Range Expand: The 4-20 mA analog output can be made to represent any segment of the measuring scale. The isolated output is isolated from the input, ground line power and all other outputs Non-isolated 0-1 mA, 100 ohms maximum load Non-isolated 0-5 Vdc, 1000 ohms minimum load Isolated 4-20 mA, 800 ohms maximum load Both panel and pipe mount kits can be ordered separately.ĭ.O.: 0-20.00 ppm and 0-100% saturation, switch selectableĩ8-132 Vac, 50/60 Hz (less than 10 VA) Optional: 196-264 Vac, 50/60 Hz The standard unit is provided with mounting hardware for surface mount applications. The instrument is housed in a NEMA 4X enclosure. A password feature protects the stored values. The integrity of the system is ensured with a watch-dog timer and system alarm. The instrument can also be used to take a temperature reading and one of the non-isolated analog outputs can be used to give a continuous temperature signal. The analog outputs may be programmed to represent any segment of the measuring scale.Ī membrane perforation alarm is provided which gives early warning of a membrane failure. The instrument provides non-isolated 0-5 Vdc, 0-1 mA and isolated 4-20 mA analog outputs. The instrument must be used in conjunction with the AquaMetrix Model P91 dissolved oxygen sensor. Calibration is also accomplished through the front panel menu. Outputs are programmed through the menu with push buttons on the face of the instrument. The AquaMetrix Model 2200D Dissolved oxygen analyzer is a versatile industrial microprocessor based instrument.
