Transducers for Pt-100 and Resistors
General Description
These transducers convert the resistance of a resistive sensor (e.g., Pt-100) to a temperature or resistance dependant linear signal (e.g., 0-10 V or 4-20 mA) or into a frequency output (IR 370, max. 10 kHz). The measurement range and zero-point of the DIL-programmabale transducers are selected by DIL-switches in steps of 10° or 10 Ohm using simple binary codes (10, 20, 40, ...). Various operating modes can also be selected via DIL-switches (2-, 3-, or 4-wire connection, voltage or current output). All settings are calibrated.
Our newest generation of programmable transducers (IR 3XX) allow the setting of almost any desirable range via a RS232-interface. This interface allows also the download of measurement values (AD-converter), calibration date, serial number and more.
- With optional galvanic isolation of input and output, 2- or 3-port isolation, test voltage 1-3 kV.
- Linearization for Pt-100/1000.
- Fixed-range types: Input and output ranges selectable as desired, factory calibrated.
- Programmable types: all ranges and settings can be selected via DIL-switches (depending on module).
- Different housings available.
- Secure against short circuits, connection reversal, up to 30 VDC overvoltage.
- Many options: Different isolaton classes, limit switch, multiplexer, digital interface, frequency output, PWM output.
