Transmitter/Sonde Component for Tracking Systems

Product Specifications

Technical details and manufacturing context for Transmitter/Sonde

Definition

A transmitter or sonde is a compact electronic component within a tracking/locating system that generates and emits radio frequency (RF) or other electromagnetic signals. It serves as the active signal source that enables remote detection, position determination, and monitoring of objects, assets, or personnel to which it is attached. The device typically integrates a printed circuit board (PCB) with integrated circuits (ICs), an antenna element, a battery, and a plastic or composite housing. It operates by converting electrical energy from its internal power source into modulated electromagnetic waves at specific frequencies, which are transmitted through the antenna. The signal contains identification data and/or sensor information, which is received by dedicated tracking receivers or base stations to calculate location via methods like signal strength triangulation, time-of-flight measurement, or GPS/GNSS augmentation. Key parameters include operating frequency in the ISM band (315–433 MHz), transmission range of 100–500 meters line-of-sight, output power of 10–20 dBm (subject to regulatory limits), supply voltage of 3.0–3.6 V DC, operating temperature range of -20 to 60 °C, ingress protection rating of IP65–IP67 per IEC 60529, housing material of ABS–PC (flame retardant per UL 94), weight of 50–150 grams including battery, dimensions of 40–80 mm, battery life of 1–3 years at one transmission per minute, positioning accuracy of ±1 to ±5 meters, and modulation types ASK–FSK (selectable). These values are typical reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The transmitter/sonde is a component used in various tracking and locating systems, and its selection depends on required range, accuracy, environmental conditions, and regulatory compliance.

Working Principle

The device operates by converting electrical energy from an internal power source (typically a battery) into modulated electromagnetic waves at specific frequencies. These waves are transmitted through an antenna. The signal contains identification data and/or sensor information, which is received by dedicated tracking receivers or base stations to calculate location via methods like signal strength triangulation, time-of-flight measurement, or GPS/GNSS augmentation.

Frequently Asked Questions

What is the typical operating frequency of this transmitter/sonde?

The typical operating frequency is in the ISM band, ranging from 315 to 433 MHz, depending on regional regulations. Always verify the exact frequency for your application with the manufacturer.

What is the transmission range?

The transmission range is typically 100 to 500 meters under line-of-sight conditions, but actual range depends on the environment, obstacles, and antenna placement. Confirm the range for your specific use case.

What is the ingress protection rating?

The device is rated IP65 to IP67 per IEC 60529, meaning it is dust-tight and protected against water jets or temporary immersion. Verify the exact rating for the model you intend to use.

How long does the battery last?

Battery life is typically 1 to 3 years when transmitting once per minute, but it varies with transmission frequency, output power, and battery capacity. Check the manufacturer's specifications for your expected usage.
