Inclisensor

04/09/2009 1:21 AM

Hi All!

Can you guide me about inclisensor?

I've viewed it in cloth dyeing machine. It is being used there for measurement of angular movement. It has been installed on an end of a shaft. This shaft rotates 0 ~ 120 degree.Sensor gives 4 ~ 20mA output when it rotates with shaft. This output signal is used to vary speed of motor through VFD and maintain required tension on cloth. I could not understand its working principle. I need some sensors as machine spares. but could not find any brand or details about this sensor.

"A tensiometer measures the force with which water is held in the soil by the soil par-

ticles. This force, referred to as soil suction, tension, or potential, indicates how tightly

the water is bound in the soil, and how much energy must be exerted by plant roots to

remove and use the water."

Are you sure tensiometer can be used here????

"Tensiometer" is the accepted name for a device that measures soil suction.

http://soil.scijournals.org/cgi/content/full/65/1/1

However, the term is also applied to instruments that measure other kinds of tension, and even tensile strength.

viz. An instrument for measuring tensile strength.

viz. An instrument used to measure the surface tension of a liquid.

It sounds like an encoder to me. Simply measures the speed of rotation and sends out a proportional signal. This is used then to make sure the motor is at the speed it's supposed to be. I would hazard a guess that you also have a load cell on one of the shafts to measure tension. The signal from this, along with the tension setpoint, is used to vary the motor speed to obtain the desired tension.

Thanks Mike!

Before viewing this sensor, I also assumed that this could be a rotary encoder but my assumption was wrong. This sensor is of rectangular shape and it has been coupled/installed on shaft end and it rotates along with shaft. There is no stationary part of sensor. In rotary encoder, body of encoder remains at standstill position and its shaft rotates with the moving object. and rotary encoder does not give and analog output, it gives pulses. So it cannot be a rotary encoder. I can provide you its model: IS420-60-1B, Brand: EMS USA, Output: 4 ~ 20mA, Marked on sensor: Inclisensor. Can you please find out and help me? I need this sensor urgently.

OK, now it makes sense. I think it is an inclinometer. Giving you an output proportional to the degree of inclination from some reference point. Have you looked for inclinometers?

O.K Thanks!

Now I've found many brands and I have now clear about its working principle.
