You can get one the size of a surface mount resister if you can use a -50 to 500 deg. C range. In order to get down to the -190 deg C, you need a coil style...
Hi group, I am interested in interfacing wheatstone bridge type pressure sensors, specifically : 1. SmartTec SPD015G 2. SX01DD4 Both are wheatstone bridge type...
Hi group, I would also like to build a ranging deivce based on the 40Khz peizo electric transducers. I had a look at EPE mag's/ John Becker's designs and they...
When I did something similar for college 20 something years ago I found I had to Transmit, Quench, then Receive. For several cycles I quenched the ducer with...
Hi again, Sorry for late reply, i have my final exams, and they are finished, but project not :S About errors, as you said Nick, its not easy to keep them in...

Hi, We sell a flexion sensor that may be of use to you. It's the BendShort sensor, see http://icubex.com/catalog/product_info.php/cPath/24/products_id/54...
Does anyone know how to measure the capacitance between a probe and a piece of metal that is not connected to the measuring circuit? The probe has an area of...

As the subject states, are there any huge significances in using an amplified vs an unamplified product? In my case, I am trying to measure the air pressure...
Ok, this is another answer a question with a question idea. First, is your present set-up (pressure transducer, labview, dac board) providing you with the...
I would add that electromagnetic interference (EMI) environment can also influence the choice between amplified and non-amplified sensor. If EMI is high, the...
Hi all I am designing a robot to detect certain shapes on a floor using IR emitters/detectors.I was wondering if you could help me with these questions: ...
I want to use ultrasonic sensors for obstacle detection for my system. I m designig system which can help blind people to move around. I have downloaded one...
... You need to the modulation and demodulation, when you have to reject the ambient IR (e.g. from the sun). If you need to sense reflected IR from your IR...
Dileep, C2 and C7 are decoupling capacitors for ICs. Each should be connected to Vcc pins of the ICs with a short trace on one end and to the ground on the...

Hi I'm kind'a new to this stuff. but wouldn't you want to mount heat sensors in multiple places over several flights to develop a crude map as to where to...
How about using temperature indicating crayons (like www.McMaster.com #3224K24) to tell you exactly what areas are getting how hot? You can easily check a...
I just had to comment, and give kudos to Sherpa---this is an excellant example of lateral thinking, and applying the best technology for the task at...
Hi everyone, I am doing a project on an automated irrigation system and ill need soil moisture sensors. I have been thinking to use gypsum blocks but it would...
Kurt I think, you don't need 2 sensors both behind and in front of the engine cooler. One (1) sensor in either place would give you almost as much information...
