Technical details and manufacturing context for Signal Converter

Definition
A signal converter is an essential component in flow meter/sensor systems that transforms the raw output signal from the flow sensor (such as analog current, voltage, or frequency) into a standardized, processable format compatible with control systems, data loggers, or display units. It ensures accurate signal transmission and interface compatibility. The converter typically accepts standard analog inputs like 4–20 mA or 0–10 V, as well as pulse frequency signals, and conditions them through amplification, filtering, or isolation circuits. The output can be a different analog range or a digital protocol such as RS-485 or Ethernet, depending on configuration. Key parameters include input and output signal types, accuracy of ±0.1% of span, supply voltage of 24 V DC ±10% with reverse polarity protection, operating temperature range of -40 to 85 °C, and storage temperature of -40 to 100 °C. The device offers ingress protection ratings from IP65 to IP67, response time ≤100 ms for step input, load resistance up to 600 Ω for current output, and isolation voltage of 1500 V AC between input and output. The enclosure is typically made of stainless steel 316L, and the weight ranges from 0.5 to 1.5 kg depending on housing. These specifications are reference values and must be verified for the specific model and application. The converter is designed to meet various IEC standards, including IEC 60381 for analog signals, IEC 60770 for accuracy and response time, IEC 61131-2 for supply voltage, IEC 60721-3-1 for environmental conditions, IEC 60529 for ingress protection, and IEC 61010 for isolation. Always confirm model-specific values and standards with the legal manufacturer or supplier before procurement.
Working Principle
The signal converter receives an input signal from the flow sensor (e.g., 4-20mA, 0-10V, pulse frequency), conditions it through amplification, filtering, or isolation circuits, and outputs a converted signal (e.g., to RS-485, Ethernet, or a different analog range) according to preset scaling and configuration parameters. The input stage may include protection against reverse polarity and overvoltage. The conditioning stage ensures signal integrity by removing noise and adjusting levels. The output stage drives the connected load within specified limits. The converter's configuration parameters, such as scaling and output type, are set via DIP switches, software, or other means, allowing adaptation to various control systems.
