3. The basic principle of torque measurement
Torque measurement: The strain gauge electrical measurement technology is used to form a strain bridge on the elastic shaft. The electrical signal of the elastic shaft torsion can be measured by supplying power to the strain bridge. After the strain signal is amplified, it is subjected to pressure / frequency conversion. Becomes a frequency signal proportional to the torsion. as the picture shows:

Fourth, the basic principle of speed measurement

Rotational speed measurement: The magnetoelectric code disk is used for measurement. Each magnetoelectric code disk has 60-180 (optional) teeth. The shaft drives the magnetoelectric code disk to produce 60-180 (optional) pulses per revolution, high speed Or in the medium speed sampling, the frequency measurement method can be used, and in the low speed sampling, the accurate rotation speed can be measured by the period measurement method. Speed ​​measurement can be up to 15000rpm. The accuracy of this sensor can reach ± ​​0.1% ～ ± 0.5% (F · S). Because the sensor output is a frequency signal, it can be sent directly to a computer for data processing without AD conversion.

The speed measurement method of this sensor adopts built-in speed measurement, the user needs to indicate whether to monitor the speed signal when ordering.

5. Product features:

1. The square wave amplitude of the signal output waveform can be selected from 5V / 12V / 15V / 24V.

2. You can enter the working state within 5 minutes of starting up without preheating process.

3. High detection accuracy, good stability and strong anti-interference.

4. The forward and reverse torque can be measured continuously without repeated zero adjustment.

5. Small size, light weight, easy to install.

6. The sensor can be used independently from the secondary instrument. As long as the power supply of ± 15V (200mA) is provided according to the pin number of the socket, the frequency signal of equal square wave or pulse wave with impedance proportional to torque can be output.

18. Communication function

1. Data format: The data format is 10 bits: 1 start bit, 8 data bits, no parity bit, 1 stop bit.

2. Baud rate: fixed at 9600bps.

3. The communication address of the instrument: fixed to 01, (if there are special requirements, please indicate when ordering).

● All commands sent and received by the instrument are ASCII codes. For the ASCII codes of common symbols, see the appendix ASCII table.

● The meter automatically recognizes whether the command has a check core. If the command sent by the host is with a check core, the meter will also reply with a check core. It is recommended that all data transmitted should have a check core, which can prevent errors The data is received, improving the overall stability of the system.

● About the verification core:

Features:

The check core helps to detect command errors from the computer to the meter and to detect wrong answers from the meter to the computer. The check core function adds 2 characters to the command and answer strings without affecting the transmission rate.

Set up:

Whether to use the verification core does not need to be set for the instrument, the instrument automatically determines whether the command issued by the computer contains the verification core. If the command contains a check core, the instrument automatically adds a 2 character check core when answering. This means that the computer can use a check core for certain instruments or certain commands in the network in a targeted manner.

format:

The verification core ranges from 00 to FFH, which is represented by 2 digits of 40H to 4FH ASCII code, and is sent before the end character of command or answer \"¿\" (0D). If the verification core in the command issued by the computer is incorrect, the meter will not answer.

Calculation:

1. The check core of the command is equal to the sum of all command ASC II code values. The remainder is retained when it exceeds the range.

2. The verification core of the answer is equal to the sum of the ASC II code values ​​of all the answers plus the ASC II code value of the address of this instrument. The remainder is retained when it exceeds the range. Example description: sending and receiving format and calculation method of check core.
Example: This command: # 0102NF¿

(Ie send hexadecimal to the meter: 23 30 31 30 32 4E 46 0D)
Answer: = ＋ 123.5LB¿

(That is, the instrument sends out hexadecimal: 3D 2B 31 32 33 2E 35 4C 42 0D)

The verification core of the sent command string is calculated as follows:

Verification core = 23H + 30H + 31H + 30H + 32H = E6H
#, 0, 1, 0, 2 ASC Ⅱ codes are 23H, 30H, 31H, 30H, 32H The sum of these ASC Ⅱ codes is E6H, using two 40 ~ 4FH ASC Ⅱ codes as 4EH, 46H, namely N, F .
The verification core of the answer string is calculated as follows (the two ASCII codes after sending the delimiter are the address of the instrument):

Verification core = 3DH + 2BH + 31H + 32H + 33H + 2EH + 35H + 41H + 30H + 31H
= 1C2H

=, +, 1, 2, 3, ·, 5 ASCII codes are 3DH, 2BH, 31H, 32H, 33H, 2EH, 35H and the sum of these ASCII codes plus the ASCII code 30H of the instrument address, 31H is 1C2H, The remainder is C2H, which is expressed as 4CH, 42H, that is, L and B, using the two-digit ASCII code of 40 ~ 4FH.

Command 1: # 0100↙

Command for reading torque value. (Answers start with \"= \" and end with carriage return)

Command 2: # 0101↙

It is a command to read the speed value. (Answers start with \"= \" and end with carriage return)

Command 3: # 0102↙
