PT802 LoRaWAN® wireless pressure transmitter is composed by two parts: pressure measuring part and transmitting part. Cable with connector connect two parts together.
The pressure measuring part is used to measure process pressure, and it measures field value and converts it to analog voltage signal and sends the signal to the transmitting part.
The transmitting part controls power supply for pressure measuring part. It switches on power supply for pressure measuring part at sample time interval and reads the analog voltage signal returned by pressure measuring part. The transmitting part reports the pressure value timely at timely report interval. When pressure passes beyond threshold or when there is a variation, the transmitting part will send alarm message to server.
Users can configure the device parameters with AT commands via on board TTY serial port, including network access parameters, time interval, alarm threshold value and etc.
PT802 is powered by internal battery ER34615.The battery is non rechargeable with 3.6V nominal voltage. The battery needs replacement when it runs out of power.
The device can offer 0~1…700bar measuring ranges, and all kinds of process connection ports.
