KS-SHT temperature and humidity transmitter user manual
Product introduction) KS-SHT series temperature and humidity transmitter is used to collect the temperature and humidity in the air, and the output can be 0-5V, 0-1V, 4-
20mA, 0-10V, RS485 and other signal output methods, can be connected to paperless recorder, intelligent display instrument, PLC, computer, human interface and other display devices, used for high-precision temperature and humidity collection, the sensor uses intelligent The computer has its own calibration technology. The sensor has been calibrated before leaving the factory for the user to use directly without correction.

At present, most computers have no serial port, so USB conversion cable is used. Multiple devices can be connected to the computer through a converter. A computer can be connected to more than 100 devices. The computer distinguishes different meters through the meter address. After connecting the device to the computer, please set the communication address in the device system parameters. It is consistent with the communication address on the software. If there is only one device, use the default address of our software.

The transmission range temperature of all sensors is -45-125 degrees (customizable range). Take the 4-20mA output signal as an example. The external paperless recorder of our factory sets the instrument input signal type to 13 to indicate 4-20mA input for temperature. Signal, the upper limit of the range is set to 125.0 in the input setting. For the temperature signal, the lower limit of the range is set to -45.0 in the input setting. For the temperature signal, the upper limit of the range is set to 100.0 in the input setting. The lower limit of the range is set to 0.0

Important note The color of the sensor pin depends on the color of the terminal. This figure is a wiring diagram of the temperature and humidity sensor output of 4-20mA. The sensor output temperature range is -40-125°C, set the upper limit of the instrument range 125°C, and the lower limit of the range -40°C
If the output humidity range of the sensor is 0-100%, set the upper limit of the instrument range to 100% and the lower limit to 0%
The input type is 13 when the paperless recorder corresponds to 4-20mA, then set the input type to 13
O① Connect the 24V positive output of the meter to the red line of the temperature and humidity sensor (24V positive) 2② Connect the 24V negative output of the meter to the black line of the temperature and humidity sensor (24V negative)
3③ The signal ground wire is shared with the negative terminal of the power supply. Pull the black wire of the sensor to the G terminal of the recorder
④When the sensor output is 0-1V or 0-5V, connect the yellow wire of the temperature signal to the B terminal;
(⑤ When the sensor output is 4-20mA, connect the yellow wire of the temperature signal to the C terminal;
(6⑥ When the sensor output is 0-1V or 0-5V, connect the humidity signal green wire to the B terminal;
⑦When the sensor output is current 4-20mA, connect the green wire of humidity signal to terminal C;
