A simple pressure measurement system can be configured from a Keller pressure transmitter and one of our digital pressure indicator/power supplies. Our digital indicators are available for operation from DC or AC supply, provide a DC supply to the pressure transmitter and display the transmitter output. The display units can be chosen and scaled according to the specific transmitter in use. Certain models repeat the analog transmitter output and other models accept an RS485 digital output from transmitters so equipped. Also available are models with output relays and high-low alarm capability.
