Measuring transducer for level- and temperature sensors
A measuring transducer, also referred to as a signal converter or transmitter, is a device or apparatus used in metrology to convert or transmit a specific measurement signal into another signal. This is done to process and transmit measurement values from a sensor or measuring device in a manner suitable for subsequent processing, display, or control.
Functions
The primary function of a measuring transducer is to convert the measurement signal into a standardized output signal that can be easily interpreted and further processed by other devices. Typically, the output signal of a measuring transducer is provided as electrical voltage, current, or digital signal.
Examples
An example of a measuring transducer is a temperature transmitter, which converts the measurement signal from a temperature sensor (such as a thermocouple or resistance thermometer) into a standardized 4-20 mA current signal, compatible with many process control systems. Another typical measuring transducer is a level transmitter, which converts the level measurement from a sensor into a 0-10 V voltage, which can then be read by a digital display device or other control unit.
Industries and Applications
Measuring transducers are widely used in various fields, including industrial automation, process control, control engineering, monitoring systems, and laboratory metrology. They play a crucial role in capturing and transmitting measurement data, contributing to the improvement of efficiency, safety, and accuracy in measurement processes.
