Textile product having an integrated sensor for measuring pressure and temperature
First Claim
1. A paper machine band comprising a textile product having at least one monofilament or profile element on which is arranged a layered sensor for measuring pressure and/or temperature, wherein the sensor is constituted from at least three layers arranged on the monofilament or profile element, the second layer having piezoelectric properties and the layers in contact against the second layer forming electrodes that are couplable or coupled to an analysis device.

Abstract
The invention concerns a textile product (6) for use in a paper machine, having a monofilament or a profiled structure as support element (1) on which is arranged a layered sensor for measuring pressure and/or temperature, and is characterized in that the sensor is constituted from at least three layers (2, 3, 4), the second layer (3) having piezoelectric properties and the layers (2, 4) in contact against the second layer (3) forming electrodes that are couplable or coupled to an analysis device.
The invention further concerns a method for producing such a textile product.

22. The method of monitoring a preselected parameter of a paper machine clothing operating in a paper-making machine, comprising the steps of:
-
a) providing a paper machine clothing having a piezoelectric sensor incorporated into the clothing, the sensor including a wireless transmitter; b) operating the clothing in a paper-making machine and thereby subjecting the clothing to a load acting upon the sensor; c) sensing with the sensor in response to the applied load the preselected parameter; d) transmitting with the transmitter a signal indicative of the preselected parameter; and e) analyzing the signal and thereby monitoring the preselected parameter.
