Angle position measurement by means of Hall sensors and signal processing including generation of the analogue output signal. Robust brass housing – stainless steel shaft with sliding bearing – sensor circuit consisting of ASIC with Hall elements – electrical connection via connector.

Robust case either in seawater resistant aluminum or in stainless steel - shaft in stainless steel - rotating components with permanent magnet in front chamber - electronic circuit with ASiC and Hall elements and interface components fitted within main chamber, separated from rotating components by a metallic wall - optional potting against water jets (IP 69K) - electrical connections via cable leads with inspection plug.

Robust housing (wall thickness 5 mm) made of seawater resistant aluminium (AlMgSi1) or stainless steel (material: 1.4305 optional 1.4404) - Redundant power supply as well as sensors and electronics - Common shaft (measuring axis) with ball bearing, shaft sealing ring and permanent magnets in prechamber - Sensor circuit consisting of ASICs with Hall elements and interface electronics in closed main chamber - The contactless electromagnetic sensor systems are extended by a 12-bit D/A converter so that the measured variable is available as an analog signal from 0 (4) to 20 mA or 0 to 10 VDC - Electrical connections via connector M12x1.

Robust aluminium or stainless steel housing (wall thicknesses up to 5 mm) - stainless steel shaft and ball bearing - ball bearing with Simmer ring, rotor with shaft and permanent magnet mounted in pre-chamber - sensor circuit consisting of ASIC with Hall elements and interface electronics in enclosed main chamber - housing protection type IP 69K additionally cast - electrical connection via cable (open cable ends).

Recording of the angular position and revolutions by means of Hall sensors - multiturn version with absolute transmission for up to 4096 revolutions - data output plus parameterisation and diagnosis via Profibus-DP. Robust housing manufactured from seawater-proof aluminium or stainless steel - stainless steel shaft - ball bearing with radial shaft seal - sensor circuit consisting of ASIC with Hall elements - electrical connections via the connecting cap with threaded cable connections. The absolute encoders are designed for direct connection to the PROFIBUS-DP. The interface is implemented with the SPC3 Siemens PROFIBUS controller. The protocol corresponds to DP-Slave Class 2 functionality in accordance with Profibus profile for encoders, No. 3.062, and is described in detail in the TRD 12770 user manual. The TRD is mechanicallly and electrically compatible with the electro-optical encoder CRD.

Robust aluminium or stainless steel housing (wall thicknesses up to 5 mm) - stainless steel shaft and ball bearing - ball bearing with Simmer ring, rotor with shaft and permanent magnet mounted in pre-chamber - sensor circuit consisting of ASIC with Hall elements and interface electronics in enclosed main chamber - housing protection type IP 69K additionally cast - electrical connection via cable (open cable ends).

A positive-locking mechanical connection between the cus-tomer’s shaft and the sensor shaft ensures that the magnet in the sensor shaft precisely reflects the rotation of the cus-tomer’s shaft. With the TBN model, one rotation (i.e. max. 16,384 steps) is recorded.With the subsequent absolute transmission, the TRN shaft encoder reaches a measuring range of up to 4096 rotations. The position and speed values (PDO - Process Data Object) are output via the CANopen protocol.

Robust case with wall thickness of 5 mm either in seawater resistant aluminum or in stainless steel - shaft and ball bearings in stainless steel - rotating components with permanent magnet in front chamber - electronic circuit with ASiC and Hall elements and interface components fitted within main chamber, separated from rotating components by a metallic wall - optional potting against water jets (IP 69K) - electrical connections via round plug or lead exit.

The angle transducers have a magnetic scanning according to the HALL principle. Due to the robust design, critical and interference-free applications in harsh environments can be realized. They have a robust housing (wall thickness > 5 mm) made of aluminium or stainless steel, shaft and ball bearing made of stainless steel, shaft with flattening, rotor with shaft and permanent magnet mounted in prechamber, sensor circuit consisting of ASIC with Hall elements and interface electronics housed in closed main chamber. Two models are available: For low and high temperature applications. The model for low-temperature use is equipped with a special grease for bearings and shaft seal. Seals and shaft seal are made of PTFE. Cable gland with clamping jaw pressure screw and silicone seal. The model for high temperature use is without shaft seal. Under the rear cover there is a signal changeover switch (CW/CCW). On the side there is a preset button (4 mA) placed under a screw plug.
