     Subject: Ultrasonic Sensors

Dear Sirs, 

Project No. 1:

We going to measure the height of a rising polyurethane foam in a narrow gap. Distance between sensor and bottom of gap: +/- 200 mm. Distance between sensor and cured foam: +/- 20 а 50 mm (setup can be slightly modified for the distances but the minimal range is +/-180 mm). Width of the gap is variable: 15 to 30 mm. Resolution for this measurement can be +/- a 1 mm. Output signal analog 0-10V or similar.

Matter rather urgent.

Qts. needed: +/- 50 pcs

Project No. 2:

We are looking for a low cost ultrasonic sensor for measuring the movement of a door frame while hitting/closing the door with different forces. The movement is rather small and ranges from 0,1 mm to max 10 mm. Do you have a possible solution ?

Qts. needed: +/- 8 pcs

From Charles Gilbert - 27.10.2005

     Subject: Electronic Design for Seismometers

I am presently doing consulting in low-noise electronic design for seismometers and scientific instruments. I have been thinking about the need for lower noise in commercially-available amplifiers. Low-noise op amps can achieve input noises on the order of about 1uV between DC and 10Hz. I believe it is possible for me to build a modular or hybrid op amp having an input noise ten times lower than this, on the order of 100nV rms between DC and 10Hz. 

I am curious to know if anyone thinks their might be a need for this kind of amplifier.

From Jeff Schulz - 11.08.2005

     Subject: Laser 2-Axis Displacement Measurements

We're looking for a 2-axis laser receiver that can handle up to three or four inches of movement in an outdoor setting. It is for monitoring vertical and horizontal movement in large civil structures as they are loaded.

Our hope is to implement it something like the following list, and we are somewhat flexible on most of these.

1) We would mount the receiver on the structure, anywhere from 20' to 80' away from the laser transmitter such as a standard handheld pointer.

2) This pointer would remain motionless as the structure moved. The receiver could possibly move left and right and also up and down, with a maximum of 4 inches in either direction.

3) Accuracy would need to be hopefully in the several-hundredths inch range.

4) We would like to read analog outputs from the receiver directly into our data acquisition system. Hopefully plus/minus 5VDC output for each direction, but other possibilities can be considered.

5) We're assuming that we need to read from the receiver end, but if there's a way to read this from the laser end, that would be fine as well.

Thanks !

I think that it can be any laser sensor. This sensor must be high temperature protected if we will install it inside of melting chamber.

I work for a company that produces ball and roller bearings. We are looking for a sensor that can detect a ball (metal or ceramic) through outer rings which have various wall thickness. The balls will be in motion riding in a track or "raceway". Our effective wall thickness ranges from approximately .050" to 1". Essentially we are looking for a sensor that acts like a proximity switch, however if needs to have the ability to see an object moving behind another object (without inducing any magnetism). This has not been an easy search thus far. If you can shed any light on this it would be greatly appreciated.

I am basically trying to build a gas detector which can identify at least 4 different gases using LEDS to identify them.

The output is an analogue voltage which is characteristic to the identified gas. The programmable logic device is going to be used to select the appropriate LED for the identified gas.

I do not want to use a microprocessor or any type of memory for the identification process mainly because the sensor is required to be hardware based.

I am looking into interfacing a gas senor with a programmble logic device. Could you be kind enough to email the circuit diagram ?

     Subject: Need contactless insitu pkg measurements: RH & T w RF communication?

Are there inexpensive small battery operated sensors that record and/or communicate the internal conditions of a package, without opening them? 

Some sensors would be in use for 12 mo. They would need to survive exposure to a acidic organic solid at ambient temperature. Data collected: relative humidity and temperature. One device preferred.

Individual poling by ID would be nice but is not necessary if the transmission range is short.

Sensors would be placed in the middle of a 30 gallon fibre drum filled with the solids.
