A20230 Sensor Transmitter | Input potentiometers and resistors

Description

A20230 Sensor Transmitter | Input potentiometers and resistors

The transmitter for potentiometers for position determination, path measurement or setpoint specification in a 6 mm housing.

  • Universal usability
    with potentiometers, resistive sensors, remote resistance transducers and similar sensors
  • Intuitive configuration
    of basic parameters – easy, without tools, using 4 rotary and 8 DIP switches
  • Calibrated range selection
    without complicated trimming
  • Convenient adjustment
    Start and end points are directly adjusted “at the push of a button“ using the teach-in function
  • Protective separation
    according to EN 61140 – protection of the maintenance staff and downstream devices against excessively high voltages up to 300 V AC/DC
  • High accuracy
    with innovative switching concept
  • Minimum space requirement
    in the enclosure – only 6 mm wide modular housing – more transmitters per meter of mounting rail
  • Low-cost assembly
    quick mounting, convenient connection of power supply via DIN rail bus connectors
  • 5-year warranty

The Task
In many fields of industry the positions of actuators or setpoint devices, for example, must be measured accurately. In many cases they are used as a reference input for controllers or monitoring systems, safety shutdown systems, or for similar critical tasks. As a rule, high demands are placed on function, accuracy, flexibility, and electrical safety. Rotary motion can be measured with potentiometers configured as angle sensors, ranslational motion with linear potentiometers as path sensors. These and other sensors provide a raw signal which is prepared, scaled and converted into a standard signal for further processing using a resistance transmitter.

The Problem
Commercial position sensors have individual characteristics, which requires tedious and time-consuming adjustment of the respective resistance transmitter using  otentiometers. Furthermore, resistance transmitters up to now had a very wide modular housing and therefore occupied a large amount of space in the enclosure. For world-wide applications, several versions with different supply voltages were often used.

The Solution
The universal A20230 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 a “teach-in function“. 3-port isolation with protective separation up to 300 V AC/DC according to EN 61140 ensures optimum protection of personnel and equipment as well as unaltered transmission of measuring signals. The A20230 offer maximum performance in the smallest of spaces. Adjusting the start and end value to the individual position sensor is particularly  convenient using the “teach-in function“ – just at the push of a button on the front of the device. Sensors with known characteristics can be very easily calibrated using four rotary encoder switches and eight DIP switches. Special measuring tasks can be solved with SensoTrans devices which Knick configures according to individual specifications. Fixed-range devices without switch are used, for example, when manipulations or mix-ups must be precluded.

How to get the sensor into the process

Sensors as the direct interface to the process must be exactly matched to the chemistry of the measured medium and to the prevailing pressure and temperature conditions.
