wireless pressure Transmitter
1. Summary
The wireless pressure measuring system is mainly used in the occasion where the power supply is not convenient or in the outdoor, such as the energy delivery pipe. It can realize the wireless transmission of the signal. With the wireless communication module, the system can monitor the aquired data by the PC.
The wireless pressure measuring system consists of terminal, router and net coordinator.
The CSS-T12 wireless pressure transmitter is the terminal of the measuring system. With battery supply, wireless communication function and LCD display, the CSS-T12 is a high precision smart pressure measuring instrument. the CSS-T12, using international advanced sensor, integrated circuit (IC) and accessories, is a high-precision, high quality, small volume, easy installation, use simple, cost-effective pressure transmitter. The CSS-T12 also can effectively prevent block of the signal channel and data losing. using the embeded Zigbee wireless communication module, the 2.4GHz radio frequency R-T device which is compliant with Zigbee protocol standard and the CSSMA/CA mechanism for conflict prevention.
2. Features of the wireless communication
Intermission working type, receiving current <55mA, emission current≤70mA, intermission current<3030µA.
The R-T time can be reset for reducing the power dissipation.
Wireless communication module, using the single chip micro-controller and RF IC, has a high reliability.
System bandwidth is 2.4GHz-2.4835GHz. there are 16 signal channels. The alternation of the signal channel is 5MHz
The system typical transmission rate is 9600bps, and the max transmission rate can reach 125kbps
high anti-interference ability, low BER, and the efficient forward error correction channel coding technology which improves the data anti-interference ability.
use the CSSMA/CA mechanism for conflict prevention, which prevents block of the signal channel and data losing.

Battery switch
The Battery switch is at the back side of the battery clip. Turn on the switch, the transmitter start working. Turn off the switch, the transmitter stop working.
7. Maintenance
When the reciever does not communcate with the pressure transmitter:
Check the distance between the reciever and the pressure transmitter. Is the distance far? Or is there a barrier?
Check the volume of the battery. If the volume of the battery is lower, please change the battery.
Check the antenna.
Please contact the supplier, if you have any troubles.
