Inappropriate use may lead to danger!
2.Product overview
CYYZ61 series pressure transmitters adopt OEM pressure sensor with
stainless steel diaphragm as signal measuring element. After automatic
testing by computer, temperature compensation of zero point and sensitivity
in wide temperature range is carried out by laser resistance adjustment
technology. The amplification circuit is located in the stainless steel
case, which converts the sensor signal into standard output signal, giving
full play to the technical advantages of the sensor, so that the CYZ61
series pressure transmitter has excellent performance. It is easy to clean,
anti-interference, small temperature drift, high stability, and has high
measurement accuracy. It is an ideal pressure measuring instrument in
pharmaceutical, food and other industries.
3.Working principle
The pressure sensors diffuses a wheatstone electric bridge on
mono-crystalline silicon, and stressed by the measuring media (liquid or
gas)to cause change of the bridge wall resistance value(piezoresistive
effect). In result, a differential voltage signal will be generated, which
converts the signal corresponding to the range into standard analog
signal(as shown in Figure 3-1)or digital signal.

Communication example（reading a sensor signal):
The sensor communication device address of 0-1.6 MPa is set to 01, ie
[Address]=01 (Address range 01-254);
And, CRC0=84, CRC1=0a. Then send and return data should be as follows:
Send: 01 03 00 00 00 01 84 0A
Back: 01 03 02 02 AC B9 59
02AC is hexadecimal, converted to decimal 684;
Data output: 0-2000 corresponds to 0-1.6 MPa, so the current pressure is
P=1.6*684/2000=0.5472MPa
Calculation formula: (range upper limit - range lower limit) ÷ 2000 *
current data + range lower limit = current pressure value
Query example(read the current device address, only to be completed
independently by a single sensor)
Send:FF 03 00 0F 00 01 A1 D7
Back:FF 03 02 00 01 50 50
Then: the address of this device is 01 (hexadecimal)
Example of modification
For example, change 01 address to 09 address:
Send 01 06 00 0F 00 09 79 CF
Retun 01 06 00 0F 00 09 79 CF
Then the original address 01 is modified to 09 successfully, and the
modification of address can be done offline or online. It can work
directly without re-powering at completion.

10.5. 16CRC verify
The 16CRC verification is a standard error check method used by the
Modbus protocol. Generally, it has detailed descriptions and procedures,
which is not explained here.
10.4.Precautions for use
a）Single RS485 bus must adopt a “hand-to-hand” bus structure. Do
not use a star connection or a fork connection. The address code is set
from near to far, that is, the management computer is connected to the
No. 1 controller, No. 2 is connected to No. 1, No. 3 is connected to No.
2, and so on...
Warning!
b)The AC power supply and the case of the equipment must be grounded
properly and well. There are many places where there are triangular sockets
which in fact, have no grounding at all. Be alerted. When the grounded
properly, the equipment to release the energy by combining with the
lightning protection design when struck by the lightning surge and the
static electricity, to protect the RS485 bus equipment and related chips
from damage. Do not use the RS485 bus if there is no grounding or not
properly grounded, to avoid equipment burnout and casualties.
c)Wire must use multi-strand shielded twisted pair cable with diameter of
more than 0.3 mm2 (multiple strands are for spare). Use PVC pipe separately to
avoid lining with strong current to avoid interference from strong current.
d)485 (A) and 485 (B) must be twisted together, because 485
communication uses differential mode communication principle, and twisted
pair anti-interference performance is good. It is wrong not to use twisted
pairs, and other types of cables.
e)Connect the RS485 converter and the reference ground GND (power
supply negative) of all access controllers, and use the remaining one or all
of the multiple twisted pair cables for the series GND; if the reference
ground is not connected, it will also affect the communication time.
Nowhere, high frequency radiation, mainly from distributed capacitance and
inductance, produces a common mode effect.
f)The shield of the network communication line is grounded. It is
required for grounding, otherwise the potentially danger of the bus is
unknown.
g)If multiple machines or cables are too long for communication, add
120 ohm matching resistors between 485 (A) and 485 (B) at the head and end
of the 485 bus, to improve the communication performance quality. (Must be
pair twisted)
h) The transmission rate, number of load nodes and transmission
distance should be reasonably arranged, to achieve remote low-node for
low-speed, short distance multi-node for high-speed principle.
i)The data communication shall be verified to protect the transmission
accuracy. Generally, the Modbus-RTU is verified by the crc-16 verification
mode, and the error rate is less than 1/1billion.
j)If necessary, choose the company's isolated type model 485, the price
is generally higher.
