The EV-120 is a digital pressure indicator, designed for use in conjunction with a KELLER Series 30 transmitter. Together, these two instruments build a highly precise pressure measuring device. At startup, the EV-120 communicates with the Series 30 transmitter and displays the full-scale pressure range of the transmitter, then displays the current pressure value, updating twice per second.
No manual adjustments are required; the EV-120 automatically configures itself to any Series 30 transmitter. Because the pressure is communicated and read in digital format, there are no signal conversion errors.
