Converting voltage, current, frequency and power
Transducers convert a signal in one form of energy into a signal in another.
Transducers are often automation, measurement, and control systems, where electrical signals are converted to another.
Thiim A/S can supply transducers in the array: voltage, current, frequency and power.
Current transducers
The transducers type IAMA for current are developed to meet high demands for quality and by offering 8 selectable outputs it covers a broad range of applications
IAMB and UAMB are reduced versions with 4 to 20mA output only. The input current or voltage is, by means of a high-grade transformer (class. 0.2) with an isolation voltage of more than 4kV, galvanic isolated from the transducer circuitry and the output. After the transformer the measured signal is rectified, averaged and corresponding to the DIP-switch settings, converted to the required current or voltage output signal.
For PLC, PC and micro processor controlled instrumentation.

Frequency transducers
The transducer type FAMA is used to measure the frequency of an input voltage. The output is a load independent DC voltage or current signal. The input can be connected directly or via transformers.
The input voltage is transformed to a suitable signal level. At each zero-crossing the input creates a rectangular pulse with a constant height and width. The pulse train, with a frequency proportional to that of the input voltage, is filtered and in amplifier converted to a load independent DC output. The input voltage can also be used as supply voltage. The supply voltage is galvanically separated by the plug-in transformer.
For instrumentation, PLCs, PC and microprocessor control systems .
Power active or reactive transducers
The input transformers for voltage and current separate the inputs galvanically from the converter. The signals are amplified to suitable levels and led to the multiplier.

The signal from the multiplier passes an active filter and an output circuit to ensure a low ripple and stable output signal. Output signals are short-circuit and open-circuit protected.
