A variety of Current Transducers and RPM & Angle Sensors
DEWETRON offers several solutions for current measurement from simple shunts to current clamps and high-precision zero flux transducers. There are versions for pure AC current which do not need any power supply and versions for DC and AC current which can be supplied from the DEWETRON instrument. Have a look at the tables below.
You are looking for an RPM or angle sensor to complete your DAQ system for your demanding measurement task? Then have a look at our Tape Sensor and Tacho Probe below.

DW2-CLAMP-DC-POWER-8
You need to connect more current transducers to a DEWE3-a4 or a DEWE3-M4? Then use the DW2-CLAMP-DC-POWER-8 box for connecting up to eight current clamps to a DEWE3-A4/DEWE3-M4/DEWE2 system.
The box comes with an integrated power supply for up to eight current clamps (±15 V / +9 V), as well as a power supply connector for the instrument (11 to 32 VDC).

RPM & Angle Sensors
Tape Sensor
- Optical tape sensor SE-TAPE-01 is a speed and angle sensor that uses black/white tape attached to a rotating part. The reflection is converted into a TTL signal with a bandwidth of 100 kHz.
- Impulse frequency: max. 100 000 pulses/s
Tacho Probes
- These sensors are rpm and angle sensors, where the sensor emits light which is reflected by an object and received by a phototransistor. The rpm and angle information is processed by the software. The output of this sensor is an analog voltage signal.
- Impulse frequency: 10 to 15 000 pulses/s
- 2 types available: DB-9 connector (PROBE-01) or BNC and Lemo connector (PROBE-02)
