Wotian new product-PCM9880 wireless pressure transmitter

From: Issued date 2021.06.18 Back

product description:

The PCM9880 wireless pressure transmitter is a high-precision intelligent instrument powered by a lithium sub-battery and has wireless communication function. The main application field is for the field or the occasions where the supporting power supply environment is inconvenient, such as heating, water supply, oil, gas pipelines, etc Perform pressure monitoring on occasions, and send data such as equipment power, signal strength, pressure information of the pipe network, and alarm information to the monitoring center in real time through the wireless network. The monitoring center stores, analyzes, inquires, and processes alarm information to realize signal wireless Transmission and information interaction do not require on-site wiring, saving manpower and construction costs, and helping users realize timely and efficient supervision of the pipe network.
