Products/Services for 50 000 Watt FM Transmitters

  • RF Transmitters-Image
    RF Transmitters - (241 companies)
    An RF transmitter is a device that creates a radio signal containing information that with the use of an antenna propagates some distance. The earliest practical RF transmitter was known as a spark gap transmitter which simply generated a spark...
  • Sensor Transmitters-Image
    Sensor Transmitters - (495 companies)
    Sensor transmitters are measurement or signal conditioning packages that provide a standard, calibrated output from a sensor or transducer in the form of a current loop output (e.g., 4-20 mA). Sensor transmitters provide standard, calibrated outputs...
  • Level Transmitters-Image
    Level Transmitters - (304 companies)
    Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. For each measurement, they provide an electrical output that is proportional to the input level...
  • Telemetry Receivers and Telemetry Transmitters-Image
    Telemetry Receivers and Telemetry Transmitters - (365 companies)
    Telemetry receivers and telemetry transmitters are data acquisition components used to gather information from remote locations via wireless communication. Telemetry receivers and telemetry transmitters can be produced as separate receiver...
  • Flow Transmitters-Image
    Flow Transmitters - (235 companies)
    Flow transmitters provide electrical outputs that are proportional to flow inputs. They use flow meters to measure the flow of liquids and gases. Flow transmitters use three basic types of meters: mass, volumetric, and velocity. Meter Technology...
    Gas Transmitters - (112 companies)
    ...or modulated frequency outputs for gas transmitters include amplitude modulation (AM), frequency modulation (FM), sine waves, and pulse trains. Gas transmitters differ in terms of the number of gases sensed, general gas types, and specific gas types...
    Vibration Transmitters - (43 companies) compatible with most meters and data analyzers. Current loop transmitters typically operate over the 4-20 mA or 10-50 mA range. A 4-20 mA loop establishes a 4 mA output as "off" (in this case "no vibration") and 20 mA as "maximum load." When no vibration...
    Pressure Transmitters - (619 companies)
    Pressure transmitters translate the low level output of a sensor or transducer to a higher level signal suitable for transmission to a site where it can be further processed. These devices include pressure sensors, transducers, elements...
    Radio Transmitter ICs - (23 companies)
    ...antenna. There are many different types of radio transmitter ICs. FM devices use frequency modulation (FM), a technique that causes the instantaneous frequency of a sine-wave carrier to depart from the center frequency by an amount proportional...
    pH Transmitters - (50 companies)
    ...pH transmitters provide electrical outputs that are proportional to potential of hydrogen (pH) inputs. How to Select pH Transmitters. pH Transmitter Smart pH Transmitter. Wireless pH Transmitter. Image Credit: Honeywell Image Credit: ECD Image...
