New low frequency seismic sensor has been introduced.

We just introduced our new seismic sensor. MTLF 1040 has the performance the you can see on the site.

Couple of points on the device. There was a problem with the PC board design and power consumption is about twice the advertised level. We are working on redesigning the board and hope to be fully compliant with our specs in the next three to four weeks.

We are setting up the production capabilities that will allow us to produce op to a hundred sensors a month in about three to four months. Then we will be able to drop the price to $585. Eventually we would like to drive it down more.

Very gad that we finally have a real product.

Rotational sensors for seismic sensing

I got several emails/call over the last month about creating something like a 6 DOF inertial unit for registering S and P waves during seismic sensing. People were interested in our angular Rate Sensors as components for such devices. as far as I understand the interest was to record rotational signals of about 10 ^( -8) radians / sec and greater. Bandwidth from a few HZ up to 100 HZ or more.
I am surprised by the fact that so many people are interested in this application simultaneously. People are talking about thousands of units.

I am getting inquiries regarding the MET 1050 sensors that we advertised will be released in October.

I believe we are still on schedule to have commercial samples by then. The updated specs for the samples as follows:

MET 1050

Parameter
Operating principle	MET transducer with feedback
Natural frequency fn	1 Hz
Tolerance	5 %
Maximum tilt angle for specified fn	Omnidirectional
Distortion with 0.7 in/s p.p. coil-to-case velocity	0.1%
Distortion measurement frequency	10 Hz
Sensitivity*	300 V/m/sec
Tolerance	5%
Spurious frequency	400 Hz
Equivalent input noise	10 nm/sec/√Hz at 10 Hz; 3 nm/sec above 50 Hz
Power supply voltage	12 V
Power supply current	7.5 mA
Temperature Range	"-55ºC to +85ºC
Input limits	10 cm/sec at 60 V/m/sec scale factor
Dynamic Range	126 dB @4 msec
Frequency dynamic response	"+-0.25dB**"
Linearity Error	<-+0.1% of full scale
Geophysical Standard THD	better than 0.1%
Size and weight	TBD

*-Could be adjusted in the range of 30-300 V/m/sec

We are considering narrowing the band to 1-300Hz for the samples since it is just simpler to do at the them and will save us some time.

One can certainly put together three of the samples and create a threeaxis assembly.

Please let me know if you what to be put on a waiting list for the samples. bindler@mettechnology.com.

questions on sensors.

In the next couple of days I will put some question that people ask about the sensors.

Inertial sensors.

hi, I am starting this blog to provide more convenient and up to date forum for exchanging information and answering questions related to our sensor technology. I am CEO of MET Tech that has developed a novel inertial sensing technology. Our products include linear and angular accelerometers, velocity meters, inclinometers, as well as gyroscopes. They are used in a broad range of industries such as oil and gas exploration, homeland security, aerospace and automotive industries and in numerous applications, including guidance, navigation, control, safety systems, and robotics. They operate in mobile devices (including cell phones), lap-top computers, gaming consoles and many other consumer goods.

Please visit our website at www.mettechnology.com for information on the company and its products.
