Digital Output Transmitters — HART, CAN Bus, SDI-12 & USB
The Series 400–900 digital line of pressure, level and temperature transmitters with HART, CANbus, SDI-12 and USB outputs.

GP:50's Series 400–900 digital line covers pressure, level and temperature transmitters with digital outputs, and these protocols can be added to most of its analog transducers. The Model 411/411XP adds HART to a 4–20 mA signal with CSA and FM approvals, and the Model 540 uses CANopen so several devices can share one bus.
The Model 611/612 connects directly by USB, with field configuration and GP:50's data logging software, for ranges from 0–1 psi to 0–100,000 psi. The Model 913 submersible level transmitter has an SDI-12 output for environmental data loggers and low power draw for remote wells.
