The ACD-102 pressure transmitter (backup battery) is a combination of our company's digital pressure transmitter technology features, with an added built-in battery, allowing the transmitter to perform pressure detection even without external power. The transmitter not only has the (4-20) mA analog signal output function of the transmitter, but also optional RS485 digital communication function and (5-30) Hz function; It has a rare five digit LCD backlight display for pressure transmitters.
