I have two applications
for use in industrial research.
First I would
like to map the pressure distribution on impeller blade in a
stir tank. I would like to mouth the sensors on the blades then
coat it in polyurethane. Additionally I would like to measure
the vibrations along the shaft connected to the impeller.
Second I would
I like to map the pressure distribution inside of a ball mill.
I was think of
using tactile sensors for the pressure mapping. If your could
help me with choosing the required sensors and a quote for these
applications I would be very thankful.

I am a development engineer for Whirlpool Appliances and I have
a situation I need to address involving some small electric motors.
I need to be able to measure the gap between the rotor and the
stator of the motor while it is going down the assembly line
to final test. If the gap is to small, less than 0.005, I need
the motor pulled off the line.
Are you aware of any technology or supplier that can help supply
this type of measurement?

We start a first
automatisation of our process and we require partners for long
terms to buy our sensor and equipments.
PLEASE : If you
dont sell this sensors but an other type ==> send your catalogue
of sensors and others equipements for our futures projects
This first project
is named : GLS (grain levels sensors )
is to see on a screen the level of grain in 5 tanks of grain.
sensor transmit to plc, plc to screen the level of grain. Localisation
of each components aerien map :
5 sensors, working 4-20mA although the software for sensors with
RS485 will be fasted wire to connect all adaptors to connect
a good price and very good quality.
Sensors infos :
yes, the most important is to do according environnement of sensor.
- in tank of grains of 50 tons
- in temperature from -10 °c to 40° c,
- resistant of strong humidity ( rain , water condensation )
- very strong dust environment
- level of beans in tank is not flat but pyramidal to the top
( when we fill the tank) to the bottom when we are emptying the
- density of grains is 0,70 %
-humidity of grains is 12%
- a good mix between good price and good quality would be perfect
- a technology that your team know correctly would be the best,
to make sure of any surprise.
- long distance to cover between sensors and plc + 200 meters
( counting the cable detours, not in a straight line)
PLEASE : send
price offer for requirements (including price until france TOULOUSE)+
time to get it after order + if in stock + sheet specifications
of each products . Also please send your catalogue of sensors
and others equipments for our futures projects.
PS : if you have
sensor 4-20mA & RS485 please send 2 differents price

From: Carrick Hill
trying to find a sensor to pick up the presence of a metallic
(stainless steel) slug that is a link on a travelling axis (chain)
that is primarily made from PE based fiber rope always under
tension. The rope is normally dry but sometimes wet during sailing
at sea. The rope travels on a constant axis location and orientation
between points but the no symmetric slug can rotate on its own
axis preventing a constant sensing distance.
with am inductance sensor type solution is that the slug is not
symmetric about its axis (and cant made so for structural reasons)
so the sensing distance can vary anywhere from 3mm to 30mm depending
on its rotation and travelled position (that is not controllable
and so random). ie if constant (from symmetry) the sensing distance
could be tuned and more reliable sensing.
The system is
housed in a tight fitting alloy box with plenty of locations/space
for ideally mounting on CL
Hope that makes

I am a junior
high science/health teacher passionate about developing the next
generation of critical thinkers, innovators, and problem solvers.
We are working on a sensor project where the students would like
to design, measure/test and optimize ( a sensor that fits into
a metal pipe or attached ) the velocity of impact on a pipe and
see the results/rate of collision in real time, possible Tri-axial
data points and in kilometer per/hour, then collecting all data
on the effects of high-speed collisions and transmit wirelessly.
This dynamic behavior of the (ball or ?) hitting/bouncing off
a stationary pipe (or other metal surface).
I was wondering which effective tools existed to conduct fundamental
force measurements of extreme (collision) events in targeted
energy transfer in mechanical systems such as (impacts and responses).
sure what are the best (methods) force sensor, accelerometers/sensors
to measure and the best way to simulate this project with a wireless
component feature. Also, could this be compared to crash testing
a vehicle. These are the items/subject matter the class is researching
on the computer for help with this project. We sincerely appreciate
any/all technical assistance (through email communication).
placing/installing accelerometers or ?? in pipe

I have instaled a PT100 sensor (3 wire type) in a water pump
tank and it is connected to its relay. It should have 100 ohm
resistace brtween one wire and the other wires and the other
2 wires shoukd be short circuit.
But all the three wires are short circuit .
Can you explain me the problem and solution way?
Thank you so much

I am looking for a hardware interface/adapter to convert the
signal of a PT100 probe to a K-Type equivalent. The reason being
the data logger in use only reads K-Type thermocouple.
if you could recommend a solution.
