Overview:

This series of sensor using a capacitive polymer humidity sensitive element, a temperature measurement element gap to material, and on the same chip, and implementation of 14 bit A/D converter and serial interface circuit of seamless connection, ensure the long-term stability of the product has high reliability and good will. The 32 bit microprocessor per second is the product of temperature and humidity on sampling for dozens of times, calculate the signal average value according to the filter time and sampling frequency, to ensure the effect of interference on transmitter minimum external, time average filtering is one second, the range and the filtering time through software stationary.

Special point

Fast linear response

485 signal output, communication protocol: MODBUS RTU

Temperature and humidity range programmable, wide measurement range, high accuracy

Signal filtering function, more stable and reliable performance, stronger anti-interference ability

Technical Specification:

Installation:

The wind tube type transmitter should be installed directly in the air, mounting location choice in temperature and humidity can be accurately detected region (from the fan coil pipe or 2-3 meters outside the location, can get good measurement effect).

1. In the air hole diameter is 13mm, with 3 self tapping screws flange is fixed on the air duct
2. Open the upper cover
3. According to the correct wiring connection signal cable
4. Insert the transmitter, which is fixed on the air duct
5. Install seal, tighten the screws

The contents of the agreement:

RS485 communication, we must first confirm the master-slave baud rate, baud rate is not the same will lead to communication failure. Baud rate setting: 9600bps, parity bit: No, data format: 32 bit floating point number, double word.
