What is a sonde instrument?
Sondes are small, lightweight and compact balloon borne instruments, developed for measuring the vertical distribution of atmospheric ozone, aerosols and water vapor in situ up to an altitude of about 30-35 km.
What is the purpose of Sonde?
Used to locate buried plastic Water Pipes, Gas Pipes and any other non-magnetic utility, Sondes are self-contained transmitters that are used with our cable and pipe locators. Sondes are typically attached to a Flexrod, pushed along the pipe, and the position of the Sonde detected from above ground.
What is Sonde frequency?
Frequency. 512 Hz. Size (inches) 1.53″ dia x 4.13″ Battery.
What is sonde in geophysics?
1. n. [Formation Evaluation] The section of a logging tool that contains the measurement sensors, as distinct from the cartridge, which contains the electronics and power supplies.
How accurate is a sonde?
Theoretical advertised accuracy of sonde/receivers is 2.5 to 5% with sondes that are larger and higher strength than those that can be robotically launched with CCTV equipment.
What is sonde in drilling?
A sonde transmitter (probe) is a an electronic device that fits inside the drill head housing and transmits a magnetic field to your Ditch Witch locator or DigiTrak locator. In horizontal directional drilling, sondes are used to pinpoint exact location of the drill head during a pilot hole process.
What is geophysical survey of borehole?
Borehole geophysics is the science of recording and analyzing measurements of physical properties made in wells or test holes. Probes that measure different properties are lowered into the borehole to collect continuous or point data that is graphically displayed as a geophysical log.
What is a multiparameter sonde?
YSI EXO3 Multiparameter Sonde EXO3 is a purpose-built sonde for monitoring major water quality parameters, including: pH, conductivity, temperature, turbidity and dissolved oxygen.
What is a sonde survey?
If you suspect a collapsed drain or a blockage, a sonde can work in partnership with a CCTV camera for a sonde drainage survey to assess exactly where the problem is located, what depth it’s at, the severity of the issue, and any potential obstacles to a resolution.
What is a sonde trace?
A sonde is a self-contained battery operated transmitter used for tracing the paths of pipes, ducts, sewers and drains and in the precise location of blockages or collapses.
What is sonde in well logging?
The elongate cylindrical tool assembly used in a borehole to acquire a well log. It contains various energy-input devices and/or response sensors. The sonde is lowered into the borehole by a multi-conductor cable, or wire line.
How many types of borehole do we have?
– There are in fact three major categories of well : dug wells, driven wells and drilled wells, commonly known as boreholes.
What is a sonde for water quality?
The EXO2 water quality sonde is a new YSI multi-parameter instrument that collects data with seven user-replaceable sensors, a central wiper to keep sensors clean of biofouling, and an integral pressure transducer for depth. YSI’s best-in-class EXO2s, is built for spaces and places that can’t accommodate the EXO2.
How does a sonde locator work?
Locating and tracing a sonde The sonde radiates a Peak field from the center of its axis with a ghost signal at each end of the Peak. Move the locator a little way behind and then in front of the axis of the sonde to detect the ghost signals. Finding the two ghost signals positively confirms the locate.
How do you trace a sonde?
To locate a sonde:
- Move the locator backwards and forwards and stop when the bar graph indicates a Peak.
- Rotate the locator as if the blade is a pivot.
- Move the locator from side to side until the bar graph indicates a Peak.
- Repeat 1, 2 and 3 with the antenna vertical and resting on or just above the ground.
Do 512 Hz Sondes work with Schonstedt devices?
512 Hz sondes and many other 512 Hz transmitted devices work with any Schonstedt pipe & cable locator model. Sondes benefit a variety of industry applications. In water & sewer, they can help pin-point blockages or pipeline defects when used with video inspection systems.
What is a 50 ft locator sonde spring coupling?
More power locates 50 ft. Locator Sonde Spring Coupling fits between the end of a Flexrod and the sonde to reduce the shock to the sonde when hitting the wall of a pipe or to ease the sonde around bends. The spring coupling has a M10 male thread and a M10 female thread.
What is an ozone sonde?
Sondes are small, self-contained radio transmitters, which create an electromagnetic field of their own. The KC96 ozone sonde type is a modified version of the KC79- and the earlier KC68-sonde, which was developed by Kobayashi and Toyama in 1966.
What is a sonde used for in construction?
You can trace a path and determine the depth of a non-metal pipe such as HDPE, PVC, transcite or clay tile. In cable applications they can be used to trace empty fiber-duct or adjacent conduit runs and stop at unmarked underground vaults or splice boxes. The depth accuracy of a sonde’s position can help reduce excavation costs and time.
