APTSS-21 wireless pressure transmitter is a high-precision, low-power wireless pressure detection instrument independently developed by our company. It consists of a pressure sensor, a signal processing circuit, a communication module and a power module. It is powered by a large-capacity high-energy lithium battery and transmits data via radio frequency. This instrument is easy to install and use. It does not require on-site wiring, which saves the trouble of wiring bridges for conventional instruments, saves manpower and construction costs, and is especially suitable for occasions where wiring is difficult and power cannot be supplied. It is an ideal upgrade product for traditional pressure transmitters.
