The Pentair Point Four Systems TGP Transmitter is a stand-alone probe for the measurement of total dissolved gas pressure. It provides measurement for TGP (mmHg or % saturation), ΔP (TGP-BP), barometric pressure (BP) (mmHg) and temperature (ºC).
Two analog outputs are available from each TGP probe. They are available in 0-20 mA, 4-20 mA or 0-5VDC and can be configured to any of the five available measurement parameters. Measurements are also available via RS-485 and can be viewed on a PC with the optional software package. TGP probes are not loop-powered and can accept a 9-33VDC power supply. 115VAC to 12VDC power supply is optional.
