A water pressure transmitter is a device used to measure water pressure in a variety of applications. It is typically used to monitor fluctuations in the pressure of a water system, allowing for the early detection of system problems. The transmitter is composed of a pressure sensor connected to an electronics module. This module converts the pressure reading into an electrical signal that can be displayed or transmitted to a control system. A water pressure transmitter works by sensing the difference between atmospheric pressure and the pressure of the water or fluid in the system. The pressure difference is then converted into an electrical signal with a linearized output, which is then transmitted to the control system. This allows for constant monitoring of the system, giving users the ability to make necessary changes to keep the water pressure within desired levels. The use of water pressure transmitters allows for early detection of system problems, which in turn can prevent more costly and time-consuming repairs.
