Resistance Transmitter

SensoTrans R P 32300

The universal SensoTrans R P 32300 resistance transmitters provide connection possibilities for all standard potentiometers for angle, path or position detection up to 50 kohms. They can be flexibly adapted to the respective measuring task using DIP and rotary encoder switches or via an IrDA® port.


  • Universal usability with potentiometers, resistive sensors, remote resistance transducers, and similar sensors
  • Convenient setting of all parameters via IrDA port
    • Uncomplicated, menu-guided adjustment also "on site"
      including archiving of the configuration data
  • Intuitive configuration of basic parameters
    • Easy, without tools, using 4 rotary and 8 DIP switches
  • Calibrated range selection
    • No complicated trimming
  • Convenient adjustment
    • Zero point and sensitivity adjustable via IrDA port
  • Simulation of any desired output values for correct installation/commissioning
  • World-wide usability due to 110 V AC to 230 V AC broad-range power supply
  • Protective separation according to EN 61140 - protection of the maintenance staff and subsequent devices against excessively high voltages up to 300 V AC/DC
  • Functional safety up to SIL 2 (up to SIL 3 in case of redundant configuration) with TÜV certificate
    • Systematically developed according to EN 61508
  • High accuracy due to innovative circuit design
  • Minimum space consumption in the enclosure
    • Only 6 mm wide modular housing
    • More transmitters per meter of mounting rail
  • Low-cost assembly
    • Quick mounting, convenient connection of the power supply through DIN rail bus connectors
      (in case of 24 V DC power supply)

3-port isolation with protective separation up to 300 V AC/DC according to EN 61140 ensures optimal protection of personnel and equipment as well as unaltered transmission of the measurement signals.

The SensoTrans R P 32300 offer maximum performance in the smallest of spaces. Adjusting the start and end value to the individual position sensor is particularly convenient via the infrared interface, for example using a PDA. Sensors with known characteristics can be very easily calibrated using 4 rotary encoder switches and 8 DIP switches.

Special measuring tasks can be solved with SensoTrans devices that Knick configures according to individual specifications. Fixed-range devices without switches are used, for example, when manipulations or mix-ups must be precluded.

Knick offers the SensoTrans R P 32300 transmitter with SIL approval for applications with high demands on functional safety. The requirements of EN 61508 were implemented through specially developed hardware and software. The implemented fail-safe concept makes use of structural measures at the device level (redundancy of system components) and diagnostic methods for selective fault detection. The product is SIL 2 approved (EN 61508) by an authorized body (TÜV Rheinland). SIL 3 in redundant implementations.
