensor unit. The customized marker disk (with slits) is mounted in-between the sensors gate. The slits will interrupt the infrared beam, the receiver transforms the light to voltage.

DEWE-RIE offers TTL signal output and can be connected directly to anycombustion analyzer or torsional and rotational vibration analysis system from DEWETRON.
