Transmitter telemeter Moduson®3
Ref: 222 094
1. Description
This note describes the functionalities of this transmitter telemeter Moduson®3 and the
compatibilities with the Moduson®3 range.
The transmitter telemeter (ref 222 077) powered by 12V power supply part. 281 612.
The frequency of the transmitter can be adjusted to about 40 kHz.
The transmission of ultrasonic waves is triggered by an On/Off switch.
A reversing switch helps obtain either a continuous transmission or a transmission in
bursts. A second reversing switch helps select the duration of the bursts:
This function is used to measure distances from 0 to 30 cm using the sonar and scan
techniques. Actually, this technique requires that the echo reflected by the object does not
get mixed up with the burst emitted, which requires the use of short bursts.
2. Ideal configuration
The ideal configuration for the measurements is the following:
ENGLISH
•
Long bursts: duration of 6 ms, with a gap of 4 ms between bursts
•
Short bursts: duration of 1 ms, with a gap of 4 ms between bursts
