The coil resistance is ohms and has an undamped output voltage of The manufacture does not supply the resistance needed for a damping of. This price includes the three sensor elements, case, spikes and mounting hardware.
This item is not in-stock. There are two versions of the wire sensor. The other version is for our differential input Bit Digitizer board.
See photo above. Other lengths of wire are possible. Please contact us for a quotation. The wired version does not come waterproofed. The user will need to do this themselves using some sealant like RTV in both ends of the sensor. Sensor channel orientation and additional DB15 Pinout information can be found here. Here are some test measurements performed on one of the Longet LGT 4. Of note is the No Load Transducer Gain of the sensor.
The manufactures data sheet lists the output at 0. Geophones, with periods around 1 to 2 Hz, are short period devices designed to record local or large regional events. The higher frequency sensors 4. Geophones with periods around 4. Short period sensors will not record distant teleseismic events very well, if at all. Depending on your location they may pick up the P wave of large teleseismic events.
If you live in an area where you will only be recording teleseismic events you should not consider using a short period device. To record all of the different waves produced by a teleseismic event you will need a long period device like a LehmanShackleford-Gundersenor broadband sensor.

A geophone is a tiny sensor used to measure seismic activity by converting ground movement into voltage. Why do we need that?
Because the nature of the initial signal is analog which means that computers cannot read it. What geophone does is converts the data into the digital format which electronic machines can easily process. EGL Equipment Services Co, Ltd offers high-quality geophones for sale at competitive prices to clients from all over the globe. The device consists of a mass that hangs on a set of springs. The mass is surrounded by a magnet inserted into the Earth.
The ground movements at frequencies less than the resonance frequency cause the suspended mass to move too. The movement of the mass causes the magnetic field to produce the electrical voltage in the wire wrapped around the mass. The response of the magnet is proportional to the ground velocity.
