The device works as follows.

0 way.

 When a rolled product appears in the measurement zone, a signal appears at the output of the sensor 15 for the presence of metal, which is supplied to the first input of the key .18 and the input of the time sensor 16, the output

which is connected to the control inputs of the keys 19-21 and to the input of the reset control unit 22. The time sensor 16 detects the cycle i of the device operation time, which consists of t (- measurement time, t2 - rewriting time and device resetting. At the measurement time i, the keys 19 21 are opened. From the technological parameter sensor 1, information about the value of It is fed to the first input of block 4 of the current values of the process parameter, to the first input of block 17 of the previous measurement memory and to the first input of block 23 of the rewrite control.

The previous measurement memory unit 17 has one input counter and two auxiliary ones. The input value of the input parameter receives the current value of the parameter, and information about the previous measurement is stored in the auxiliary meters. Auxiliary counters of the previous measurement memory block 17 are connected via comparison circuits 26 and 27 with block 4 of the current parameter values. On the scheme

26 comparison from the previous measurement memory block 17 displays the maximum allowable value of the current value of the parameter, and comparison circuit 27 displays the minimum possible value of the parameter. In case of equality of the number codes in the current measurement block 4 and the auxiliary counters of the memory block 17 of the previous measurement, the comparison circuits 26 and 27 generate signals, through the keys 20 and 21 arrive at the fourth and fifth

the inputs of the control unit 23 restart

pysyu.

At the end of the time, 1 t is measured, the keys 19-21 are closed, and the status of the outputs of the keys 20 and 21 is stored in the rewriting control block 23. At the time i of rewriting and resetting the device to the initial state, the signal from the output of time sensor 16 is fed to the input of the reset control unit 22. At the first input of the reset control unit 22, the overwrite permission signal is set, which is fed to the second input of the overwrite control unit 23, and if the fourth input of the overwrite control unit 23 receives a signal from the circuit

27, but the signal from the comparison circuit 26 did not arrive at the fifth input of the rewrite control unit 23, the rewrite control unit 23 generates information signals of the current measurement to the inputs 6-8. Keys 6 - 8 are switched by switchboard 5 zones of length, which operates according to p program,

counter 3 lengths, connected with sensor 2 pulses of length. When a signal appears at the second output of the reset control unit 22, the signal at the first output of the same block disappears, and the signal from the second output goes to the third input of the rewrite control block 23 and sets it to its initial state. If codes 00 and 11, respectively, are fed to the fourth and fifth inputs of the rewrite control unit 23, the rewrite control box 23 is reset.

When a signal appears at the third output of the reset control unit 22, the signal at the second output of the same block disappears, and the signal from the third output goes to the third input of the previous measurement memory block 17 and to the second input of the 4 block of the current process variable value. This signal resets to O the auxiliary counters of the memory unit 17 of the previous measurement and the block 4 of the current value of the process parameter. When a signal appears at the fourth output of control unit 22, the signal at the third output of the same block disappears, and the signal from the fourth output goes to the fifth input of memory block 17 of the previous measurement. By the same signal, the contents of the input counter of the block 17 of the memory of the previous measurement is rewritten into auxiliary counters of this block. When a signal appears at the fifth output of control reset unit 22, the signal at the fourth output of the same block disappears. The signal from the fifth output goes to the sixth input of memory block 17 of the previous measurement and to the second input of key 18, the output of which is connected to control key entry 25. When a signal appears at the sixth input of memory block 17 of the previous measurement | the travel counter of this block is reset to O. The key 25 is opened, and the number of pulses specified by setpoint 24 is added to the first auxiliary counter of memory block 17 of the previous value, and the set value of setpoint 24 is subtracted from the number of pulses recorded in the second auxiliary counter. The number given by setpoint 24 determines the maximum possible parameter changes in the time between two measurements, for example, the maximum possible temperature values 1 to 1 between two points on the strip. At the end of the time t for overwriting and installing the device and the initial state, the device is ready for the next measurement. Further, the operation of the device is similar. When the car leaves the measurement zone, the signal at the output of the metal sensor 15, and therefore at the time sensor 16 output, disappears. In this case, if the signals at the fourth and fifth inputs of the rewriting circuit 23 had the code 01, then the information inputs of the keys B - 8 signals of the current value of the parameter are received, if the signals at the fourth and fifth inputs, respectively, had codes 00 and ii, then the rewriting control block 23 was reset to its original state. The value of the maximum possible parameter is displayed on the comparison circuit 26, and the minimum acceptable value is displayed on the comparison circuit 27. The operation of the control unit 22 when the metal disappears from the measurement zone is similar to that described, however, the absence of a signal from the sensor 15 presence of metal at the second input of the key 18 and at the fourth input of the memory block 17 of the previous measurement does not allow to overwrite the previous measurement into the auxiliary counters the contents of the input counter of the same block and the number given by the set; com 24. The circuit is reset. ANNUAL economic a G4 18Gr; d -
